CONSUMABLE MOLDING PROCESS ABSTRACT A method of preparing a charge of alloy material for use in metal casting is disclosed. Thin wall tubes consisting of one of the metallic elements of the alloy material, or an alloy of such element are provided. If an alloy tube is selected, all elements in the tube alloy must also be materials included in the over-all formulation of the alloy material. The type and quantity of the materials contained in the tubes is deducted from the quantities set forth in the over-all formula and the balance of the formula is melted and poured as a core in the tube using the tube as a mold. The resulting master charge is cut into unit charges each of a predetermined weight. These unit charges are then used in a subsequent casting operation by melting the entire unit charge to cast precision products of an alloy which consists of the mixed and alloyed materials of both the tube and the core. -1-
