Compression Springs Speciality:
We develop the solution matching your application. When designing a compression spring or a compression spring package, we define the technically required material exhausting the economic limits. In this case, we always aim at a maximum service life. Our range of services covers the performance of long-term tests with up to 10 million load changes on a test equipment developed by ourselves.
