What are the reasons for insufficient and uneven hardness of plastic mold processing?

The hardness of die heat treatment is a very important mechanical property index, and the unqualified hardness is a very serious defect. After heat treatment, insufficient or uneven hardness will reduce the wear resistance and fatigue strength of the mold. Plastic mold processing manufacturers say that this will lead to early failure of the mold and seriously reduce the service life of the mold.

Design requirements for injection molds

The characteristics of the injection mold are determined by the characteristics of the raw materials. There are two main points: one is the filling flow characteristics of the plastic melt during injection, and the other is the shrinkage position of the plastic in the cavity during cooling and solidification.

Injection mold processing process analysis

Injection moulds are almost batch forming in the process of injection processing. At this time, the processing method and process of injection moulds are particularly important. If they are not processed according to the requirements of the rules, it is likely to damage the injection moulds. To this end, Changzhou Ming chuang plastic industry provides injection mold processing method process analysis: generally, do not need to dry materials.
