ABSTRACT:
This invention relates to the production casting of molten metal. In such casting, the molten metal being poured into one cavity may be splashed or overflowed into another adjacent cavity. The invention provides a splash guard which defines a barrier to the molten metal and prevents such inadvertent introduction of the molten metal into an adjacent cavity. The splash guard preferably comprises a substantially solid object made of a material, such as graphite, that retains its structural integrity at high temperatures and upon contact with molten metal, but which does not strongly adhere or bond to the molten metal upon cooling. The invention can be embodied in both manual and automatic casting lines. In a manual casting line, the splash guard may physically contact a surface of the mold to create the molten metal barrier between the cavities. In an automated casting line, the splash guard may be raised above the mold surface, and form the molten metal barrier through use of the surface tension of the molten metal, so as to avoid interference with the weighing scales on the automated pouring device.
