Product Introduction:

Plastic die steel is a kind of die steel used for plastic manufacture. Plastic mold materials are mainly die steel. The
development of die steel has promoted the development of industrial products to the direction of high grade,diversification,individualization and high added value. All countries in the world have counted the output of die steel into alloy tool steel,which accounts for about 70% ~ 80% of alloy tool steel.

 

Plastic die steel can be generally divided into six categories: aging hardening plastic die steel (including mirror die steel),corrosion resistant plastic die steel, carburizing plastic die steel, pre-hardening buried material die steel (including free cutting steel), tempering plastic die steel and quenching plastic die steel. The more widely used are aging hardening plastic die steels, carburizing plastic die steels and prehardening plastic die steels
