Causes of dents in plastic mold processing

Core tip: as a processing technology, plastic mold processing will have some bad conditions after its production or completion. How to solve this situation? Let’s talk about two of the more common ones.

1. Dent. The causes of dents are:

1) Insufficient cooling of the die and insufficient cooling time will cause serious deformation.

2) This situation also occurs when the internal pressure of the die is insufficient.

3) The thickness of each part of the product is different. In this case, the overall treatment method is to reduce the barrel temperature and die 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.

2. Product whitening. The causes of product whitening are as follows.

1) Excessive load pressure.

2) Poor demoulding. In this case, the overall treatment method: when designing the plastic mold, pay attention to the sufficient slope of demoulding. When making the mold, ensure that the mold cavity remains clean and clean, and reduce the injection pressure immediately in real-time treatment.

There are many kinds of bad phenomena in the process of plastic mold processing. I hope you will be careful in the process of operation and strive to make the most perfect works.
