Plastic mold casting system can be divided into three categories according to different system types.

(1) Door mold, gate and gate parting line, mold and stripping, the simplest design, easy processing, low cost, so more and more people use the door system operation.

(2) Nozzle mold: the gate and gate line are not classified, usually a set of nozzle parting line is designed directly in the product design, the design is more complex, the processing is difficult, often according to the product requirements to select fine nozzle system.

(3) Hot runner mold, mold is the same structure and fine nozzle, the biggest difference is that one or more heat flow, temperature and hot suction nozzle, but not cold feeding demoulding, runner and gate directly on the product, so the port does not need demoulding, also known as pouring system, the system can save raw materials, suitable for raw materials more expensive, high demand Product and mold design and processing are difficult and cost is high. Heat flow passage system is also called heat flow passage system. It is mainly composed of heat flow passage cover, heat flow passage board and temperature control electric box. There are two common heat flow channel systems: single point heat flow channel and multi-point heat flow passage. A single point hot runner is used to directly melt molten plastics into the cavity with a single heat gate sleeve. The multi-point hot gate is used to branch the molten material into each hot gate sleeve and then enter the mold cavity through the hot gate plate.
