Project Description

Restraint System Components

Application: Restraint System Torsion Springs

Problem: A torsion spring design with a specific pitch requirement was causing springs to become entwined during processing and shipping. Springs were being damaged in transit and the OEM was spending time and labor dollars to de-tangle parts before they could be used.

The MWI Solution:

  • Attempted to plate / ship in smaller lots
  • Worked with customer to understand end-use application requirements
  • Proposed a minor tooling change at the OEM
  • Developed a closed coil solution that solved the tangling problem


The customer was able to redeploy all workers involved in de-tangling and will save around $120,000 in production costs over the next 10 years. Capital Spring’s solution also allowed for larger lot shipments, removal of several process steps and damaged springs, and an improved speed-to-market for the OEM.
