Cold runner features:1.The flow channel adopts an open form to ensure the flow channel is smooth without dead corners, which is convenient for cleaning and maintenance;
2.The cold runner generally adopts a cold half mold system with a pneumatic valve needle cold nozzle, which provides advantages for the manufacture of silicone injection molding molds, saving time and improving efficiency;
3.Fewer casting systems, shorter molding cycles, less material loss and more material savings;
4.The water path of each cold nozzle can be controlled separately, in order to ensure that the temperature of each cold nozzle is consistent;
5.The valve needle and valve sleeve are made of imported steel and special processing technology, which is more wear-resistant and corrosion-resistant, reducing the risk of stuck needles and material leakage.
