1. The temperature of the molten plastic is too high, which will increase the cooling time of the product.Injection Industry， At this time, the temperature of the barrel should be reduced, the screw speed or back pressure should be reduced, and the temperature of each section of the barrel should be adjusted.

2. The temperature of the injection mold is high, which affects the cooling and shaping of the molten plastic, which will cause the injection molding product to be closed and closed and shut down. To improve this situation, targeted cooling of the water channels is required.

3. Insufficient heating of the injection molding machine barrel. In this case, a machine with a large plasticizing capacity should be used or the preheating of the material should be strengthened.

4. The injection molding machine nozzle drools. In this case, the temperature of the barrel and nozzle should be controlled or the self-locking nozzle should be replaced.
