ABSTRACT:
A clamp actuator of a molding system is provided. The clamp actuator includes a first actuator configured to be interactable with a rod; and a second actuator configured to be interactable with the first actuator. The first actuator is configured to apply a clamping force to the rod; and the second actuator is configured to apply a force opposing the clamping force to the first actuator. Responsive to actuating the first actuator, the rod is drivable between (i) a home position in which a clamping force is not applicable to the rod, and (ii) a force application position in which the clamping force is applicable to the rod. Responsive to a mold flash occurring which exceeds the clamping force, the rod is moveable into a mold flash position beyond the home position.
