    Technology
     
    1) Mould structure design
    Professional designers provide you with reasonably designed mould to shorten cycle hours.
    Reducing unnecessary procedure improves efficiency.
     
    2) Mould cooling system
    According to the structural characteristics of the product and the appearance of the product , We design a reasonable form of gate for mould, such as a large gate, hidden gate, fan gate, needle gate, pin point gate etc., a reasonable channel of runner design make mold temperature balance in the shortest time to improve mould precision and productivity.
     
    3) Accessory for mould
    Slide, guide pin, guide sleeve, lifter blocks and so on are taken by wear-resistant standard parts, to ensure the mould life.
     
    4) Deal with mould
     Quenching the mold, heat treatment to improve the hardness, then Nitriding temperature is lower , the mold will no longer need to quench mold with high surface hardness and wear resistance more than HV850
     
    Service
     
    1) We can repair the mould in one year for some free and provide technology.
