PROSTAK™ Case Study: J.W. Speaker Corporation

J.W. Speaker Corporation is a global leader in the research, design, prototyping, and manufacturing of advanced vehicular lighting solutions for original equipment manufacturers (OEMs). As part of expanding operations, the company began construction of a new production facility in Germantown, Wisconsin—bringing new challenges in tooling storage and space utilization.

The Challenge

J.W. Speaker needed a safer, more efficient way to organize and store a large number of injection molds, some weighing up to 8,000 pounds. With limited floor space available in the new facility, they required a system that could maximize vertical storage while maintaining safe handling and accessibility.

The Solution

Rapistak implemented a fully customized PROSTAK™ Stacker Storage Management System, engineered specifically for J.W. Speaker’s operational needs.

Key features of the system included:

  • A double-aisle rack configuration standing 20 feet high
  • 36" x 36" steel pallets, adjustable in 4-inch vertical increments
  • Storage flexibility to accommodate molds weighing 4,000, 6,000, and up to 8,000 pounds
  • Strategic use of overhead space while keeping the heaviest molds accessible at floor level

This design allowed J.W. Speaker to store over 400 injection molds within a footprint of just 28'-0" x 54'-0" (1,548 square feet).

The Results

The PROSTAK™ system delivered significant operational improvements:

  • 33% space savings compared to conventional pallet rack systems
  • Improved safety through better handling and storage of heavy molds
  • Increased productivity with more efficient access to tooling
  • Enhanced inventory control and organization
  • Maximized use of vertical space, freeing up valuable floor area for production equipment

Conclusion
By adopting Rapistak’s PROSTAK™ Stacker Storage Management System, J.W. Speaker successfully optimized its new facility layout—achieving safer operations, better organization, and greater storage efficiency without sacrificing valuable production space.
