Matters needing attention in mold processing:

One, wear resistance: can not make the mold due to wear and failure, easy to pull the cover punch processing, so wear resistance is the need for a lot of work.

Ii. Strength and toughness: Most of the working conditions of molds are in bad condition, so it is easy to cause brittle fracture in the processing plant of easy pull cap punch under large impact load.

So to prevent this from happening, the requirements for strength and resilience are very strict.

Iii. Fracture and fatigue performance: During the working process of the die, under the long-term action of cyclic stress, the die often leads to fatigue fracture.

Four, high temperature performance: in the mold at a high temperature, will cause the decline in hardness and strength, and then plastic deformation and wear caused by the failure.

So in the high temperature performance is also relatively high requirements.
