Method of manufacturing an aluminum wheel
Abstract:
An improved aluminum wheel is disclosed having a two-part construction with a disc at a front position and a rim extending to a rear position. The disc comprises all the portions of the wheel that are visible from the front and thus is the only portion that is chrome-plated. The rim is formed from a double rim member that is cut at a central position to form two rims. Substantial savings in machinery, manufacturing, and material costs are realized by this arrangement.
