Different types of material handling solutions, equipment, and machinery are used within supply chains to move, store, protect, control, and handle materials. The goal is to ensure that materials are readily available and that parts and finished goods are properly protected during transit to and from warehouses. Material handling is a critical component for manufacturers, warehousing, wholesalers/distributors, resellers, and retailers.

 
What is a Material Handling System?
A material handling system includes any equipment, vehicle, standing structure, storage unit, rack, or trolley involved in storing, transporting, and protecting materials, consumables, and finished goods. For manufacturers, a material handling system should be designed with short-range movements in mind. This means that production employees should be able to easily access and move raw materials, consumables, and work-in-process parts.
Why Is Material Handling Important?
Material handling is a critical component of protecting against damage to parts, raw materials, and consumables. This not only saves companies money but also improves final product quality by reducing defects. Material handling solutions should be part of a larger company-wide program to improve a company’s storage and handling practices. Only a proactive storage and handling process can protect against unforeseen and costly part damage.
Material Handling Systems Across a Supply Chain
Material handling solutions should simplify employee access to materials and parts so that the speed of work increases. Ideally, these systems should also be easy to modify and scalable to keep up with changing requirements. Across a given supply chain, material handling solutions are heavily relied upon as a means of meeting delivery requirements with minimal product defects.

1 . Production and Manufacturing
Material handling systems found in manufacturing include carts, flow racks, racks, tuggers, shelving, workbenches, workstations, boards, and other storage solutions. Each of these systems plays a critical role in supporting production employees by supplying them with the necessary tools, instruments, parts, instructions, and consumables to complete work orders.
2. Packaging and Transportation

Manufacturers typically ship their industrial finished goods on strapped pallets of corrugated cardboard containers. Corrugated containers and customized packaging are often used as a means of protecting materials from damage during transportation. They are also the most cost-effective way of transporting industrial finished goods. Strapped corrugated pallets help keep raw materials, consumables, and parts safe during transit.
3. Storage and Warehousing
The most common types of warehouse material handling systems include forklifts, lift trucks, hoisting equipment, shelving, pallets, pallet jacks, automated guided vehicles (AVG), and even robotic handling systems. Forklifts are the all-important vehicle in warehouse management. These are heavily relied upon to move corrugated and strapped pallets, while lift trucks can position pallets on high vertical shelves.
4. Wholesalers and Distributors
Wholesalers, distributors, and bulk resellers rely upon a combination of material handling solutions. Distributors typically use forklifts, lift trucks, and hoisting equipment to handle and store shipments. These are then broken down into smaller shipments which are then sent out to retailers. The focus is to minimize costs so incoming bulk shipments are often used as a means of lowering per-unit freight costs.
5. Retailers
Large retailers with large warehouses typically rely upon forklifts and lift trucks in addition to large shelving and storage units as a means of controlling finished goods. Smaller retailers may simply require pallet jacks, commercial hand trucks, warehouse stock carts, or small utility carts.
Problems with a Fixed Structure Material Handling System
Most portions of the supply chain don’t necessarily require customized modular material handling systems. There are instances where wholesalers, distributors, and large retail chains benefit from modular shelving and storage systems. However, manufacturers and fabricators are more heavily reliant on modular material handling systems if they want to adopt lean manufacturing, improve efficiencies, and control costs.

Unfortunately, for manufacturers, there are several inherent problems associated with a fixed material handling system like utility carts, trolleys, stock carts, or fixed shelving structures. The first issue relates to how several of these material handling solutions have welded joints or are designed and pre-manufactured to specific dimensions.

[caption id="attachment_36625" align="alignnone" width="1080"] This too heavy cart with inadequate wheels was a real source of problem for the team in addition to being a danger to their safety.[/caption]

Making any kind of adjustment to their dimensions or structure is both labor-intensive and time-consuming. This means spending a considerable amount of time having maintenance make changes. These changes often involve cutting, machining, and welding. For companies without these in-house capabilities, it means sending these structures out to third-party subcontractors.

Not only are third-party subcontractors expensive, but they can have drastic consequences on a company’s production throughput. It’s not uncommon for subcontracting to add weeks or even months for modifications to fixed structure material handling systems.

Second, as part of any continuous improvement plan, it’s common for companies to change their warehouse or shop floor layout. They may do this to reduce transit times between workstations and work cells, maximize available space, make room for a new piece of machinery or equipment, or increase their warehouse and production space to keep up with rising demand.

Once these changes are made, fixed structure systems that were pre-manufactured to specific dimensions quickly become obsolete. Companies must either cover the high costs of repair and refurbishment or purchase an entirely new material handling system.

Third, fixed structure material handling systems are by their very nature and design incapable of being flexible. They can’t be adjusted without a costly overhaul, repair, and refurbishment. This makes fixed structure material handling systems extremely problematic for manufacturers, especially ones adopting a continuous improvement mindset.
What do Manufacturers Need?
Manufacturers who adopt lean manufacturing principles need to reduce manufacturing cycle times and reduce transit times to increase production throughput. Sometimes that requires the willingness and ability to customize material handling systems for new product lines or new projects. Unfortunately, that’s not possible with fixed structure material handling.

Manufacturers must optimize their material handling systems throughout the entire production process. This means properly handing and storing incoming raw materials, while also improving the accessibility of those materials and consumables in lean work cells. Next, they need to reduce the transit times for semi-finished parts to adjacent work cells. When the entire material handling process is optimized, the company reduces waste, lowers manufacturing cycle times, and encounters fewer production delays.
The Benefit of a Modular Material Handling System
A modular material handling system is one where employees can make immediate changes to the structure’s layout without encountering extensive delays. These solutions typically include modular piping and tube and joint systems that can quickly be cut, extended, and joined in a fraction of the time compared to a fixed/welded material handling structure. Sometimes these changes can take no more than a couple of minutes.

Unfortunately, adjusting fixed material handling systems typically involves a substantial amount of industrial cutting, machining, and welding which can take days and weeks to complete. Modular systems are cost-effective solutions that are easy to assemble and disassemble without having to worry about extended lost time.
Improving Material Handling for Manufacturers

There are two essential criteria for optimizing material handling across the entire shop floor. First, a material handling structure inside lean work cells should be designed for minimal worker movement. This means parts, tools, materials, consumables, and semi-finished parts are easily accessible to production employees from within their work cells.

Second, the material handling equipment outside the work cell should be just as functional and easy to use as those inside the work cell. This ensures that transit times to move work-in-process parts to the next lean work cell in the production process are minimized.

When both the inside and outside of all lean work cells have optimized material handling structures and material handling equipment, it has the cascading effect of lowering production cycle times across the entire shop floor. After all, a single delay from a production work cell causes the next cell in the chain to experience delays until eventually, every chain in the process is behind schedule.
What can we build with a Modular Material Handling System?
There is simply no shortage of modular material handling systems that companies can make on their own using pipe and tubing systems. These products are perfect complements to a company’s constantly changing manufacturing environment. Without these modular piping solutions, companies would be faced with the high costs and delays of fixing, repairing, refurbishing, and re-welding older material handling equipment, or worse, having to purchase new ones.
Modular and Scalable Flow Racks
Most often associated with inventory and warehousing, material handling flow racks can also be placed in, or immediately outside of, lean manufacturing work cells. Having materials, parts, and consumables stationed in flow racks adjacent to work cells eliminates wasted transit times for employees from the work cell to the warehouse and back again. In essence, these material handling flow racks can sometimes act as small inventory retainers so that employees don’t waste time walking long distances for the materials they need to finish a work order.

