Power springs store and release rotational energy in form of torque via the center arbor or spring housing.
There are 2 kinds of power springs in YongSheng, they are conventional power springs and pre-stressed power springs and all made of 301 stainless steel.
when the stainless steel strip is shaped through the spring forming machine, it will generate torsion. Pre-stressed power springs will entail the added recoil process than conventional power springs before packaging.
High-torque delivery per unit of deflection.
Normal residual stresses.
Pre-stressed power springs can store 25% ~ 55% greater energy than conventional.
