use
718 mold steel uses the same as P20 type mold steel, but because of better hardenability and better performance, it can make large-sized, high-grade plastic mold forming parts. With the development of plastic molds, there will be more and better updated improved mold steel numbers, such as B30H of Baosteel in China.
Thermoplastic injection mold, extrusion mold.

Mold steel

Vacuum degassing refining process is pure steel, suitable for plastic molds requiring polishing or etch processing.
It is supplied in the pre-hardened state and can be directly used for mold processing without heat treatment, which shortens the construction period.
After forging and rolling, the structure is dense, 100% ultrasonic inspection, no pores, pinhole defects.