Flow racks have an inclined design which makes it easy for employees to access the materials and parts inside production bins. Modular material handling flow racks empowers manufacturers to make relatively quick adjustments to the flow rack to account for a larger bill of materials. This could involve disassembling a portion of the flow rack to add more levels to handle more bins, or widening the length of each rack.
Modular and Scalable Carts

Carts have a multi-purpose function as material handling equipment. First, they help warehouse employees manage, move and store incoming shipments while also helping to prepare outgoing shipments.

Second, they are often essential for moving semi-finished parts and assemblies to and from separate work cells on the shop floor. Sometimes those semi-finished parts can be quite large, wide, or long. Third, they are ideal solutions for moving multiple production bins, parts, and materials for different work orders to different shop floor locations.

While carts have multiple uses, a modular and scalable cart built with tube and joint systems expands those uses and benefits ten-fold. Manufacturers know that nothing is static or stationary on the shop floor for long. Being able to adjust a cart’s size, height and width isn’t a luxury – it’s a necessity. Modular piping solutions empower manufacturers to adjust to any change in requirement.
Modular and Scalable WorkStations

Workstations are the all-important building block of any lean manufacturing work cell. A poorly-made or badly-designed workstation leads to endless wasted time as employees search in vain for poorly-placed parts, tools, instructions, bins, materials, or work orders. All this wasted time reduces operational efficiency.

If the workstation isn’t designed or structured around 5S principles (Sort, Set in Order, Shine, Standardize, Sustain) or worse, is not movement-friendly, then it’s no longer a lean workstation.

As important as a clean workstation is, it’s nowhere near as important as being able to adjust the workstation with modular piping solutions. Invariably, the workstation’s design will need to be changed, or modified at some point, and a fixed structure workstation is extremely difficult to adjust without encountering wasted time and high costs.
Modular and Scalable Racks

Racks are critical for holding inventory within warehouses. Not only do racks help to protect inventory, but their loading capacity means they can hold inventory for long periods. A higher loading capacity means each level protects the inventory on that level and each subsequent level beneath it.

It would be great if you only needed one type of rack with perfectly spaced levels that never need to change, but that is rarely the case. This is why a modular and scalable rack is so important.

Tube and joint systems allow you to create a tailor-made rack with individual levels you can adjust. Since inventory costs are typically based on warehouse square footage, a modular rack system allows you to free up valuable warehouse space, thereby reducing warehousing and inventory costs.

There is nothing more costly or time-consuming than having to change a fixed warehouse racking system. Modular racking can be made to fit the exact size and space you need to store materials, parts, and finished goods and are scalable and adaptable to support any change.
Types of Materials used to build a handling system
There are material handling systems that are pre-manufactured to specific dimensions and made with different types of materials. Ultimately, understanding the pros and cons of these materials is needed to better understand if they are viable solutions for your handling needs.

Aluminum Extrusions:

Aluminum is a lightweight, high-strength, and durable material that often has strong corrosion resistance. It is often used in manufacturing material handling equipment provided the aluminum is properly taken care of. Unfortunately, that is often the problem with a material handling structure manufactured from aluminum. Should that aluminum get stretched – which will eventually happen – then the aluminum’s surface layer will oxidize and corrode.

It’s also not uncommon for aluminum to experience water staining with high magnesium-aluminum alloys staining the most. While this doesn’t necessarily degrade the material’s properties, it is an obvious eye-sore that is less than appealing. Just imagine customers seeing water stains on every single aluminum material handling system you have.

Welded structures:

There are plenty of material handling systems that are welded. Unfortunately, these welded structures make the structure’s physical dimensions permanent. Any pre-manufactured or fixed material handling equipment is not easy to adjust or change. In fact, they aren’t designed or supposed to change.

These structures have a role to play for companies like distributors, retailers, or resellers who offer high volumes through a small number of product lines. If these product lines rarely change, then welded structures might work. Unfortunately, business change is commonplace, and welded structures aren’t just expensive to purchase – they’re expensive to fix and replace.

Standard Hardware Store Structures/Shelving:

An argument can be made for hardware store storage and shelving systems. They do play a role in inventory management. However, that role is extremely limited. It’s not uncommon for warehouses to have small shelves that hold small consumables like tape, hammers, nails, scissors, labels, etc. Unfortunately, that’s about it. These systems do not have sufficient load capacity on each shelf which means weight distribution across that shelf is very limited and extremely problematic.

Wooden Structures:

While rarely used, some companies create material handling equipment, workbenches, and workstations out of wood. Unfortunately, this is neither a good material nor a stable material to withstand the heavy loads and repeated use so common in warehouses and production shop floors. Gradually, over time, wood rots, especially when it’s exposed to humidity. As the rot propagates, the wood degrades even further and becomes weaker until eventually, it cracks or breaks. Even in a temperature-controlled warehouse, wood shelving is not a long-term viable solution.
Modular Material Handling Solutions Check all the Boxes
Companies nowadays have multiple concerns. It’s not just about making a good product, building a brand, and keeping customers. While each of these is important, there are other issues today’s companies are starting to take more seriously. Fortunately, a modular material handling system can address all these issues and more.

Ergonomic and Safe Solution

Employee absences due to work injuries are extremely expensive. The typical manufacturer covers $1,000.00 of additional costs every day an employee is injured. When employers adopt ergonomic principles, it immediately has an impact on employee engagement. Their efficiency, productivity, and attendance all improve. In return, companies don’t have to cover as many costs for absences due to injury.

For many industries, a modular material handling system is part of their overall ergonomic strategy. These are the companies that will incorporate anti-fatigue matting solutions inside work cells to provide improved impact resistance for employees. When tube and joint solutions are used alongside anti-fatigue matting solutions, then companies can easily adjust and cut both to accommodate the other.

Modular material handling systems are relied upon because their surfaces, corners and the entire structure is clean, free of burs, and void of any sharp edges. This means modular handling systems are not only ergonomic but safe for use.

Inexpensive Solution Compared to Fixed Structures

Companies faced with modifying fixed structure material handling equipment incur substantial costs and delays. Changing or adjusting fixed material handling systems often involves a tremendous amount of labor-intensive and expensive work.

Simply put, modular piping solutions are easier and faster to assemble, require less expertise, and are nowhere near as expensive or take anywhere near as long as having to send fixed structures to subcontractors. These systems can easily be assembled in-house and adjusted in a fraction of the time compared to a fixed structure material handling system.

Easily Recycled – If needed

Modular handling systems aren’t just easier to work with. While having a system that’s easily customized and adaptable is a definite plus, another benefit includes the ease with which modular systems can be recycled. This is but another way for companies to showcase their environmental stewardship.

The piping and square piping is typically made from steel with a polyethylene coating or a highly-scratch-resistant paint coating. Roller tracks are made from steel or Polyvinyl chloride (PVC) plastic. Joints are also made of steel. Finally, the end caps, pipe connectors, and hinge brackets are either made of PVC or other highly-durable plastic. Ultimately, the result is a material handling solution that is scalable, adaptable, affordable, and recyclable.

