Hot runner system

Hot runner is an advanced injection molding technology in plastic injection molding process. Compared with traditional cold runner injection molding, hot runner injection molding can precisely control the heat in the mold during the injection molding process, so that the plastic material can flow to the complex parts of the mold faster.

The advantages of hot runner injection molding include:

Reduced material waste: Compared with cold runner injection molding, the plastic material used in hot runner injection molding is more precise, so it can greatly reduce waste.

Improve production efficiency: Through better control of heat in hot runner injection molding, the plastic material is more evenly spread on the surface of the mold and quickly reaches the far corners of the mold, which can greatly improve production efficiency and reduce production time.

Improve the quality of injection molded parts: hot runner injection molding can better control the flow of plastic materials, thereby reducing the appearance of defects, such as submerged spears, etc., and can produce more consistent injection molded parts
