1、 Whitening of products processed by injection mold. The reasons for whitening of products processed by injection mold include:
1. Excessive load pressure.
2. Poor demoulding.
Treatment method: When designing the injection mold, pay attention to the enough demoulding slope. When making the injection mold, ensure that the cavity of the injection mold is kept smooth and clean, and immediately reduce the injection pressure for real-time processing.
2、 The reasons for the dents produced during the processing of injection molds are as follows:
1. Insufficient cooling of injection mold and insufficient cooling time will cause serious deformation.
2. This also happens when the internal pressure of the injection mold is insufficient.
3. The thickness of each part of the product is different.
Treatment method: reduce the barrel temperature and mold temperature, force cooling at the place where the dent occurs, fill the flow edge at the place where the dent occurs, and control the difference in the thickness of the designed product.