Designed with Efficiency in Mind

Modular material handling solutions are designed with efficiency and lean concepts in mind. Companies providing these tube and joint systems are well-aware of how businesses need a scalable and modular solution. These structures can be assembled and disassembled in a fraction of the time when compared to other material handling solutions made from other materials. Ultimately, it’s about enabling companies to make their own changes and structures as they see fit.
Choosing the Right Solution
Choosing a material handling system comes down to defining the type of business you run, the customers you serve, and the market or industry you operate in. Manufacturers have an obvious benefit from using modular material handling systems. However, if you are a small retailer, then modular systems aren’t likely to add any benefits or efficiencies. If you’re a business that sells a few product lines and those product lines never change, then fixed structures might be a solution. However, if your business is constantly changing and continuously growing - and if you know first-hand that fixed structure material handling has not worked for you - then modular systems may just be what you need.

An automated guided vehicle (AGV) is a computer-controlled vehicle used to carry or tow materials in a manufacturing facility. In this video, Bruce Buscher, vice-president of Daifuku’s AGV group, explains why AGVs are a great solution for your assembly line and how you can integrate them with your material handling system.

Jerry Collins – a mechanical engineer with 28 years of experience in the automotive industry – uses the pre-production stage as the critical first step to managing future production costs. It’s during this pre-production stage that Jerry uses modular piping systems as a way to layout his production floor and design material handling systems. This reduces costs and makes it easier to modify those handling systems (if needed) once full-scale production starts.

The Origins of Lean Manufacturing
Lean manufacturing can trace its roots back to Henry Ford’s infamous Model T assembly line and the Toyota Production System (TPS) of the early twentieth century. Sometimes referred to as “lean production” or “just-in-time manufacturing”, lean manufacturing focuses on increasing production throughput while controlling costs and minimizing waste.

With lean manufacturing, companies can increase production throughput without sacrificing their cash position or purchasing excessive inventory. Unfortunately, a large number of companies use some lean concepts while never fully implementing others.
Using Modular Piping for a Mocked Assembly Line
Instead of using lean manufacturing principles during the pre-production stage, several companies only adopt lean concepts long after production has started. Unfortunately, this puts them in a read-and-react position where unforeseen changes in product designs force them to make haphazard and extremely costly adjustments. However, Jerry took an entirely different approach.

[caption id="attachment_38531" align="alignnone" width="1000"] A production line simulation using cardboard boxes. Source: Robert Simonis[/caption]

Jerry and his team used modular piping solutions to create a mockup front axle and rear axle assembly line for General Motors. As stated by Jerry, “long before we purchased any equipment, we created a whole facility with modular piping and decided early on how our material handling systems would be structured.” This included using tube and joint systems to create mock machines and equipment in order to create a visual presentation of both on the shop floor.

They also used modular piping to create trolleys to test the transit times between work cells, all the while looking for any possible obstructions. They then created temporary structures in order to simulate how future material handling systems would be positioned beside work cells, equipment, and machinery.
Making Immediate Adjustments within Minutes – Not Days or Weeks
[caption id="attachment_38508" align="alignnone" width="1440"] A dedicated material handling shop will allows you to modify quickly and on spot structures that need adjustments[/caption]

Jerry and his team of engineers chose modular piping solutions during the preproduction stage because of how easily it was to make simple changes. Some of the changes they made to their mock layout took mere minutes, something that is completely impossible to achieve with fixed material handling systems. As Jerry stated, “companies need to plan their material handling systems early on so they can maintain and improve upon their profits margins later.”

Ultimately, the tube and joint solutions replaced all of their larger, fixed-structure material handling frames. According to Jerry, making a single adjustment to their older material handling structures involved sending their heavy-duty racks to “a third party for welding and adjustments which could take weeks and months, whereas if you have a product like Flexpipe, it can be done in an afternoon.”

For Jerry and his team, adopting modular piping systems during the pre-production stage ensured everybody was comfortable with using the solution once production began. So, what are the inherent benefits of using modular piping during the initial pre-production stage?
Adopting Lean Principles in the Pre-Production Stage
Adopting lean concepts in the pre-production stage by using tube and joint systems has three primary benefits. First, it amalgamates the costs associated with laying out the entire production floor for equipment and machinery, while totaling the costs for standing structures, workbenches, shelving, trolleys, flow racks, boards, etc.

This provides companies with a complete picture of their costs. It also allows companies to decide upon how much actual square footage they need for manufacturing. They can avoid the extra costs of leasing/buying too much production space, or conversely, avoid the high costs and delays that come from not having enough production space.

Second, using modular piping solutions in pre-production helps to simplify workflow. Companies have a much easier time choosing which modular piping solutions are needed for all their T-shaped, U-shaped, and S or Z-type work cells. This allows them to maximize the transit times between production work cells, equipment, machinery, and other standing structures. It also helps them choose ideal locations for inventory and part storage.

Third, by adopting tube and joint systems in the pre-production stage, employees are better able to make quick modifications to standing structures and material handling systems once production begins. No more waiting on welding or having to send out heavy-duty racks to third-party suppliers for modifications that may take weeks or months. Instead, with tube and joint systems, the employees can make the changes themselves.

Modular piping is a product designed with lean concepts in mind. Making changes to modular material handling systems is faster, simpler, and far less expensive when compared to fixed-structure systems.
Simple Steps to Using Modular Piping During Pre-production
Again, any company in any industry can use the same approach. It simply comes down to using the following four steps.

1. Use Spaghetti Diagrams to Define Workflow

Spaghetti diagrams allow you to map your workflow so that you have a visual presentation of how physical parts move between part storage, material handling systems, work cells, equipment, and machinery. The goal is to have a sequential process where the parts move naturally and employees aren’t required to walk extremely long distances to move those parts to the next chain in the process.

2. Gather Information About Machinery & Equipment

Defining the physical size of equipment and machinery is an important aspect of maximizing available shop floor space. You’ll need to define the physical dimensions of equipment and machines and visualize how they will be laid out on the shop floor.

3. Define the Number of Material Handling Systems

Once you’ve defined the areas of your shop floor occupied by machinery and equipment, it becomes easy to determine the number of material handling systems you’ll require. To help you in the design of those systems, Flexpipe has created the Flexpipe Creator Extension, an innovative software-based solution that allows you to simplify your designs.

4. Simulate Transit Times

By now, your shop floor should be mocked up with locations for equipment, machinery, standing structures, work cells, and material handling systems. A proactive final step involves simulating transit times between each of these structures to ensure that there is sufficient space for employees to move parts and that the distances they travel aren’t too far.

Flexpipe: Make it Work For You
Flexpipe is an industry leader in tube and joint systems with a strong North American footprint. Long recognized as an innovator, Flexpipe is well-known for its affordable modular piping solutions (30% less expensive) and its customer-centric approach to customer service and after-sales support.

The term Karakuri -or Karakuri Kaizen- is derived from the Japanese word meaning machinery or mechanical device used to assist a process with limited (or no) automated resources. Its origins come from the mechanical dolls in Japan that essentially helped lay the foundations of robotics.

Instead of being controlled by software or a computer, the basis of its functionality lies entirely in the overall design of the device. This can range from the simple use of gravity to the use of springs, weights, pendulums, etc.

