(1) The designed Automobile Press Parts must meet product use and technical performance and can be easily assembled and repaired.

　　(2) The design of Automobile Press Parts must be beneficial to improve the utilization of metal materials, reduce the variety and specifications of materials, and minimize the consumption of materials. Use low-cost materials wherever possible, and make parts as free as possible and with less waste.

　　(3) The Automobile Press Parts designed by Rongzhi Auto Parts must be simple in shape and reasonable in structure, so as to simplify the structure of the mold and simplify the number of processes, that is, to complete the processing of the entire part with the least and simplest stamping process, and reduce the use of other parts. The method is processed and facilitates the stamping operation, facilitating the organization of mechanization and automated production to improve labor productivity.

　　(4) Designed Automobile Press Parts, under the condition of ensuring normal use, Rongzhi auto parts stamping reminds as much as possible that the dimensional accuracy grade and surface roughness grade requirements are lower, and it is beneficial to product interchange, reduce waste and ensure product quality stable.
