Abstract
An automotive wheel and a method for manufacturing, in which a center hub is formed using drawing and stamping methods, is disclosed. A mounting foot is spin forged onto the edge portion of the formed center hub, and the center hub is then polished and mounted into a separately formed cylindrical rim. The resulting automotive wheel has the look of a machined billet-type automotive wheel but with a substantial reduction in wasted material and corresponding cost.
