Parts Kitting

Streamline Your Work

We develop and logically package parts kits that streamline your final assembly process, increasing quality while reducing overall costs of the finished product. Our process organizes parts so they can be delivered to the assembly floor when needed. Each year, we produce over 2,000 vehicle kits and ship over 500,000 SKUs.

With our kits, there’s no need for assemblers to search for inventory, pull parts, and record usage and supply levels. They can focus on the task at hand, improving productivity and reducing material handling time. We also fulfill general sales orders from our inventory.

Cost-Effective Process

  • Free up space, eliminate clutter
  • Reduce labor costs and downtime
  • Reduce inventory
  • Improve cash flow

Lean Racks

Boost Savings and Safety

Lean racks, carts, and storage systems economize on space and provide a more efficient way to deliver parts to an assembler. We design, prototype and produce heavy-duty, custom-built racks and other structures to reduce assembler movement as work is underway. Productivity on your work floor rises when the parts-delivery racks are designed to facilitate economized movement off the rack and into the workflow.

As we design and produce your adjustable racks and carts, you’ll see savings from a more ergonomically beneficial assembly process that reduces employee fatigue with an investment that lasts for years.

Strong, Tangible Results

  • Improve material flow
  • Eliminate unneeded steps
  • Improve ergonomics
  • Reduce worker fatigue
