Valve Gate Hot Runner factory
Valve gate hot runner system is simply a hot runner that closes and opens the glue outlet by moving the valve needle. The needle valve hot runner is that after injection molding, the needle in the nozzle hole will move forward through the valve, so as to block the nozzle, so that the glue can not be shot again, and the glue in the cavity can not be returned. This hot runner does not need to clean into the glue point, because it is very smooth.
