The phenomenon of material leakage in hot runner

In the advantages and disadvantages of hot runner, I mentioned that the hot runner system will produce leakage, and this problem has not been solved. The leakage phenomenon of the hot runner system has now become a common concern for mold makers, who believe that the molten material in the hot runner system will leak into the分流plate槽. This has almost become the main reason for the mold to be deactivated and damaged. We all know that the reasons for leakage are varied. In most cases, the leakage of the hot runner system is not due to design problems, but is caused by improper operation.