Many facilities and operations are coming to the conclusion that mechanical automation is the only way to go, as Karakuri Kaizen can provide advantageous and relatively inexpensive solutions that can improve operational processes. This can be achieved by using the "Kaizen" approach, which is based on the idea that the "Kaizen" approach is the only way to improve productivity and reduce costs.
Example of the use of Karakuri in Lean Manufacturing
Karakuri is one of the many tools associated with Lean concepts and methodology. Using its fundamentals allows you to dive deeper into business process improvement, but from a cost reduction perspective - it will ultimately allow you to find innovative solutions with a smaller budget. This is why Karakuri Kaizen is commonly used in Lean Manufacturing. Consider this example:

Toyota had identified an inefficient process within its automotive assembly line in which operators were pushing their material/tool carts by hand. This was resulting in lost productivity and an overall extended production cycle time. So Toyota developed a Karakuri-style cart that can be mounted on the car's engine. Once a car is finished, a weight is released that allows the cart to move to the next vehicle. Toyota also incorporated a tray with parts placed on the fender that allows operators much easier access to materials and tools. Removing non-value-added steps as Toyota has done will progressively reduce process times and allow your operation to produce more, in less time.

Four benefits of Karakuri in Lean Manufacturing
Taking an approach like Toyota, one of the world's largest automakers, can provide substantial benefits to a facility attempting to move to a more Lean approach. Using Karakuri Kaizen can provide you with the elements necessary to maintain a competitive edge within your industry.

• Cost reduction - As mentioned throughout this article, Karakuri Kaizen enables significant cost reduction in a variety of ways. By reducing production cycle time and lowering automation and overall material costs as processes are optimized, operations will be able to reinvest in themselves more, as their bottom line will be positively impacted.

• Process improvement – In synergy with other Lean concepts, Karakuri reduces the overall cycle time by "automating" the process with a device, instead of relying on manual movement. Like the Toyota example, breaking down the process and locating non-value added steps will help determine which elements would benefit from innovative Karakuri solutions and structures.

• Quality improvement – Process improvement has a direct impact on product improvement. An inefficient production process increases the chances of manufacturing defects and potential errors, so process planning and establishing the most efficient route can only further improve product quality.

• The simplicity of maintenance – Automated systems lead to increased maintenance costs, especially for operations that are almost entirely dependent on their automation. This will usually result in the need for a 24/7 maintenance team in case the system fails - which it inevitably will. Karakuri devices are easy to maintain because of their simplicity and the materials they are made of, so managers don't have to spend a fortune on a new department and team to keep everything running well.

Karakuri Kaizen provides a beneficial foundation and framework that ensures your production system continues to optimize processes and operational flow. If you are looking to improve operational efficiency, Karakuri is an indispensable tool that will improve performance and enhance the bottom line.
The mechanisms used to make a karakuri
[caption id="attachment_37825" align="aligncenter" width="871"] Le système de levier est un mécanisme couramment utilisée.[/caption]
1- The lever is one of the most important inventions of karakuri style

The lever system is a commonly used structure, especially in simple devices. It allows for easy lifting of heavy objects, as it involves a bar moving on a fixed point (the fulcrum) when a force is applied to it.
2- Inclined planes

Inclines are everywhere - they are almost impossible to avoid. Sloping roads, hills and ramps are examples of inclines we encounter every day. The incline is a simple but effective way to transport an object on an elevated surface or to use gravity to your advantage to send an object down.

 
3- The winch

A winch is a device that creates or releases tension on a rope or wire to adjust its length, usually by means of a crank. Winches are commonly used in tugboats, fishing boats, cranes and even rescue helicopters.

 
4- The spring

The spring is another element frequently used in everyday life by many people. It can be found in a mattress, an enclosure and even in a mouse trap. Springs are made of steel and are available in a variety of designs, including the coil spring. Springs store mechanical energy and release it when a restraining force is removed. One can easily picture a spring when thinking of a retractable pen.

 
5- Magnetic energy

It is said that opposites attract - at least that is the case with magnets. Magnets allow for attraction or repulsion and are another commonly used karakuri-style structure, especially in refrigerators and freezers.

 
6- The pulley system

Like the other simple systems on this list, the pulley system was a revolutionary idea used in all types of industries. The pulley involves the use of a rope or cord around a rim, which allows for the transmission of energy and motion. It is especially useful when lifting heavy objects; in this regard, the more pulleys added to the system, the more weight is distributed among them, making it easier for the user.

 
7- Pascal's principle

In the visual below, Pascal's principle demonstrates that a force applied at one point to a liquid in a container is accompanied by equal pressure in all directions. F1 pushes down on A1 in a smaller, more condensed area, but this equal force and pressure will be exerted in A2 and up to F2, thus illustrating the principle.

This principle is widely used in many pieces of equipment such as hydraulic systems, car brakes, barber chairs and a variety of equipment.

To many of those who have studied supply chain and the concepts pertaining to lean methodology, you probably view the layout of a warehouse or manufacturing center through a different set of lenses. You are able to visualize how inefficient processes are reducing output, ultimately leading to an uptick in money and time. This only hinders a facility’s ability to further expand and grow up on itself, but as operation and project managers are aware of - sometimes getting everyone on board with the “no waste” mindset, it is easier said than done!

[caption id="attachment_38004" align="alignnone" width="1195"] A hole has been made in the HDPE of this modular table to facilitate the accessibility of small frequently used parts.[/caption]

This is a common question that operations will ask themselves. How can I communicate, establish, and sustain a continuous improvement culture? How do I incorporate lean thinking into the mindset of all of my team’s daily tasks? This is where there is a difference between those on the floor and those in the office. While those in the office are familiar with the terminology and lean concepts, those on the floor do not always look at everyday tasks in the same manner. It is more or less viewed as “get the job done” as opposed to “how can we make this better?”.

[caption id="attachment_37603" align="alignnone" width="1440"] This multi-storage structure was designed from scratch by Chris in collaboration with the production team[/caption]

The question of “how can we make this better?” is not one that many associates on the floor will ask themselves as they believe management will handle problem-solving or, more often than not, they are not asked for input or ideas. This is the mindset that we seek to eradicate. Whenever there is an inefficient process, it should become obvious to everyone within the facility as to what aspects of the process are taking the most time and ultimately leading to wasteful activities. This is where management can be a bit blind as they think this task is rather difficult to achieve, but there is a saving grace and a middle man between management and associates - the continuous improvement technician.
How the Continuous Improvement Technician Can be a Vital Asset to Continuous Improvement
No one can communicate or fix a problem like the continuous improvement technician, considering that all day long he deals with one thing - maintenance. While those in management often look at problems from an analytical and theoretical perspective, the continuous improvement technician has key insight as to whether a goal is actually obtainable in order to make it a reality.

[caption id="attachment_37575" align="alignnone" width="1440"] This structure has been optimized to make room for an easily accessible wheelie bin[/caption]

More often than not the continuous improvement technician also has not gone to school or studied lean concepts and doesn’t look at it through the same lens, but rather through his own experience of working with machinery and equipment. The continuous improvement technician focuses on fixing things and making them better solely for the purposes of making things easier on himself and those on the floor as well as mitigating the risk of a future failure. Who wants to fix something over and over again when you could do it correctly the first time, right?

In an interview with President Container’s continuous improvement technician, Chris Pryce, we asked him to provide some key insight on how he goes about continuous improvement and instilling it among those who participate in the daily activities and work.

