15-year precision mould making

    With the development of precision mold parts processing industry, it is advisable to choose the high quality precision mold parts material, which can bring many benefits, such as effectively improve the service life of precision mold parts and   increase the production efficiency. Then, how to choose the high quality precision mold parts material?  It will be explained in further detail below.
    1. Meet the requirements of working conditions
    A. abrasive resistance
    When blank occurs plastic degeneration in precision mold parts cavity, it flows and slides along the cavity surface, making the cavity surface and billet produce severe friction. Its wear and tear lead to the failure of mold parts. So the abrasive resistance of materials is one of the most basic and important performance of mold parts.
    B. Toughness
    The working conditions of precision mold parts processing are very bad. Some often bear the large impact load, which can lead to brittle fracture. To prevent it suddenly brittle fracture at work, precision mold parts must have high strength and toughness.
    C. Fatigue fracture properties
    In the mold working process, under the long-term effects of cyclic stress, it often leads to fatigue fracture.
    2. Meet the requirements of technological properties
    A. Forgeability
    If having relatively low hot forging deformation resistance, the plastic of mold will be good, and its forging temperature range will be wide.
    B. Annealing process
    C. Machinability
    D. Grindability
    3.Meet the requirements of economical efficiency
    When choosing precision mold parts material, we must consider the principle of economical efficiency, to reduce the manufacturing cost as much as possible.
