The hardware stamping parts, before the customization, need to customize the stamping die first, and the stamping die needs the designers before processing, and then the design of the mold is carried out for the various requirements of the stamping part.

- The existing equipment, process equipment, and process flow shall be used to process it as far as possible, and the service life of the die is prolonged;
- To meet the product usage and technical performance, and facilitate assembly and repair;
- The utilization rate of the metal material is improved, the material variety and the specification are reduced, and the consumption of the material is reduced as much as possible. the material which is slightly lower in price is used in the case of being allowed, and the parts can be made to be free from waste and waste material blanking as much as possible;
- The method is simple in shape and reasonable in structure so that the structure of the die can be simplified, the number of processes is simplified, a simpler stamping process is used for finishing the whole part, the machining is reduced by other methods, and the punching operation is facilitated, so that the production of the mechanization and the automation is facilitated, and the labor productivity is improved;
- In the case that the guarantee can be used normally, As far as possible, the accuracy of the dimension and the roughness of the surface area required below, to facilitate the interchange of the products, reduce the waste, and ensure the stability of the product quality.
