Kitting Carts: An Essential Lean Manufacturing Tool

In lean manufacturing environments, Flexpipe kitting carts ensure production employees have the necessary tools, consumables, bill-of-materials (BOM), work-order instructions, and work-in-process (WIP) parts needed to complete a work order or work task. Mobile Flexpipe kitting carts are critical to ensure that workflow remains uninterrupted and that production employee wait times are minimized.
Manufacturers with welded or fixed-structure kitting carts cannot modify them without significant costs and incurring long refurbishing lead times. Given the constantly changing requirements in lean manufacturing – where continuous improvements and never-ending changes thrive – a low-cost, modular, and scalable Flexpipe kitting cart can quickly be adjusted or modified as needed.
So, why are Flexpipe kitting carts a difference maker in lean manufacturing environments?
Understanding Flexpipe Kitting Carts:
A common misconception is that kitting carts are the same as material handling carts. Yes, both transport materials. However, a modular and scalable Flexpipe kitting cart is specifically designed to carry work-order-specific materials and consumables, and a material handling cart or trolley is meant for transporting general production materials or finished goods.
While somewhat like lean manufacturing carts or material handling carts, Flexpipe kitting carts are designed for production employees because they provide the cut-to-length materials, ready-to-assemble parts, the tools, and the instructions needed to complete a specific production work order or work task. Flexpipe kitting carts can be specifically designed, assembled, and disassembled to adjust to the constantly changing requirements in lean manufacturing.
The best way to think about lean manufacturing carts and material handling carts is to think about how they move materials throughout a company’s manufacturing facility. They can move finished goods or raw materials. A kitting cart contains materials and parts specifically “kitted” so that the production employee within the workstation can complete his or her work task.
The kitting cart might include the raw materials, a special Allen key for assembly, work order instructions, fastener packs, subcomponent parts, and anything else needed for the production employee in their workstation.
Benefits of Using Flexpipe Kitting Carts
A Flexpipe kitting cart can act as an error-proofing, Poka-Yoke solution for production employees. If any raw materials, consumables, fasteners, or other critical parts needed to complete the work task or work order are missing, then the production employee can’t finish their work order. In the most advanced lean manufacturing environments, a production employee will often check to make sure the kitting cart has the proper allotment of materials and parts to finish the work order.
Flexpipe kitting carts can be configured with simple solutions like Kaizen foam inserts to ensure the proper placement of tools. They can be customized with ESD-compliant materials and decking materials so that only the right-sized parts, materials, and consumables can be placed inside the kitting cart.
Flexpipe kitting carts are all about efficiency. They ensure that production employees in lean manufacturing workstations never have to leave to get parts, raw materials, tools, or much-needed instructions. Everything they need to complete the work order should be included in the kitting cart.
Flexpipe kitting carts enhance workflow and dramatically improve productivity. They ensure an uninterrupted flow of work by allowing production employees to focus on their work tasks. No time is wasted searching aimlessly for instructions, fasteners, work orders, raw materials, consumables, or parts. Everything is included in the kitting cart to reduce search times and limit motion waste.
An often-overlooked benefit is how kitting carts ensure a clean, well-maintained workstation. Instead of having materials, consumables, instructions, work order information, and fasteners strewn about the workstation, they’re all properly placed within the Flexpipe kitting cart. They ensure that production employees properly adhere to essential 5S principles of workspace organization.
Ultimately, a Flexpipe kitting cart is a customizable solution that can be tailored, quickly modified, or changed to meet the constant demands of continuous improvement processes in lean manufacturing. This allows manufacturers to quickly scale up or down the size of their carts to meet whatever changes they make to their production floor.
Given the importance of flexibility and scalability in lean manufacturing, a Flexpipe kitting cart is the perfect solution for continuous improvement environments.

Drawbacks of Welded, Fixed Kitting Carts
There are several drawbacks to purchasing welded, fixed kitting carts. First, asking for a customized welded kitting cart is extremely expensive. Welded kitting cart manufacturers prefer to stick to me-too, standard-sized welded carts. It allows them to mass-produce welded carts at lower costs. A customized welded cart would include non-recurring engineering design charges (NRE).
Second, the lead time for a customized welded kitting cart makes this option untenable. It can take weeks or even months before you receive your customized welded kitting cart. Third, welded kitting carts aren’t scalable or modular. They cannot be changed without incurring substantial costs for modifications.
Fourth, welded kitting carts don’t do a good job of protecting raw materials, parts, bins, tools, or consumables. These items are often haphazardly laid on the top of the welded cart. They’re allowed to move freely and damage is frequent. Finally, welded kitting carts are incredibly expensive, cumbersome, and difficult to maneuver.

Flexpipe Kitting Cart Design Principles
The first rule of designing any Flexpipe kitting cart is to ensure you’ve properly accounted for safety. Designing an ergonomic Flexpipe kitting cart with no protruding steel pipes, Flexpipe fasteners, or joints ensures that no production employees are accidentally injured.
Second, incorporating simple solutions like Flexpipe’s Kaizen foam ensures that all tools and critical items fit neatly and securely in their proper place. This is but another, simple Poke Yoke/failsafe solution.
Finally, you can easily add steel supports to your Flexpipe kitting cart to reinforce certain areas. Adding a simple 3-foot section of support pipe to a portion of your Flexpipe kitting cart to ensure its durability, typically costs no more than $10 when the Flexpipe joints are added.

