During the heating runner pouring system, the pouring system is partially or completely heated during injection

when heating the runner pouring system, the pouring system is partially or completely heated during the injection process, so that some or all of the plastic in the mold pouring system, during the production period, the molten state is always maintained, so that only the plastic parts need to be taken out when the mold is opened, and there is no need to take out the flow channel condensate, or only a small part of the flow channel condensate. After the heating runner mold is shut down, the heating method is used before the next start-up to melt the runner condensate and start production. It is equivalent to extending the nozzle of the injection molding machine to the mold or even to the cavity.

The Hot runner injection mold we are talking about at present mainly refers to the hot runner injection mold, which is also the focus of this chapter. For the convenience of narrative, the following is the hot runner injection mold referred to as the hot runner injection mold.

Hot runner pouring system is mainly composed of heat injection nozzle, heat flow channel plate, heat insulation element and temperature control electric box. The heating element mainly includes electric heating ring, electric heating rod and heat pipe.
