An injection mold hot runner system is a system that uses a heating system to keep the molten plastic at a constant temperature throughout the processing of injection from the injection molding machine to the mold cavity.

At present, there are two different types of injection molds known as the cold runner mold and the hot runner mold.

The hot runner system is a heating device used in injection molds to inject melt plastic into the mold cavity.

A hot runner system is an a device of heated components used in injection mold that inject melted plastic material into the cavities.

The main advantages of hot runner systems and the main developing direction of hot runner systems in the future.
