Spiral Torsion Springs are the most commonly used type of flat spring and are sometimes used in place of the traditional torsion spring as they rotate in circular movements, the torque deliver per revolution is linear for the first 360 degree, at greater angular rotation, the coils begin to close on the arbor and the torque per turn increases rapidly also per revolution on nonlinear when closer to the axis, thus these type of springs are ideally suited for applications requiring less than 360° of angular rotation.

Our custom designed Spiral Torsion Springs are available in a variety styles, sizes and materials, this makes power springs useful in a wide variety of applications, with this complete selection of styles available, our experienced engineers can help you select a spring design to meet your needs.

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 Power Spring 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 Power Springs, please send us your application requirement, our experts will hand-select or commend the best solution for your specific needs.
