Why do plastic molds produce dents?

by:Vowin Rapid Prototyping     2023-02-22
As a production process of plastic materials, plastic mold processing will have some unfavorable conditions during the manufacturing process. So how to solve this situation?

What are the causes of dents in plastic mold processing?
1) Insufficient cooling of the plastic mold, insufficient cooling time will cause serious deformation.

2) This situation will also occur if the internal pressure of the plastic 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 cylinder and the mold, force cooling at the dent, fill the edge at the dent, and control the difference in the thickness of the designed product.
