15-year precision mould making

    Friends, who are in the mold parts industry, will want to know how to improve the service life of die casting core. Today, I will share it with you about it.
    First of all, control the material. You should choose the high quality steel. When treating with the heat, the hardness should control  within 46 HRC. Don't be too hard. The more hard, the more likely it is to bad.
    Second, the design of casting die core. The front has no sharp corner, reverse R0.25. The roots has no sharp corner, too. C Angle allow to transit by R within the size. It can facilitate the after-processing or assembling with C Angle or R.
    Third, the design of passageway to avoid the core, in order to avoid the high temperature shock. It can add cooling process if exceed the diameter over 16mm.
    Then, Control the process of die casting process. The temperature of aluminum liquid should remain stable to avoid dramatic change. The spraying mold release agent gives priority to oiliness. When replacing a fracture core, you should check whether there is a slight crack phenomenon in other accessories. The suggestion is to replace all.
    Last, Record the service life of casting die core. Under the condition of the permit, you'd better to replace all within a period of time.
    If you want to improve the service life of core, you should obey the above five considerations. And if you need long life of precision mold components, you can come to Yize Mould to order. The price is favorable, and the quality is very good. You can rest assured to buy!
