First point: wear resistance
When the billet is plastic denatured in the mold cavity, it moves and slides along the outer surface of the mold cavity, which causes severe conflict between the outer surface of the mold cavity and the blank, and then leads to the failure of the mold due to wear and tear. So the wear resistance of materials is one of the most basic and important functions of the mold.
Hardness is the primary factor affecting wear resistance. Generally speaking, the […]
