Plastic mold processing as a processing technology, after its production or completion, there will be some defects. How to solve this situation?  
The reasons for the dents are:   
1) Insufficient cooling of the mold and insufficient cooling time will cause serious deformation.   
2) This situation can also occur if the internal pressure of the mold is insufficient.   
3) The thickness of each part of the product is different. In this case, the overall treatment method: reduce the temperature of the barrel and the mold, force cooling at the place where the dent is generated, fill/run the place where the dent is generated, and control the difference in the thickness of the designed product.
Causes of dents in plastic mold processing  
The reasons for product whitening are as follows.   
1) Excessive compliance pressure.
2) Poor demolding. In this case, the overall treatment method: When designing a plastic mold, pay attention to the degree of demolding to be sufficient. When making the mold, ensure that the mold cavity remains smooth and clean. The real-time processing should immediately reduce the injection pressure.
