Power Spring is essentially manufactured from a long length of steel strip which is tightly wound and constrained within a space. This constraint is designed in such a way as to allow the spring to wind up further to increase the energy stored but to also constrain the spring to preload wound condition. Allowing the spring to unwind back to it's constrained diameter to use the available energy to actuate a mechanism.
