　　The surface treatment of electronic stamping parts plays the following roles:

　　Electronic stamping parts can have a good decorative effect after electroplating. Many of them are decorated with different materials under the premise of taking into account the performance of the surface protection system. The Cu layer and Ni layer play a protective and educational role, while the surface-plated Cr layer can maintain the decorative metallic luster for a long time.

　　The role of functionality, electroplating of different materials and the surface resistance to high temperature or low temperature, electrical conductivity or insulation, magnetic or magnetic shielding, light enhancement or reflection, lubrication, biocompatibility or biological exclusivity and other new functions, play a new role.

　　Repairability: The surface of electronic stamping parts is damaged due to corrosion, abrasion or other factors. The surface dimensional accuracy of the workpiece can be restored through single or composite surface treatment technology, and can be redesigned to give it equal to or even exceed the surface performance and social function of the new product, so as to improve the remanufacturing of the workpiece, assembly or product.

　　In addition to the above functions, the surface treatment of electronic stampings has other functions, such as the use of electrodeposition technology in surface engineering technology, magnetron sputtering technology can be used to prepare nanoparticles, nanofilms, and thermal spray technology to prepare nanostructures Material etc...

　　Molds are various molds and tools used in industrial production to obtain the required products by injection molding, blow molding, extrusion, die-casting or forging molding, smelting, and stamping. In short, molds are tools used to shape objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the molded material, and is known as the "mother of industry".

　　There is an essential difference between the process characteristics of fine blanking and ordinary blanking. Normal blanking controls the tearing of the sheet during the blanking process, while fine blanking tries its best to suppress the tearing of the sheet during the blanking. The fine blanking is always kept as one body before the parts are separated from the sheet material, and the metal sheet is always in the plastic deformation process during the fine blanking process.

　　In order to achieve this purpose, the V-shaped blank holder and the counter-pressure plate first press the sheet before punching to prevent the movement of the inner and outer metal sheets during the punching process. In addition, with the small gap between the convex and concave dies and the appropriate small rounded corners of the concave die, the three-way compressive stress state of the local area of the punching is formed during the punching process, so as to ensure the plastic deformation process of the punching. In addition, the fine blanking material and lubrication state also have a great influence on the fine blanking effect. The material with fine spherical carbide structure with good plasticity, low deformation resistance, complete spheroidization, good dispersion and uniform distribution is suitable for fine blanking. Good lubricants not only improve the quality of fine-blanking parts, but also help reduce the wear of the mold and increase the service life of the mold.
