Method of molding a plastic wheel

摘要

Methods for molding plastic wheels which are substantially free of lines of weakness in the web thereof adjacent the lug apertures. The methods generally include orienting molding gates in a molding apparatus to a desired circumferential orientation and thereafter injection molding a fiber-reinforced molding composition such that radial orientation of the fibers and/or knit lines in the molding composition, both of which create lines of weakness, are not located in the regions of the web which are radially adjacent the lug apertures.
