Product introduction :
Hot nozzle applied to hot runner, can be used independently can also increase the ring jacket, flat has a larger contact area. Mold heating ensures that the plastic plastic melt has good fluidity in the mold cavity, so the temperature of the mold directly affects the molding, quality and performance of the products to be processed. A hot runner is a heating element used in an injection mold to inject molten plastic particles into the mold cavity. Hot nozzle is divided into open hot nozzle and needle valve hot nozzle. Since the form of hot nozzle directly determines the selection of hot runner system and mold manufacturing, the hot runner system is often divided into open hot runner system and needle valve hot runner system. spring heating coil for general heating
