What should I do if the mold sticks in the main channel during the injection molding process of the milk warmer?

What should I do if the mold sticks in the main channel during the injection molding process of the milk warmer? Main channel sticking refers to a phenomenon that plastic products stay in the main channel and cannot be successfully separated from the mold during the injection molding process. During the injection molding process of the milk warmer, what is the reason for the mold sticking, and how to solve it? Shanghai Mulan Injection Molding Factory focuses on the customized business of small household appliances, household beauty instruments, and maternal and child products. accumulated a wealth of experience. Aiming at the reasons for mold sticking in the main channel, the following suggestions are given:

1. Insufficient solidification of the main channel

What should I do if the mold sticks in the main channel during the injection molding process of the milk warmer? When the milk warmer accessories are injection molded, the main channel melt has not yet fully solidified, the shrinkage is small, and the strength is also low. At this time, if the main channel exits, it will be very easy to break, causing the main channel to solidify and fail to form. The melting material temperature, mold temperature and cooling time will more or less affect the product on the solidification of the sprue. At this time, by reducing the mold temperature and prolonging the cooling time, the main channel can be fully cooled and solidified before demoulding;

2. Excessive pressure applied

The sprue is generally closer to the nozzle of the barrel. After a high pressure is applied, the size of the sprue will increase, resulting in an increase in the resistance during demoulding. It is inevitable that the sprue will stick to the mold. At this time, the holding pressure needs to be reduced, but excessive reduction will lead to unstable injection volume, so the holding pressure needs to be controlled at a reasonable value.
