coil spring

1.coil springs,no deformation of length,no damage of surface,long life-span.
2.coil springs 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 requirement.

coil springs have these ability:1.Export directly
2.Standard material
3.Responsive service
