1. MALLEABLE INSPECTION STATION WHERE WORKERS ELIMINATE MALFORMED CASTINGS AND SEPARATED GOOD CASTINGS PRIOR TO ANNEALING.
2. NIAGARA SHEAR CUTTING MACHINES USED TO SHEAR GATES AND REMAINING EXCESS METAL OFF OF ANNEALED MALLEABLE CASTINGS.
3. AUTOMATED MALLEABLE ANNEALING OVENS SLOWLY HEAT AND COOL CASTINGS AS THEY MOVE IN BINS ALONG TRACKS IN THE OVEN BOTTOM IN THE MALLEABLE ANNEALING BUILDING. THIS PROCESS TRANSFORMS BRITTLE WHITE IRON CASTINGS INTO SOFTER, STRONGER MALLEABLE IRON.
4. QUENCHING TUMBLING MILL TUMBLES CASTINGS OVER EACH OTHER TO REMOVE RUNNERS AND SPRUES WHILE QUICKLY COOLING THEM WITH WATER IN THE MALLEABLE ANNEALING BUILDING. THIS PROCESS ENSURES CASTINGS FORM WHITE IRON PRIOR TO BEING ASSEMBLED.
