Torsion Spring Principles and Design Guide: Single vs. Double Torsion Springs

Mar 17, 2026

A torsion spring is an elastic mechanical component that stores mechanical energy. When the spring is twisted by an external force, it generates a restoring torque in the opposite direction, proportional to the angle of deflection. Chiao Ta Spring specializes in the design and manufacturing of precision torsion springs with wire diameters ranging from 0.1 mm to 3 mm. We offer single torsion springs, double torsion springs, custom leg angles, and various surface treatments to meet different application requirements. Our torsion springs are widely used in medical devices, electronic equipment, and automotive components, and we support product testing and customized development to help customers achieve optimal performance for their applications.