He started off by mentioning the first step in getting everyone on board is simply asking for their input. Whenever a team member has an idea, they have “kaizen suggestion sheets” available for the employees to fill out. This can be with any idea that they may have on making a process more efficient or better, considering much like the continuous improvement technician, they are the ones working with the equipment on a daily basis. These “kaizen suggestion sheets” are essentially the doorway into allowing associates on the floor to begin the process of eliminating the mindset of “just get the job done” to “how can I make this better?”. Ideas are then passed onto management to see if they are able to be theoretically conducted.

[caption id="attachment_37460" align="alignnone" width="1440"] The continuous improvement suggestion box.[/caption]

Communicating these needs are important but usually needs to be proven in a statistical manner. One of the most prominent questions that arise are ones such as “how will this cut cycle time?” or “how can this reduce waste while also increasing output?”. Usually, a continuous improvement team will run an analysis on the processes at hand and can aid in helping get an overall view of the statistical data needed to persuade management. Once this process is complete, it can then be passed onto maintenance to make it a reality.

[caption id="attachment_37595" align="alignnone" width="1440"] Chris Pryce, the continuous improvement technician with his colleague from the continuous improvement team Mana Sanchez[/caption]

Chris will then use his experience to transform the idea into an actual process on the floor, in which continuous improvement teams will then observe the results and document how the process either improved or what drawbacks may still be remaining. To simplify things, here is a breakdown of the process at hand in which was conducted in six easy steps:

1. Identify a problem or opportunity - This is where the kaizen suggestion sheets come into play. Utilizing these can be advantageous in the sense that they aid with the development of continuous improvement ideas. Allowing associates and employees to brainstorm and come up with concepts that can help the company is the first step in moving toward a lean culture.

2. Analyze the process - Once the sheets are passed onto management, this is where the continuous improvement team and management analyze the processes at hand along with the potential idea. This is conducted in a variety of ways, in which the gauge of what needs to be improved depends on the hindrance at hand.

3. Develop an optimal solution - This is where the brainstorming comes into play as to how to potentially implement the solution. Tools, equipment, materials, and manpower are roped into the equation of feasibility. Once all boxes are checked, it’s time to implement the solution.

4. Implement the solution - The continuous improvement technician, Chris, will then implement the solution with the tools and equipment at hand. He will redesign a process, implement a new piece of equipment, or any other idea that was presented.

5. Study the results and adjust - The trial period after implementation will be analyzed and studied by the continuous improvement team and management. This is key because it allows for statistical data to be presented to further demonstrate how well the idea is working.

6. Standardize the solution - If the idea works appropriately and is a success, the idea will then be implemented to all processes that require it and become a standardized practice of the company.

Without the collaboration between associates, maintenance, and management, none of this could have become a reality. This is where instilling continuous improvement culture is by far one of the most important attributes to iterate within any setting. Not all brilliant ideas need to come from the top. In fact, a lot of them come from the individuals working with the process or equipment the most. To put this into perspective, think about your daily tasks. How many times a day do you think of how you could make a task easier, simpler, or much more efficient? Being involved in a process can provide key insight on how to make it better.

[caption id="attachment_37599" align="alignnone" width="1440"] Clearly, this hyper-personalized structure requires effective collaboration and communication.[/caption]
Getting Everyone On Board with a Continuous Improvement Culture
As mentioned previously, some things are easier said than done - but it never hurts to try. There are a lot of companies that incorporate lean methodology and continuous improvement into their culture, and one of the most important advantages that they have instilled within their operations is that every idea matters/counts. It gets everyone thinking about how to further better operations as opposed to having an inner circle at the top trickling down every idea. To begin the process of implementing a continuous improvement culture, start out with something simple such as asking employees for recommendations on processes. Issue out sheets like Chris does and seek feedback on making aspects of the company better. Valuing the input of your associates as well as hearing feedback will allow you to start your operation’s journey from “get it done” to “let’s make it better”.

More often than not, companies are seeking “workarounds” and low-cost continuous improvement projects that present results. This is where utilizing Flexpipe can be a vital asset to your continuous improvement projects, as Flexpipe is able to construct low-cost solutions. Flexpipe allows you to model a pipe and joint modular structure and visualize how it would look and work even before being implemented. Utilizing Flexpipe can open doors to solutions that maybe did not seem possible without a substantial amount of capital to invest, but constructing these devices are both low cost and innovative, thus further driving your continuous improvement culture.

Continuous flow is one of the five principles of lean management, which aims to eliminate waste in production lines. By eliminating wasted time, it helps employees work more efficiently on a daily basis.

Engineer David Nobert is an expert on this subject. As a long-time Service Manager in Createch’s Operational Performance Improvement team, he has supported companies wishing to optimize their operational processes. In this video, he introduces you to the concept.



 
What is continuous flow?
Continuous flow is the process of creating an uninterrupted sequence of activities in the production line, which helps reduce downtime and waiting, which are both major sources of waste.

Essentially, this principle aims to set up manufacturing cells comprised of machines or workstations that produce one part at a time, step by step.

To be effective, continuous flow must take each of the three types of flow into consideration:

1– The flow of materials

2– The flow of information

3– The flow of human resources

Interruptions or slowdowns in any of these flows, such as an employee having to wait unnecessarily for parts, can hinder the entire production line.

Take a look at this video in which Paul Akers explains to us what is flow, what it does when it is not continuous and give us some tricks on give us some tricks on how to find solutions to bottlenecks.


How to improve performance with continuous flow
Continuous flow has several advantages. By eliminating downtime, it enables you to get goods to customers faster. This reduces your warehousing costs because you’ll require less space to store your products.

In addition, you can detect defects in the produced parts in advance. In fact, your employees can practically spot problems at the source before they become too significant and affect the entire production line, which improves your overall productivity and lowers your production costs.

Continuous flow is also known to increase versatility of your resources. As they will be capable of performing a large number of different tasks, they can deal with incidents more effectively.
How to ensure continuous flow is efficient
Since overhandling are the enemies of continuous flow, you must eliminate them from your process at all costs. Ideally, materials should circulate properly in your factory in order to prevent workstation supply delays.

When designing the continuous flow, also take employee feedback into account. Your employees are in the best position to put the theoretical principles of lean management into practice.

When designing work cells, give preference to U-cells. In addition to facilitating the supply of parts, this configuration provides notable space-saving and improves communication and teamwork between workers.

For a noticeable improvement in productivity, also make sure that your resources have all of their tools at their fingertips, and not stored away in drawers or chests.

Lastly, do not hesitate to assign an experienced employee or a team leader to each work unit. They will help their colleagues develop new skills, while giving them the desired pace of production.
Lean principles
Continuous flow will obviously help you reduce your waste. However, to completely eliminate the non-value-added activities of your production processes, you’ll need to apply each of the  five fundamental principles of lean:

Define the value.
Map the value stream.
Create and maintain a continuous flow.
Establish pull (which means that the production of the product or service is triggered by a customer need).
Seek perfection by constantly improving.

Lean is much more than a work methodology. It will generate a real change of mindset within your facilities. You’ll evolve from an individualistic culture to a collaborative culture for the greater good of your organization!

WHAT CAN FLEXPIPE DO TO OPTIMIZE YOUR PLANT EFFICIENCY?
Flexpipe Modular industrial pipe racking system can help you with implementing continuous improvement principles. Your team’s creativity can result in a 10% increase in productivity per year. It has been a proven system for more than 50 years now.

