1, the design of stamping parts and products must meet the technical performance, and can facilitate the assembly and repair.

2, the design of stamping parts must be conducive to improve the utilization of metal materials, reduce the variety and specifications of materials, as much as possible to reduce the consumption of materials. In the case of allowing the use of inexpensive materials, as far as possible so that parts do not have to waste and scrap scrap cutting.

3, the design of stamping parts must be simple shape, reasonable structure, to help simplify the mould structure, simplifying the number of processes, i.e., the one with the fewest, the simplest of stamping process to complete the parts processing, reduce the use of other processing methods, and is conducive to stamping operation, for the organization of the realization of mechanization and automation of production, to improve labor productivity.

4, the design of stamping parts, in guarantee under normal use, try to make the accuracy class size and surface rough degree requiring a low number, and to swap, reduce waste, ensure product quality is stable.
