Custom OEM Manufacturing Wire Formed Torsion Spring

Product Description
Wire Formed Torsion Spring | Precision Industrial Part
The Wire Formed Torsion Spring is a precision-manufactured mechanical spring designed to provide controlled rotational force, return torque, and reliable positioning in a wide range of industrial and mechanical applications. Produced through precision wire forming and spring coiling processes, this spring can be customized to meet specific dimensional, torque, working angle, and installation requirements.
Unlike simple compression or extension springs, a torsion spring is designed to work primarily through rotational deflection. When the spring legs are rotated around the axis of the coil, the spring generates torque that can be used to return, close, position, or control a connected component. This makes wire formed torsion springs particularly useful in hinges, clamps, latches, actuators, switches, and mechanical control systems.
Our precision torsion springs are manufactured from high-quality spring wire materials, including stainless steel, spring steel, carbon steel, and music wire. Material selection can be optimized according to the required torque, fatigue life, corrosion resistance, operating temperature, and working environment.
Using advanced CNC wire forming equipment, the spring geometry can be accurately controlled during production. Wire diameter, coil diameter, number of coils, leg length, leg angle, winding direction, and overall dimensions can be manufactured according to customer drawings or samples.
The wire formed structure also allows complex spring geometries to be produced for applications where standard springs cannot meet specific installation requirements. Custom legs, hooks, offsets, bends, loops, and other formed sections can be incorporated into the design.
For OEM customers, we provide a complete custom wire formed torsion spring manufacturing service, from engineering review and material selection to prototype development, testing, mass production, and quality inspection. Our goal is to provide reliable spring components with consistent dimensions and repeatable mechanical performance.
