15-year precision mould making

    Improve the service life of the custom mold parts should pay attention to these aspects:
    1, The use of advanced and reasonable forging process, so that the carbide distribution is uniform, the formation of a reasonable metal flow line, improve the wear resistance, isotropic and anti adhesive ability.
    2, Strictly control the machining quality, the influence of the grinding process of die working parts on the service life of the mold is the biggest. When grinding, the surface of the workpiece will appear the grinding stress, the grinding crack and the grinding heat, which will reduce the fatigue resistance and corrosion resistance of the die parts.
    3, The reasonable heat treatment process was used to ensure the mold parts with high thermal strength and tempering stability, in order to obtain high thermal fatigue resistance and wear resistance.
    4, The surface strengthening process can prevent hot crack expansion, improve the mold parts surface strength, wear resistance and corrosion resistance.
5, The mold assembly should be strictly in accordance with the assembly process to perform, to meet the requirements of mould drawing.