As a manufacturer, one of your main advantages is to eliminate wastes, in other words, actions that are unnecessary and provide no added value. Shadow boards are an excellent means of implementing continuous improvement principles because their purpose is to eliminate the 8 manufacturing wastes. This article will give you tips on how to sort your tools and create order so you can efficiently carry out daily tasks, regardless of the nature of your work.

[cta id="47713"]

According to the 5 S method
According to the 5S method, shadow boards are commonly used to visually manage tools that are frequently utilized during the day. It's a very appealing approach as you can apply it to almost any environment!
A shadow board is a visual method of stocking items by means of a filled-in contour of every one of them in a colored backdrop to show where the tool should be put back after each use.
It's in the second S: SET IN ORDER or "Seiton" in Japanese, that the shadow boards come in. The exact meaning of this term is to lay out all objects and put each one in its place. Establishing a designated location for every tool or piece of equipment will help you find what you need when you need it.

A place for everything and everything in its place
You can increase efficiency by significantly reducing wastes that provide no added value, such as time lost looking for a screwdriver a broom or a pair of scissors.
Good to know - For optimal visual management of your tools and parts, here are the 3 essential elements of a shadow board:

ID tag
Color code
Tool's shadow

Typically, a pegboard is the shadow board's foundation on which is painted the contour or shadow of the item to be hooked on the board. Shadow boards are an efficient way to create a visual impact thanks to the colored background. You can put tools or production items on them, such as dies or prototypes, for example.

 
The shadow board above is a kitting cart that one of our customers uses with its supplier to avoid overpackaging and waste materials on the production line.

By sending these boxes back to the supplier, the latter can simply insert all the items ordered by the customer in them again without having to restock packaging materials himself.

In addition to being environmentally friendly, this method prevents the supplier from forgetting any items and makes order prep easier. The color coding calls attention to missing parts.
 
Make your own shadow board

3 simple steps to build a shadow board to meet your needs
This section of the article will provide you with tips as well as steps involved in building the type of shadow board that will be most effective and profitable for your business needs.

Step 1 - decide which tools you need
First, gather all your tools to decide which ones will go on the shadow board. To help you choose those needed to carry out your tasks, think of the setting in a hospital's operating room. A surgeon should never have more than what is required to operate on the patient nor have to hunt around for a specific scalpel!

Tip : If you have trouble figuring out what you use in a typical workday, put in a box all the tools and parts that you utilize as the day progresses. As such, you'll have a better idea of what's essential in your workstation.

To avoid unnecessary steps, you should always position your tools as close as possible in your workstation. Normally, these would correspond to those which you use within the hour or during the workday. In an office setting, the same principle applies: Items that are regularly utilized should be placed on the desk.
Use this chart to decide if the tool in question should go on a shadow board or not.

Step 2 - Decide on the type of panel and its location
Once you've decided on the tools that should be within reach, now it's time to choose the material. The number of items and the shadow board's location is two determining factors at this step in the process.
Here are some examples of our customer's shadow boards as a source of inspiration. Some chose to use materials they already had on hand, while others opted for laser cut-outs in foam panels.

If this type of shadow board interests you, we highly recommend its manufacturer - who also happens to be one of our suppliers: OSAAP AMERICA.
This Maine-based company, in the US, produce boards made of various types of foam, most with laser cut-outs for added precision. Curious to see how they do it? Take a look.
 
Types of pegboard
HIGH DENSITY POLYETHYLENE (HDPE)
High density polyethylene is a 1/4 inch thick white plastic surface. This type of material is rigid, the high density of this product makes it shatterproof and ultra durable. This surface is easily cut with a decent saw. For more information, refer to product D-PEGW-481/4 on the online store.

MASONITE
Masonite pegboards are the most common on the market. They can generally be found in hardware stores or home improvement big-box stores. The panels are available at low cost and have either 1/8-inch holes or 1/4-inch holes for more robust use.
Masonite panels are not intended to hold heavy tools, such as drills. Doing so would cause the panel to warp and eventually rip. Also, with time, the holes in the panels can sustain damage from frequent hook changes.

The image below shows various types of hooks that you can use to hang your tools

Tip: At Flexpipe, we simply use screws with bolts for added strength.
 

METAL
Long-lasting, metal is easy to clean and is one of the most solid materials on the market. It also gives the pegboard a stylish look. It's worth keeping in mind that metal boards are the most expensive option and their weight makes them difficult to buy in larger sizes.
Additionally, if the air is humid, be sure to use stainless steel to avoid rust issues. Finally, remember that metal conducts electricity, so take precautionary measures to provide your employees with a safe work environment.

ACRYLIC
Plastic or polymer acrylic pegboards offer unparalleled versatility and reliability. They are much lighter than their Masonite and metal counterparts.
Their durability is unbeatable, given that they are rustproof, will not crack or warp. This type of board can withstand heavy loads.

Each type of material has its advantages and drawbacks; evaluate them all to find the best for your needs.

You can also make your shadow boards out of foam if, for example, you need to store or handle fragile parts a production line. You'll notice that most of these shadow boards are placed on a wheel-mounted cart or rack.
If you decide to build a foam shadow board, there are several grades of foam from which to choose. On the other hand, the more the foam is porous, the more difficult it will be to cut, as Ethafoam for example. There are greater risks of it disintegrating where the knife penetrated it, consequently shortening its life span.


 
Type-A foam panels, such as Crosslink, are of better quality thanks to their high density. This type of foam will protect fragile parts more effectively.
You can also use materials you already have on hand in your plant to build your shadow board. Some of our customers used MDF panels, whereas others decided on steel panels. A little creativity mixed with a desire to reuse existing materials can give pretty impressive results!
Tip: Regardless of the type of material you choose for the shadow board, we suggest dividing it into sections. It will be much easier to alter only a portion of the entire board, instead of the whole thing, should you have to move tools around.
 
Step 3 - draw the outline of your tools
To begin, set your tools on the panel to use up space in the most optimal way. This task may be painstaking as you'll have to try a few configurations before finding the ideal one.

Be sure to properly align all tools. We recommend grouping them by families: adjustable wrenches, hammers, screwdrivers, drill bits, etc. After, draw the tools' outlines at their designated location on the panel.
To conclude, all that's left to do is to place the hooks and hang your tools. Take a picture of the final product and show your project to the rest of the team so everyone can use this work method!
 
Benefits of using a shadow board
In short, implementing the 5S system will have a positive effect on your operations, such as:

Reduced costs as you'll only use the tools and material that are necessary
Improved quality
A more secure work environment
Increased productivity
Increased employee satisfaction regarding their designated tasks

Whether the shadow board is in an office setting or for workstations in the production line, everyone will come out a winner. Don't wait another second before trying one!

If you’re thinking of introducing lean manufacturing on the shop floor, you may have noticed that some production employees are hesitant to shift their habits. For example, they may say that their way of doing things has always generated good results or that the proposed modifications don’t apply to their current situation. Rest assured, your predicament is common. Most businesses in the manufacturing sector have faced this problem at one time or another. Thankfully, there are many methods to overcome resistance to change.

Estimated reading time: 8 minutes

1 – Explain the reasons behind the change

Begin by stating the motive(s) for the transition to your team. Some ideas could be to be more competitive, to face growing demand, or to serve your customers better. However, avoid basing your explanations solely on profitability. If the proposed changes are purely for financial reasons, you risk not getting everyone on board.
2 – Call upon an external training facilitator

Before beginning the Lean training process, plan to have the appropriate resources. Smaller businesses often retain the services of an external instructor. In the eyes of the staff, he can lend credibility to the process thanks to his professional expertise.

