Unlike a compression spring, which is designed to keep two components apart, a tension spring is designed to apply force to bring two components together.
Tension springs have closely wound coils. They are manufactured this way so that minimal force is required to stretch them.
Based on customer requirements such as initial tension, consistent stiffness, and end attachment systems, we design the optimized spring (materials, coil diameter, number of coils).
Although we all tend to think of these springs in the context of trampolines, they are used across all industries—including automotive, aerospace, defense, and medical—in door mechanisms, braking systems, and more.
