    Patent number: 7797832
    Abstract: A process is provided for manufacturing aluminum vehicle wheels by a casting process that is followed by processing including flow forming and heat treatment steps while one or more risers remain on the cast wheel blank. The process can include directing cooling fluid onto an exposed surface of the casting mold to enhance wheel strength. One-by-one transfer of wheel blanks can be practiced to avoid negative aspects of batch processing.