If you do use an external consultant, be sure the person overseeing the Lean process within your organization (the Lean sensei) works with the trainer to provide insight into the company’s situation. The sensei can also guide the consultant’s presentation and play a part in the discussions.
3 – Provide Basic Lean training to all personnel
[caption id="attachment_17846" align="alignnone" width="814"] Flexpipe assists in training while visiting an Adidas Plant in China.[/caption]

Before engaging in Lean practices, your employees will need to receive basic training on the Lean culture to understand it and speak its unique language. At the end of the process, they should be familiar with founding principles such as 5S and various types of wastes, and knowing what added value does and doesn’t consist of.

To win over those who are most reticent, trainers can show testimonials, pictures, and videos of companies who have gone through Lean improvements. Doing so is a lighter and more user-friendly means of convincing instead of text-heavy presentations that don’t always engage those in attendance.
4 – Visit other plants and speak with their employees
[caption id="attachment_17840" align="alignnone" width="814"] Flexpipe visited Lumenpulse in Longueuil, Québec.[/caption]

[caption id="attachment_17843" align="alignnone" width="814"] Flexpipe visited Lumenpulse in Longueuil, Québec.[/caption]

To convince employees of the benefits of the upcoming changes, suggest that they visit non-competitive plants, which recently undertook the same process as yours. If there is no one you can contact, search on LinkedIn or call organizations that do tours in Lean facilities, such as the Association for Manufacturing Excellence, the Gemba Academy, the Lean Enterprise Institute, or the Mouvement Québécois de la qualité.

While it may be challenging to get employees on-site, those who do go will become your most valued spokespeople. Why? Because they will have seen the transformation for themselves and, most importantly, talked with employees who carry out similar tasks. The latter will be able to explain how they experienced the change and the advantages of working in a Lean environment. Such discussions can reassure those who are particularly hesitant regarding the proposed adjustments.

Our team at Flexpipe recently toured the BRP snowmobile plant. After the visit, our five production team leaders exclaimed, “Wow, the production floor is open, airy, and clean. We would love to work in an environment like this.”
5 – Start with small, simple changes
[caption id="attachment_17858" align="alignnone" width="814"] Employees are showing their simple and resourceful self-constructed Shadow Board[/caption]

To display the physical benefits of the ongoing change, choose a high-visibility work cell which will serve as a model. This space will be the designated location to implement your first projects.

Avoid beginning with lengthy, costly, and complicated undertakings. Instead, make small tweaks with a big payoff, such as improving a substandard workstation. Once you’ve finished your first project, ask your employees to examine the issue that has been solved—they’ll have the proof right before their eyes.

Starting small means, you’ll be able to show the results to your team quickly and reduce the risk of failure.
6 – Ask employees to pitch ideas
[caption id="attachment_17834" align="alignnone" width="814"] Improvement Submission Board at Flexpipe.[/caption]

[caption id="attachment_18007" align="alignnone" width="814"] Improvement Submissions with a visual explanation.[/caption]

Getting employees involved is the surest way to overcome resistance to change—even if you provide Lean training. You will need to make them understand that the ownership of the transformations doesn’t solely rely on 1 or 2 people; instead, it’s company-wide ownership. That way, a Lean culture will permeate all echelons of the business.

One of the best ways to have team members participate in the transition is to gather their ideas by using a suggestion box or board. Your supervisors and those spearheading the improvement process can also help employees make recommendations on an ongoing basis.

Responding to all suggestions quickly is a robust approach to show that you open to change and innovation.
7 – Encourage employees to plan the entire project

While having ideas is undoubtedly a good thing, it’s even better to explore them. Encourage employees to lend a hand in crafting the solution by having them sketch out a problematic element in their environment and what could correct it.

If needed, the person leading the improvement process can help the staff realize and refine their ideas. Additionally, he could suggest a brainstorming session among team members to generate further options.
8 – Ask employees to help implement an idea

Once you’ve collected the various concepts and encouraged employees to play a role in devising the solution, why not ask them to continue the creation process by, for example, having them design their new lean manufacturing workstation? Besides feeling proud of his accomplishment, an employee can improve upon his workstation again in the future according to the company’s unique requirements, when need be.

One way to make ideas come to life more efficiently is to have tools and necessary materials on hand. A moonshine shop can be an exciting option to provide a creative setting.
9 – Celebrate the victories—and the defeats—resulting from the change

[caption id="attachment_17864" align="alignnone" width="814"] All the Flexpipe employees at the MPA Trade Show in Montreal.[/caption]

Your organization should celebrate both the highs and lows related to the change process. Some businesses offer a reward such as t-shirts, corporate items, or gift cards to participants. The gifts need not be expensive; they’re meant to recognize the employees’ efforts and encourage them to continue the Lean transformation endeavor.
10 – Keeping flexibility and agility in mind while recruiting
Even with the best intentions, sometimes it’s difficult to overcome resistance to change in some employees. When recruiting, make sure to emphasize flexibility and agility. Ask candidates to give you examples of changes they’ve gone through in past jobs and how they reacted to it—beware of those with a hardline stance or who seem insincere.

WHAT CAN FLEXPIPE DO TO OPTIMIZE YOUR PLANT EFFICIENCY?

Flexpipe modular industrial pipe racking system can help you with implementing continuous improvement principles. Your team’s creativity can result in a 10% increase in productivity per year. It has been a proven system for more than 50 years now, which allows to reduce the 8 manufacturing wastes.

The time has come for many North American manufacturers to get back to work. The situation will obviously not be the same as it was before. Ways of doing things will have to be adjusted. In the coming weeks, plants will be implementing a host of new measures to comply with new government rules, particularly in terms of health and safety. If this is the case for your company, here are nine tips, based on the principles of continuous improvement (lean manufacturing) that will help you prepare for a safe return to work.

1– Distancing your employees from each other
It's not always easy to maintain the physical distance of 2-meter on an assembly line. Employees often work very close to each other and have little room to maneuver.

By using modular aluminum panels or those manufactured by Flexpipe, these new physical constraints can be more easily met. For example, you can add acrylic panels between employees working opposite each other or a tubular panel, with an acrylic interior, for employees working side by side. Acrylic is currently hard to find; you can therefore also hang mica canvases with eyelets on your structure or workstation that are attached to a steel or tubular frame.

In the event that you cannot modify your existing workstation, install large panels, either wheeled or fixed, between employees instead. Flexpipe offers several such modular panels. Why should you choose Flexpipe? You can take them down and reuse them to make a cart, for example, when the pandemic subsides.

[caption id="attachment_18908" align="alignnone" width="814"] Here are dividing panels for working side by side[/caption]

[caption id="attachment_18938" align="alignnone" width="814"] Here are dividing panels for face to face work.[/caption]

[caption id="attachment_18887" align="alignnone" width="814"] Here is a separator panel that will help create a distance between employees.[/caption]

 
2– Transforming your equipment into mobile units
Are your workstations and equipment on wheels? If they are not, take advantage of the current context to install them. It is an inexpensive investment that helps you increase the mobility of your work environment so that you can more easily comply with the rules of physical distancing. There are also various braking systems, such as foot brakes or total locks, to stabilize workstations.

