Dong Mu spiral spring, no deformation of length, no damage of surface, long life-span.
1.Dong Mu spiral spring, no deformation of length, no damage of surface, long life-span.
2.Spring material: selection of high-quality material production, fatigue resistance, temperature resistance, good toughness.
3.pressure deal: Spring with intensity of pressure more than three times to eliminate the use of prestress and deformation of spring will not happen again, to reduce phenomenon of fracture.
4.Shot penning deal: spring after shot penning to deal with strengthening the surface, the surface of the solid organizations, to increase the intensity of stress concentration, and to extend spring fatigue life.
5.Frequency of use of spring: the highest frequency of up to a thousand times / min, dies of modern design, must have high-quality die spring, Dong Mu spring can meet your requirements.
