Compression springs are used to offer resistance to applied compression forces and are the most common spring configuration. While the most widely manufactured is a straight cylindrical spring we can also coil conical, barrel or hourglass shapes with variable or consistent pitches. Depending on the application and design, a compression spring may need additional operations to assure optimum performance.
We are often faced with space constraints when designing a spring for our customer so we are forced to push the stress limits of a spring. This usually results in a spring with ground ends and a press operation to remove the set and lower stress levels. Cook Spring maintains a first class grind and set removal department with proprietary equipment that complements our hi-tech machines. This allows us to offer quality solutions for both high and low volume applications.