Examples of Flexpipe Kitting Carts in Action


Before: Unstable wooden trolley where parts, tools, consumables, and different-sized raw materials were simply laid onto the wooden trolley. This was dangerous for employees as large sheets of raw materials and boards often hung on the side. These sheets often fell off while being transported as did other parts as nothing was securing them in place. Other issues were missing materials.
After: A customized Flexipe kitting cart with foam was constructed. This customized kitting cart had specific locations for different sheets of material and ensured that only the right-sized dimensions would fit. It properly secured the material in place, was much safer for operators and employees, and was easier to maneuver.



What to Include in Your Flexpipe Kitting Cart:
Given that a Flexpipe kitting cart is for providing critical components, materials, parts, and tools required for a given lean manufacturing workstation or workspace, ensuring your kitting cart includes locations for all these requirements is essential. Here are some tips on what to include in your Flexpipe kitting cart.
- Material Requirements: Define the material requirements that your kitting department will be including in the kitting cart. Define the amount of material required and its dimensions. Lean manufacturers often have a Bill of Materials (BOM). That’s the best place to start. You want to ensure that all the materials can be neatly contained and held in place within your Flexpipe kitting cart.
- Work Order Requirements: Manufacturers typically use work orders when releasing requirements to the production floor. These work orders provide a sequential breakdown of the work that must be completed to manufacture or assemble a finished good. Given that most manufacturing environments can be dirty, it’s a good idea to have a location on your kitting cart where the work order and assembly instructions are protected. They can be placed in plastic bags or removable containers.
- Tools: In manufacturing environments that have adopted 5S principles, workstations, and workspaces should always have a location for the tools they use throughout the day. However, if your work orders sometimes call out specific tools like Allen keys or small wrenches, then it’s best to ensure your kitting cart has a location for those.
- Flexpipe Kaizen Foam and Foam Inserts: Both are great solutions for protecting fragile material and subcomponent parts or for quick and immediate storage of smaller tools and consumables.

FAQ About Kitting Carts:
What is the loading capacity of a Flexpipe kitting cart?
There is no single universal capacity — it depends on the pipe lengths, wall thicknesses, and span configuration of your specific design. Flexpipe provides a free online loading capacity tool where you input each pipe span length and thickness, and the tool returns the maximum safe load for that section. Always run this calculation before finalizing your design. If a given level or span falls short of your target load, adding a mid-span support pipe and two joints typically costs under $10 and significantly increases capacity.
Can a Flexpipe kitting cart be built to support ESD requirements for electronics or aerospace assembly?
Yes. Flexpipe offers ESD-safe pipes, joints, decking surfaces, and casters that can be combined to build a fully compliant ESD kitting cart for use inside ESD Protected Areas (EPAs). This is critical for U.S. electronics manufacturers and aerospace suppliers where static discharge can destroy sensitive components or violate ANSI/ESD S20.20 requirements. An ESD kitting cart uses black ESD-coated pipes throughout the frame, conductive casters that maintain a grounded path to the floor, and static-dissipative shelf surfaces. Kaizen foam inserts are also available in ESD-safe versions to protect sensitive parts in their designated slots. See the full ESD product range at the Flexpipe ESD protection page.
How do Flexpipe kitting carts support sequenced parts delivery in U.S. automotive assembly plants?
In U.S. automotive plants running just-in-sequence (JIS) or just-in-time (JIT) production, kitting carts are built with compartments sized precisely to each part number in the kit. Because the compartment geometry only accepts the correct part, incorrect or missing components are immediately obvious before the cart leaves the kitting area — acting as a physical Poka-Yoke device. Carts are typically built to dock directly with tugger train systems, so a sequenced cart arrives at the line cell at the exact moment the operator needs it. For automotive-specific solutions and case studies, visit the Flexpipe automotive page.
What preventative maintenance does a Flexpipe kitting cart require?
Flexpipe kitting carts are built from cold-rolled SPCC steel pipes with a scratch-resistant polyethylene (PE) coating, making them highly durable in demanding manufacturing environments. Routine maintenance is straightforward: inspect all M6 joint fasteners periodically and re-torque any that show loosening, particularly on mobile carts that travel over floor seams. Check caster wheel condition and brake function at each shift if the cart is used heavily. Wipe down the frame and shelf surfaces as part of your standard 5S cleaning routine, and avoid overloading any level beyond its calculated capacity. A simple weekly visual inspection is sufficient for most U.S. production environments, with a more thorough check monthly.
How quickly can Flexpipe ship kitting cart components to a U.S. manufacturing facility?
Flexpipe ships standard pipe and joint components across the contiguous United States, with most in-stock orders fulfilled and dispatched within 1 to 3 business days. For facilities that want to minimize assembly time on the production floor, Flexpipe’s pre-cut pipe service delivers pipes already cut to your specified lengths — ready to connect with joints on arrival.
