What Are Compression Springs?
Compression springs are open-coil helical springs designed to compress under load and return to their original length when the force is removed. These springs are commonly used in valves, actuators, suspensions, and tooling.
Springtech supplies custom and standard compression springs, tailored to your material, size, and load requirements. All springs are manufactured in accordance with ISO and DIN standards.
