Valve gate nozzle hot runner

system working principle

Install the hot runner nozzle and the manifold at the injection mould,keep the plastic always maintain melt condition after coming out of the injection moulding machine.Thetemperature controller box is use the thermocouple to control the temperature of nozzles and the manifold.Make the plastic maintain optimal melt condition.Thus in the hot runner system as the role of temperature control.

Valve hot runner system (valve type nozzle controller) and hot runner temperature controller can be completed with a complex injection molding process, because itself characteristic,in hot runner system, using valve hot runner system is very common.Valve hot runner system according to the different applications and structure, we can also divided it into a variety of forms like the single point needle valve hot runner system, more needle valve hot runner system, more sequence control needle valve system, order the hydraulic control needle valve system.
