( Power Springs )
Tech Spring is a professional Power Springs supplier, offering Power Springs and Pre-stressed Power Springs with standard design and high quality.
The steps of making Power Springs are winding the steel strip wound on arbor, and then confine them in a spring case. Power Springs can be widely applied to all kinds of retractor mechanisms. Pre-stressed Power Springs have more energy than power springs, at least up to 25%.
Constant Force Springs could offer high force output with very small space requirements and will provide a smooth, uniform load through its deflection. Deflection is limited only by the length of material in the spring. For general, Constant Force Springs can be used to LCDs, retractors, staple guns, fans, window curtains and other applications.
