Application: Military Infrared Imaging Systems
Problem: The application requires highly precise compression springs and the previous spring supplier was unable to manufacture a conforming part. Cryogenic units were failing in performance tests. Customer was forced to disassemble, test and sort for the springs that met tolerance (around 50%), and reassemble, which was drastically increasing their labor expense and causing shipping delays in the final product.
The MWI Solution:
- Developed proprietary coiling and grinding process to achieve required tolerances
- Designed in-house testing equipment to certify spring force, eliminating customer testing requirement
- Worked with material manufacturer to solve secondary high-temperature issue observed in testing
After a few months of R&D, MW Industries was able to consistently manufacture 99.5% of springs to meet the required tolerances. The customer was able to replace their spring supply, as well as increase production throughput and overall capacity to gain more market share.
