A hot runner system is an assembly of heated components used in plastic injection molds that inject molten plastic into the cavities of the mold. (The cavities are the part of the mold shaped like the parts to be produced.) By contrast, a cold runner is simply a channel formed between the two halves of the …
Valve Gate The valve gate adds a valve rod to the hot runner gate. The valve can be activated to close the gate just before material near the gate solidifies. This allows a larger gate diameter and smoothes over the gate scar. Since the valve rod controls the packing cycle, better control of the packing …
