Tungsten Carbide Punch Applications Due to the high punch size requirements, withstand greater impact loads and higher frequency of production, punch commonly is made by a high-speed steel or tungsten carbide material, tungsten carbide has high hardness, high hardness, high wear resistance, high red hardness, etc., generally used in demanding punching mold. Tungsten carbide punch are combined with the punch bar, punch nut, punch mother used together, generally used for punching tower plant uses. When stamping, large punch holes simultaneously processed hundreds takes less than one second, so greatly improves production efficiency. Therefore, tungsten carbide punch widely used in machinery manufacturing, automobile manufacturing, aerospace manufacturing and other fields.
