Product Description

Product Description

The coil torsion spring is designed to provide reliable rotational force and stable mechanical return in various industrial applications. Manufactured from high-quality spring steel or stainless steel, it offers excellent elasticity, fatigue resistance, and long service life.

These springs work by storing mechanical energy when twisted and releasing it as torque when returning to their original position. They are widely used in mechanical hinges, automotive components, electronic devices, clips, and hardware assemblies.

Custom sizes, leg shapes, and torque requirements are available to meet specific engineering designs. With precision forming technology and strict quality control, our torsion springs ensure consistent performance for both small-batch prototypes and large-scale production.
