618 Uses:

    Degree requirements for the mirror-polished plastic mold, plastic injection mold ordinary thermoplastic plastic injection mold and extrusion mold, blow mold. Forming mold compression braking mode (can be applied to public opinion, as required, or nitrogen flame hardening process.

618 advantages:

    Quenching crack and deformation without the risk of heat treatment, without heat treatment costs and shorten the molding cycle, reduce the cost of the mold (for example: no correction of deformation), easy to fix the mold can be subjected to nitriding and flame hardening to improve the mold side surface hardness and wear resistance
