The technical requirements of metal bending parts should be developed in the direction of messy structure, increased block size, more parts on related edges, larger bearing capacity and severe internal stress restrictions, which can promote the development of special stamping forming technologies. For example: hydraulic forming, fine forming, explosive forming, spinning forming, die-free forming, laser forming and electromagnetic forming technologies.

Metal bending parts planning indicators:

1. To meet the requirements of product usage and technical functions, and to facilitate assembly and repair.

2. It is conducive to improving the utilization rate of metal materials for metal bending parts, reducing the types and standards of materials, reducing the consumption of materials as much as possible, and using inexpensive materials where possible to make parts as waste-free and scrap-free as possible.

4. Hardware bending parts should be designed to be machined using existing equipment, process equipment, and processes as much as possible, and to extend the service life of the die.
