ABSTRACT:
Force from an electrically operated ejector mechanism of a molding machine is selectably supplemented by operation of second actuators. Second actuators are advantageously fluid (hydraulic or pneumatic) operated to supplement force provided by an electrically operated primary actuator when the ejector mechanism is driven to advance ejector members into cavities of a mold assembly. The second actuators may be enabled to be operated during automatically controlled execution of a machine cycle of operation and may be operated in response to operator selections when machine operation is controlled manually.
