15-year precision mould making

    Core pins is a kind of plastic mold parts, widely used in plastic mold. The use of the core pins:
    In the plastic mold, the core pins is the role of the separation of the products from the mold.
    Carbide core pins can be used for slender holes, such as tungsten steel core pins.
    The core pins may play the stable role in plastic mold.
    Type of plastic mold core pins: flat core pins, round core pins, standard core pins, non-standard core pins, etc.
    Thimble materials such as SKH51, SKD61, SKD11, 65Mn etc..
    SKH51 core pins the toughness is better than SKD61; the SKD61 core pins may bear 1600°C high temperature; SKD61 core pins the surface nitriding treatment can be very good to improve the core pins abrasion resistance; 65Mn thimble of poor quality, quality brittle and easy to break, most of the plastic mold has not used 65Mn core pins.
