Abstract
The present invention relates to a method for producing a splash shield, in which method a base-portion raw material comprising a plastic, glass fibers, a compatibilizer and rubber is subjected to melt extrusion while at the same time injection molding is performed, and then, without removing the injection-molded article from the injection mold, the injection mold is rotated in the open state, and the injection-molded article is conveyed to a foaming mold and subsequently undergoes flame treatment and a polyurethane foam molding step. A single process in the production method is used for the procedure in which the materials are separately compounded and pelletized and the procedure in which the injection-molded article is molded.
