In mechanical and electrical products, there are three main types of springs with large consumption:
1) Motor vehicle springs mainly for automobiles;
2) Electronic products spring based on household appliances;
3) Optical device springs mainly for cameras, copiers and cameras.
Motor vehicle springs are mainly developed in the direction of high strength to reduce the mass; The spring of electronic products is mainly developing in the direction of miniaturization; The spring of the optical device is mainly developing in the direction of both high strength and small shape. The corresponding spring design methods, materials and processing technology have been developed.
