Mold Spring-Green（TH）

Description

We have various specifications of yellow springs, blue springs, red springs, green springs, brown springs, and some heat resistant springs, extension springs.
We use the best spring steel wire, good fatigue resistance, strong elasticity.
Our spring has accurate inside and outside diameter and small length error, which is suitable for the use of precision mould.

Green spring is a heavy load spring, suitable for stamping die
