Tungsten carbide punch is a part of the cemented carbide mold,which is mainly used for punching hardware parts or electronic parts,and other non-metallic parts can also be punched parts as well as belt holes, plastic holes, etc. Generally, we use carbide punches, die buttons and bushings together. Today, we will follow Oston Carbide to understand the classification and application of carbide punches.
The material is processed into parts by stamping die In the cold stamping process, Stamping is a pressure treatment method in which pressure is applied to materials through a mold installed on a press at room temperature to cause separation or plastic deformation to obtain the desired parts, which is relatively common in industrial production.
The precision of mold design and mold parts is directly related to the quality of stamping parts, production efficiency and production cost. In industrial production, according to the different needs of the product, the cemented carbide punches used in the stamping process have different shapes and carry out batch processing holes. 
At present, the common punch materials are high-speed steel punches and tungsten steel punches, etc., and high-speed steel is the most commonly used material, commonly used are CR12MOV, SKD11, SKD51, SKD61, etc. Compared with high-grade steel, Tungsten carbide punch is with higher hardness,high wear resistance and high corrosion resistance and other properties.
