ABSTRACT:
A method for producing a cast aluminum vehicle wheel uses a high intensity electric infrared heating system to heat treat the wheel. The infrared heating system is an indexing-type system which includes a plurality of individual heating stations. A first group of heating stations effects solution heat treating of the wheel, while a second group effects artificial aging. The infrared system enables the solution heat treating and aging to be completed in less than 15 minutes.
