Product Introduction




The Extension Spring is mainly used to control any mechanical action, such as the clutch spring, the brake shoe spring, the lateral support spring, the main support spring, the throttle spring, and the special moveable hook spring. In addition to the molding techniques of bending and winding, the tail cutting and de-stress annealing are key factors that affect the fatigue strength and lifespan of springs as far as the mechanical characteristics are concerned.

Specifications or drawing are welcomed and we will discuss further details with you.
