The punching pin is one of the precision mold parts. The punching pin can enhance the strength of the thimble and prevent the thimble from deforming or breaking. Punching needle is one of the important connector mold parts in the mold. The quality of the punching needle has a great influence on the normal operation of the mold, so the processing requirements of the punching needle are also very high. When the punching needle is plastically deformed in the mold cavity, it flows and slides along the surface of the cavity, causing severe friction between the surface of the cavity and the punching needle, thereby leading
Cause the punching needle to fail due to wear. Therefore, the wear resistance of the material is one of the most basic and important properties of the punching needle. Hardness is the main factor affecting wear resistance. In general, the higher the hardness of the punching needle, the smaller the amount of wear and the better the wear resistance. In addition, wear resistance is also related to the type, quantity, shape, size and distribution of carbides in the material.
