PRODUCTION METHOD FOR A SPLASH SHIELD USING A CONTINUOUS EXTRUSION-INJECTION-FOAMING MOULDING PROCESS

摘要

The present invention relates to a production method for a splash shield using a continuous extrusion-injection-foaming process, and more specifically 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. In the production method for a splash shield according to the present invention, a single process 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 and a foamed body is molded, and thus it is possible to curtail the conveying of materials and various component parts and to reduce the risk of molding dimension errors and of denaturing and contamination in the conveying procedure.
