Abstract
A method for delivering molten metal to a shot sleeve of a casting machine from a molten metal furnace. A molten metal pump is positioned within the furnace. The pump includes a molten metal outlet in fluid communication with the shot sleeve. A shaft and impeller or screw assembly of the pump is selectively rotated to introduce molten metal to the shot sleeve in a predetermined quantity. The predetermined quantity is determined by a controller that receives a signal from a trigger mechanism associated with the molten metal outlet.
