Die steel selection
Mold steel selection is a very important part of mold manufacturing, so Huayang in the mold steel selection should first be based on the engineer's analysis of customer needs, product requirements, production capacity needs, service life and other conditions to determine, and then combined with the characteristics of different steel selection. P20 steel is generally used in hot pressing molds, 718H steel is generally used for product surface finish requirements, S136 or S136H steel is required for product surface mirror requirements, and NAK80 steel with excellent carving and discharge performance is used for injection molds with relatively complex mold structure.
