The
punch mold parts manufacturer should take into account the productive capacity of the workpiece when choosing the punch die material. There is no need to choose the high life of the mold material if there is less production. Also should consider the material of the workpiece. Different material of the workpiece using the punch die material is different. For punch die, wear resistance is an important factor to determine the life of the mold. The wear resistance of the steel depends on the state of the carbide and the hardness of the matrix. The higher the hardness, the more the number of carbides, the better the wear resistance. The good or bad order of the wear resistance of the steel used in the
stamping mold components is carbon tool steel - alloy tool steel - matrix steel - high carbon high chromium steel - high speed steel - steel bond hard alloy - hard alloy.
In addition, we must consider the impact of these factors on the choice of stamping mold material that workpiece thickness, shape, size, accuracy requirements, etc..
