Tension Springs

About tension springs

This tension spring is used for tensile load. Body part is close wound. The inner strength which is called initial tension at close wound part while having no load is considered, then designed and manufactured. Basic hook shapes of extension spring are on the picture.

Micro/tiny/small tension springs are also available!

Manufacturing technology

We use three ways to manufacture springs based on the production type.
Mass-production springs are manufactured by coiling machine and small-production springs are done by core bar winding and hand winding.