For example, at Flexpipe, we have relocated part of the staff in our building reserved for assembly to our warehouse. This operation, aimed at reducing contact between employees, was simple to carry out since all our workstations are equipped with four- to six-swivel wheels.

[caption id="attachment_19443" align="alignnone" width="814"] Point of use tooling (POUT) with 4 swivels caster with total lock brake[/caption]

[caption id="attachment_19449" align="alignnone" width="814"] Steel Tool cabinet that was put on caster[/caption]
3– Strengthening your 5S program
Even though 5S can increase productivity and reduce the risk of accidents, it will also be very useful when disinfecting work tools.

By using the 5S program, you will clean up your workstations to leave only the tools your workforce uses regularly. For example, at Flexpipe, an employee disinfects work tools, but also door handles and kitchen equipment three times a day. Thanks to the 5S program, our disinfection manager is much more efficient because he does not waste time disinfecting unused tools.

Already have a 5S program in place? Remind your staff about the importance of being rigorous, especially during a pandemic.

[caption id="attachment_19453" align="alignnone" width="814"] The 5S system facilitates the disinfection of workstations.[/caption]

See how the facilitators of hygiene measures apply in the medical sector.
4– Reviewing your work procedures and standards
While your plant is reopening, why not take advantage to review your work procedures and standards in order to avoid, as much as possible, the sharing of tools and equipment? In addition to improving your processes, you will provide a safer environment for your employees.

Over the next few weeks, you may have to operate with limited staff. If you have never done so, don't hesitate to reassign one of your temporarily laid-off employees to update your work procedures and standards, especially if you are eligible for government assistance for businesses.

5– Using visual cues
Visual cues are quick and easy to set up. Using different coloured tape, draw lines on the ground to clearly delineate the corridors and different work areas in your plant. For example, at Flexpipe, we have created one-way corridors to prevent people from crossing each other.

Don't hesitate to use vinyl that sticks to the floor to clearly mark the 2-meter distance your staff must respect, especially in busy areas such as the cafeteria.
6– Managing the flow of materials to work cells
Consider identifying the materials, raw materials, work in process, and finished products within each work cell in your plant to limit contact between your employees and other stakeholders.

For example, use flow racks for your hardware parts. With this system, the inventory handler brings the parts to the back and the assembler takes them from the front, without any contact between the two.

Apply the same principle to your shipments. Clearly define the area in which the products are to be picked up, at a certain distance from your workspace.

7– Limiting unnecessary travel
The pandemic is one of the best reasons to encourage your employees to stay at their workstations. Indeed, unnecessary movement and travel is one of the most important wastes in value-added production because it does not add value.

At Flexpipe, we have put in place a policy to reduce the number of people walking around the plant.

Our assemblers receive their parts from a single employee who goes around the workstations with a trolley. If, for any reason (defective part, lost part, etc.), one of our assemblers needs new parts, they must stay at their station and notify their supervisor. To avoid a recurrence, the employee is asked to describe as accurately as possible the problem they just encountered while waiting for the new parts. Once the problem has been described, another employee will take over the task of finding a solution to the problem.

 
8– Setting up POUTs for sanitary facilities
Like most factories, you have probably purchased sanitary equipment (gloves, masks, disinfectants, etc.). To improve efficiency, set up Points of Use Tooling (POUTs), which are small workstations in which sanitary equipment is neatly stored and easily accessible, at strategic points in your plant.

Use this opportunity to post the company's policies on COVID-19 at each POUT.

9– Deliver elevated quality standards right from the beginning
Production defects are one of the most common wastes in value-added production. Especially in the context of coronavirus, positively encourage your employees to do quality work right from the beginning.

Why should you do this? Because a poorly assembled part is manipulated by many employees who will try to discover the problem and fix it. In contrast, impeccable work involves fewer people and less travel. You will limit the risks of propagation while increasing your productivity.

Circular manufacturing is a system for maximizing efficiency and reducing waste in a manufacturing site.

In this video, Robert Simonis, principal consultant at KCE Consulting, explains the four rules of this lean technique and how they can improve the flow of any work process.

Rule No. 1: The process should begin and end in the same location
For optimal flow, the work process should always end near the spot where it began. This ensures that as soon as an employee finishes a task, they can start the next one without wasting any time traveling from one end of the warehouse to the other. This usually means that the process will be laid out in a U shape.

[caption id="attachment_26415" align="alignnone" width="615"] People on the production line, the workstations, and the equipment should be organized to optimize the flow and minimize waste so that productivity can be maximized. Source: Assembly Mag and Bosch Rexroth Corp[/caption]

By contrast, a process that follows a straight line—while it might seem logical for the flow of materials—forces operators and material handlers to make a return trip to their starting point at the end of each cycle, which is a form of waste.
Rule No. 2: The process should not intersect
When a process starts and ends in the same location, there’s a risk that people or materials will cross paths somewhere along the line. It’s important to make sure that doesn’t happen, as much for efficiency as for safety reasons.

[caption id="attachment_26397" align="alignnone" width="1875"] Material handlers travel the width of the building, then return empty. Source: Robert Simonis[/caption]

[caption id="attachment_26394" align="alignnone" width="1897"] Empowered teams focused on optimizing their value stream. Source: Robert Simonis[/caption]

Wherever people or objects cross each other, slowdowns, bottlenecks, and accidents can happen—just like at an intersection. An intersecting production line also creates confusion about which direction to take, resulting in lost time and misplaced materials.

Creating a clear, unobstructed path forward is a key part of optimizing flow.
Rule No. 3: Make the circle smaller
Whereas the first two rules of circular manufacturing create a more logical process for operators, the third rule helps cut motion waste and transportation waste.

Imagine the production process as a circle; the larger the circle, the greater the distance employees have to travel from one point to another.

When work cells are placed close together and frequently used tools and parts are within reach, employees will spend less time walking and more time performing the tasks that add value to the end product.
Rule No. 4: The process should be circular, but not circle-shaped
Once the first three rules of circular manufacturing are implemented, the production line will not be shaped like a circle. Rather, the process will be U-shaped or resemble some variation of this form (for instance, a serpentine or Christmas tree pattern).

Unlike a circle, these shapes create a short distance from one side of the path to the other, reducing total travel time.
How does circular manufacturing help with line balancing?
One of the main advantages of a circular configuration over a straight line is that it allows for greater flexibility when it comes to line balancing (leveling the workload across different stations on a production line to prevent bottlenecks).

A straight production line can be balanced only by redistributing tasks to stations to the right or left. But with a circular line, process steps can be redistributed to cells behind as well as to the right or left, providing more options for improving flow.
How does circular manufacturing benefit employees?
Employees who are accustomed to the straight-line model might be reluctant to try a circular workflow because it appears to be more demanding.

Rather than remaining at one station where they repeat the same task over and over, employees on a circular line switch between different tasks and operate more than one machine.

While this does require operators to learn new skills, the benefits are clear. Moving around and using different muscles is more ergonomically sound than repeating the same motion all day long, so operators tend to experience less fatigue and fewer injuries. Being involved with different stages of production also helps operators feel more engaged with their work.

Looking for evidence of the four rules of circular manufacturing—a workflow that starts and ends close together, does not intersect, reduces travel distances, and is circular but not a circle—is an excellent way to quickly assess whether any manufacturing site is set up efficiently and safely.
