What’s the Requirement of Plastic Mold?

Plastic mold working conditions is different from cold die. It generally works under the condition of 150 ° C to 200 ° C. except it received pressure from outside and needs to bear the influence from the temperature.

According to the molding condition of plastic mold and different ways of processing, we can know the basic performance requirements of plastic mold.

It needs hard enough surfaces to make sure the mold has enough stiffness. As mold needs to have larger compressive stress and friction in the work, it requires keeping the precision of the original shape and the stability of accurate size in order to keep the length of using. The wear resistance of mold depends on chemical components of steel and heat treatment hardness, so increasing the mold hardness is good for improving its wearability.
