Product Range
China Disc Springss are manufactured to EN 16983 (DIN 2093) specification and range in size from 8 mm to 800 mm outer diameter. China Disc Springs also offers a new type of technology called our Generation II Disc Springs. This new technology offers significant improvement in fatigue life while reducing diameter and assembly space. In addition to 51 CrV 4 (SAE 6150), China Disc Springs stocks a variety of antimagnetic, corrosion-resistant and heat-resistant materials for specialty designed applications.
Dependent upon spring thickness, blanks are manufactured by conventional stamping (Group 1), fine blanking (Group 2) or plasma arc/flame cutting (Group 3). High thickness springs are machined all over to remove surface imperfections. Depending on the requirement, disc springs can be heat-treated to achieve a martensite or bainite grain structure to extremely tight hardness tolerances. Shot-peening is performed on the parts to improve fatigue life. Phosphating and oiling is the standard corrosion protection and is done in house
