Power Springs, also known as clock springs. Power Spring and Pre-stressed Power Springs are formed by winding a strip of material on an arbor and into a case or retaining ring to create a compact power source. When a pre-stressed power spring is released, it assumes S shape, while power spring a spiral shape. The advantages of pre-stressed power spring are as follow: 1. Pre-stressed power springs are pre-stressed to produce a flatter torque gradient than conventional power springs. 2. Pre-stressed power spring can store 25% ~ 55% greater energy than power springs. 3. Pre-stressed power spring also has higher turns than power spring when their sizes are the same. Ming Tai has innovated and developed power spring to for pen-type drug injector application. Powered by Ming Tai's innovative spring technology, precision pen-type drug injectors feature a strong performance, force profile of power spring can precisely match typical syringe glide force profile. Power springs are mainly used in clock, spring motors for toys, timers, as well as in retractor mechanisms for electrical cords, compressor pipes and seat belts. Lots of automotive parts have a power spring embedded into the mechanism to improve safety and convenience. Seat belts are one example of a critical auto part that has a constant force spring embedded into its mechanism. The device allows for flexible retrieval and automatic retraction of a seat belt to conveniently keep passengers both secure and comfortable.
