ABSTRACT:
A pouring system uses low pressure air to force molten lead into mold cavities. The pour spout is heated by the lead bath, and, preferably, a small gap is maintained between the pouring spout and a weir on the mold cavity to prevent stringers from being attached to the cast piece. At the completion of the lead pouring operation, excess metal is drained back through the spout and into the lead bath. Lead volume is controlled by adjusting pressure and timer settings, and a fill hole allows the pump to refill.
