At TSMC we manufacture custom torsion springs from round, square, rectangular and special section wire, the most common material types are stainless steel (type 302, type 316 and type 17-7 PH), music wire, spring steel and hard drawn steel. The spring legs can be at any position and have virtually any bent, hooked, twisted, looped or formed to conform to custom application. Spring ends are available in several standard forms, such as short hook ends, hinge ends, straight offset, straight torsion, special ends, straight torsion and double torsion.

Normally torsion springs are close wound but can sometime have pitch to reduce friction between the coils and are left hand or right hand wound, usually is designed to wind up, when the spring winds up, the coil diameter will decrease and the body length will increase. Direction of the wind is determined by whether the torsion spring is made to work in a clockwise or counter-clockwise rotation for a given application.

Our torsion springs are used in wide variety of industries including Automotive, Medical Equipment, Electrical equipment, Aerospace and Robotic systems, a common example of a torsion spring is that used in a clothes pins, clipboards, door hinges, retractable seating, digital cameras and numerous other uses.

As an experienced springs manufacturer, we can custom manufacture in a large choice of shapes of torsion springs to suit your design requirements.

Engineering Design

Custom products are a specialty of TSMC (Tech Spring Manufacturing Corp.), as a full service precision manufacturing company, our experienced engineers have extensive knowledge of custom parts, they are always available to assist you to conduct a comprehensive functional analysis of development and gives a feasible solution through our own formula from the preliminary design phase to fabrication that meets your application needs.

There are four critical factors when considering a Torsion Springs design such as Bore/ shaft (ID/OD), Load, Working height at which the load is applied and Material desired, as well as the other input parameters that contain the wire thickness, wire radial wall, active number of turns, work height, load at work height ... The input data as shown on the left table. And calculation results with spring rate (stiffness), working load (±10%), outer diameter at solid height, Working curve and Life cycles prediction where found in the down table.

Whether you need a standard or custom Torsion Springs, please send us your application requirement, our experts will hand-select or commend the best solution for your specific needs.
