Common Faults Of Injection Mold - DGMF Mold Clamps Co., Ltd

Injection mold is a tool for producing plastic products; it is also a tool for giving plastic products a complete structure and precise dimensions. The structure of the injection mold and the quality of mold processing directly affects the quality and production efficiency of plastic parts. The most common and most common causes of injection mold failures and troubleshooting methods in the production of injection molds and plastic products are described in detail as follows:


1. Difficulties in gate stripping


During the injection molding process, the gate stacks to the sprue sleeve and is not easy to come out. When the mold is opened, the product is cracked and damaged. In addition, the operator must knock out the tip of the copper rod from the nozzle to loosen it before demoulding, which seriously affects production efficiency. 


The main reason for this failure is the poor finish of the gate taper hole, and there are knife marks in the circumferential direction of the inner hole. The second is that the material is too soft, the small end of the taper hole is deformed or damaged after a period of use, and the curvature of the nozzle spherical surface is too small, resulting in the riveting head of the gate material.
