Abstract
A lost foam metal casting process employs a chill member to reduce porosity within a region of a product casting. The chill is adhesively bonded to a fugitive pattern prior to jointly embedding within a particulate sand mold by fluidization, thereby conveniently and reliably arranging the chill and the pattern within the mold for casting.
