ABSTRACT:
A valve gated injection molding system having an elongated valve member with an integral electrical heating element received in each nozzle to provide additional heat. An actuating mechanism engages the rear end of the valve member to reciprocate it between a withdrawn open position and a forward closed position. The valve member has a head which projects rearwardly from the nozzle. The heating element has an external terminal which extends outwardly from the head through a slot in a mounting sleeve. Thus, access for connection of an electrical lead to the moving terminal is provided between the fixed nozzle and the fixed cylinder of the actuating mechanism.
