Buy China foldable crates molds Factory:The choice of mold material needs to meet three principles. Mold to meet the wear resistance, strength and toughness of the work requirements. The mold meets the process requirements.At the same time, the mold should meet the economic applicability.

1. Wear resistance
When the billet is plastic deformation in the mold cavity, it flows and slides along the surface of the cavity, resulting in serious friction between the surface of the cavity and the billet, resulting in mold wear failure.
Therefore, the wear resistance of the material is one of the most basic and important properties of the mold. Hardness is the main factor affecting wear resistance. Generally speaking, the higher the hardness of the mold parts, the smaller the wear, the better the wear resistance.
In addition, wear resistance is also related to the type, quantity, morphology, size and distribution of carbides in the material.
2.Toughness
Most of the mold working conditions are very poor, some molds often bear a large impact load, prone to brittle fracture.
