ABSTRACT:
A gas assisted injection molding system includes a gas injection pin and gas vent pin which are independently, selectively extendable into a cavity of a mold. Each of the gas injection pin and gas vent pin include a first actuator and a second actuator. Each first actuator selectively extends and retracts the pin into and out of the cavity of the mold. Each of the second actuators selectively opens and closes a valve within the pin, thereby selectively permitting and restricting the flow of gas through the pin.
