Basic conditions for mold embryo work

Mold mold embryo plays an important role in mold manufacturing. Hardness is one of the necessary conditions for mold mold embryos. Hardness is the main factor affecting wear resistance. Generally speaking, the higher the hardness of the molding part, the smaller the wear, the better the wear resistance.
When plastic degeneration in the mold cavity, it flows along the surface of the mold cavity and slides, causing severe friction between the surface of the mold cavity and the ingredients, causing the mold to fail due to wear. Therefore, the abrasion resistance of the material is one of the basic and important performance of mold mold embryos. In addition, wear resistance is also related to the type, quantity, shape, size, and distribution of carbides in the material.

During the work of the mold, the mold will be repeatedly heated and cooling, causing the surface of the mold cavity to be stress stress, causing the surface to crack and peel off, increase friction, hinder plastic deformation, reduce the size and accuracy, which will cause the mold to fail the mold. Cold and cold fatigue is one of the main forms of heat -making mold embryo. Therefore, mold mold embryos and some molds should have high hot and cold fatigue resistance.
