High-performance Torsion Springs are engineered to exert rotational torque when twisted, providing essential energy storage and release for a wide array of mechanical systems. Crafted from premium spring steel wire, these components are available in diverse geometries—including straight, coiled, and spiral configurations—to ensure seamless integration into complex assemblies. With a focus on precision elastic coefficients and maximum torque capacity, our torsion springs deliver reliable stability for demanding industrial environments.
From automotive clutch and brake systems to precision electronics and industrial furniture hinges, our torsion springs are the backbone of rotational motion. Shijiazhuang TangChao Metal Products Co., Ltd. leverages over two decades of expertise and advanced machinery from Germany, Korea, and Taiwan to provide fully customized solutions. Whether you require specific V-shaped geometries or bidirectional types, our engineering team ensures every spring meets exact performance specifications for global clients across the USA, Europe, and Japan.

Frequently Asked Questions
Torsion springs store energy through rotational twisting (angular force), whereas extension springs store energy by being pulled apart (linear tension).
You need to capture five dimensions: Wire Diameter, Outer Diameter (OD), Inner Diameter (ID), Body Length, and the Length/Orientation of the legs.
We use premium spring steel with galvanized finishes to provide superior protection against rust and environmental degradation.
Yes, our experienced engineers can produce any shape or industry-specific spring according to your custom drawings and performance requirements.
They are widely used in automotive (clutches, brakes), electronics (switches, sensors), industrial machinery (valves), and furniture (hinges, doors).
Heat treatment enhances the elasticity and durability of the spring steel, preventing permanent deformation under load.
