ABSTRACT:
A molten metal metering and transfer device for use with a molding machine and a bath for holding and heating molten metal includes an elongate container which is supported in the bath with one end extending out of the bath and the other extending into the bath. An entry port is formed in the side of the container to allow molten metal to flow into the container and an exit port is formed in the container adjacent the top and above the bath. A uniquely formed plunger seated in the container moves downward into the bath, then upward out of the bath, trapping a predetermined amount of molten metal above its top surface. The formation of the plunger facilitates flow of the molten metal out of the container when the plunger reaches the exit port.
