Assembled Extension Spring for the Automotive Industry

Assembled Extension Spring for the Automotive Industry

At Sterling Spring, LLC, we manufacture 400,000 to 600,000 of this automotive release spring annually. This high volume project exemplifies our wide array of manufacturing, assembling and metal finishing capabilities.
The springs located on both ends are made out of .192" phos music wire, are coiled and looped on one of our shop's many CNC machines and are shot peened in-house to improve the cycle life. The connecting rod is manufactured out of .187" basic wire on custom tooling built for our Fourslide equipment.
We developed and fabricated a special punch press tool to fully automate the assembly and inspection of the final product. Our automation not only securely fastens the middle rod to the two springs and ensures a high quality product but also greatly improves our manufacturing efficiency to lower labor costs which is passed onto the customer to help their bottom line. The assembly is then run through our paint line and then carefully packaged to ensure parts arrive safely and ready for our customer's production line.
This spring is not a run-of-the-mill part that any spring company can manufacture. All of the manufacturing processes used are available in-house at Sterling Spring which allows us to control costs, reduce lead times, and provide our customers with diverse products for almost any spring application.
