<p>An improved molding apparatus and method of use thereof that inhibits unsightly blemishes that may be formed in molded plastic parts in caused by confined crevices of the molding apparatus. A mold cavity is formed by at least two mold portions and one of said mold portions has a molten plastic flow diverter positioned adjacent the confined crevice. The charge of molten plastic is injected into said cavity such that a portion of the charge of plastic flows over the diverter and into the confined crevice of the mold cavity. The diverter creates a narrow restriction adjacent the crevice such that the mold cavity has a larger cross-sectional area on either side of the diverter.</p>
