ABSTRACT:
An improved composite metal-elastomer styled automotive-type wheel with a three-dimensionally contoured ornamental outboard face formed by a plastic overlay body permanently adhered or affixed to the outboard face, and an improved molding apparatus and method for constructing such a wheel. A plastic overlay body has an annular row of outboard pockets disposed in radially offset, axially overlapping relation with a annular row of inboard pockets which in turn register with vent openings in the disc to thereby provide air passages through the wheel for brake ventilation. The outboard pockets preferably are disposed radially remote from the center of the wheel close to the wheel rim, and a relatively thin cross-section of plastic material is molded so as to overlie the outboard rim flange to provide a full-face appearance to the wheel. In the method and apparatus of the invention the mold cavity is provided with perimeter air vents to enable thin cross-section molding adjacent the outer perimeter of the mold cavity.
