Abstract:
A method and equipment for manufacturing a light metal vehicle wheel that has a rim drop base and a club-shaped thickened portion extending axially outward. The club-shaped portion has a tread on its outside surface for use in case of flat tire and has rim horns at its outer end. The method and equipment include pressing the rim horns radially inward by compression rings of a mold die. A radial inner surface of the club-shaped thickened portion is machined by chip removal so as to form an undercut next to the rim horn.
