1. The materials used for hardware stamping parts must not only meet the technical standards of the design product, but also meet the stamping process and processing requirements (such as cutting processing), electroplating, welding, etc.) before stamping.

2. In the shape of the stamping structure of the hardware, the hardware stamping parts should use a simple and reasonable structural surface (such as plane). With a small number of processing surfaces and processing areas, the spiral surface and combination should also be as many.

3. Select a reasonable preparation method in mechanical manufacturing. You can directly use profile, forging, stamping and welding. The choice of roughness is related to the specific production process conditions, which usually depends on the production batch, material property and processing probability of processing.

4. Metal stamping formability requirements. In the process of forming, the material should have good plasticity, so that the hardware processor is conducive to improving stamping forming and product quality. The curved strength of the material is less than the bending strength of the elastic mold. For the separation process, the material does not require good plasticity. The better the plasticity of the material, the more difficult it is.

5. Standard the proper manufacturing accuracy and processing costs of surface roughness parts. The processing cost of CNC stamping hardware will increase with the increase of accuracy, especially when the accuracy is high. Therefore, there should be no high accuracy without sufficient basis. Similarly, the surface roughness of metal stamping parts should be appropriately required according to the actual needs of the surface.
