Abstract of the Disclosure A casting mold is provided and has a flow path leading to a casting cavity and is positioned to receive molten metal poured from a pouring device separate from the casting mold. A wire of additive material is red into the molten metal through the flow path after a preselected volume of molten metal has been poured into the flow path and continues to be red simultaneously with the pouring of the molten metal into the flow path so that the wire meltably intermixes only with the molten metal which is poured into the flow path after the preselected volume has been reached. The feeding of the wire is stopped when the volume of molten metal poured reaches a second preselected volume while the pouring of the molten metal into the flow path is stopped when the casting cavity is filled.
