Abstract
An improved process for permanently attaching an overlay to a wheel disc, wherein the overlay is aligned and spaced apart from the wheel disc. A mold is created by a combination of the overlay, wheel disc and localized nests that engage at predetermined times during foam filling to close the mold. The mold is adequately sealed so that there is no foam leakage as the foam expands to fill the mold and, therefore, no final trimming of excess foam is required. The improved process is capable of accommodating a wheel having turbine openings therein.
