Custom Designed Compression Springs

Leveraging our 100-plus years of experience, the spring specialists at Hardware Products Company are capable of forming any type of spring imaginable, from miniature to gargantuan, including complex configurations.

A compression spring accepts a load and “compresses” as the load is applied. It returns to its free length when the load is removed. Compression springs are most commonly used in a vast variety of machinery from simple mowers to advanced spacecraft. All designs are verified by Spring Manufacturing Institute (SMI) software.

 

Custom-Designed

You have access to all our expertise at forming springs of any dimension and complexity, ultimately giving you control of your custom-design compression spring needs. We will assist you in the design of the compression springs to meet your unique specification. It’s as simple as sending us your application. From there, we enter your parameters into our official SMI spring design program, and follow-up with you, providing our precision recommendation. You are in control of final adjustments and approvals.
