1. The basic performance of products processed by metal stamping must be satisfied. The assembly and repair of products need to be fast, convenient and easy.
2. The product of metal stamping is simple in shape and reasonable in structure. It can be beneficial to die processing. That is to say, it takes the least time and the simplest process to complete the whole part processing. It can quickly realize mechanized and automated production and improve production efficiency.
3. Hardware stamping parts should be processed with existing materials and equipment, process equipment and process flow as far as possible, and the life of stamping die should be guaranteed.
4. It can reasonably calculate the size of metal stamping parts under normal conditions, reduce the size accuracy level and surface roughness by about the size of specifications, and reduce scrap and loss.
