Hot runner system plays a significant role in the plastics industry. Hot runner molding includes nozzles, manifolds, hot runner controllers, and auxiliary components. It is also known as a hot runner controller.
The temperature controller, as a common part of injection molds, controls the heating process to ensure that the molten material flows smoothly through the runners and gates. Typically, cartridge heaters and coil heaters are installed within the manifold. Hot runner molds are easier to start because there's no need to remove solidified runners after each under-filled shot until a full mold shot is achieved and automatic cycling can begin. In hot runner systems, once the system reaches its operating temperature, the mold is ready to run.
