The manufacturing of the springs discs is being done with regard to high quality standards such as “photo sensoring” for eliminating misblanking. The punching capacity is from thickness 0.1 mm (0,0039”) to 6 mm (0.23”). Also the heat treatment is done under controlled atmosphere and process parameters. The resultant product is distortion free with uniform hardness.
All heat treated disc springs are flattened on an automatichydraulic press at 1.5 times the load at 0.75h. Each spring is tested with the load cell for load versus deflection characteristics as per DIN 2093. Depending upon the application, the customised disc springs are also tested for its progressive and regressive load charecteristic, thus ensuring the complete process validation as per specification. |
