Production method for a splash shield using a continuous extrusion-injection-foaming moulding process

A method of fabricating a splash shield using a continuous extrusion-injection-foaming process, comprising:

• introducing raw materials for a base comprising a plastic material, glass fibers, a compatibilizer, and rubber comprising a polyolefin elastomer, into an extruder and extruding a resin mixture by melting and mixing the raw materials;
• conveying the extruded resin mixture in a molten state and injection-molding the extruded resin mixture;
• rotating the injection mold in an open state without removing an injection-molded resin mixture from an injection mold and conveying the injection-molded resin mixture to a foaming mold;
• performing flame treatment on the resin mixture in the foaming mold;
• and
• foaming polyurethane on a surface of the flame-treated resin mixture, with the foaming mold closed;
• wherein the raw materials for the base comprise about 60 to about 80 wt % of the plastic material, about 15 to about 30 wt % of the glass fibers, about 1 to about 5 wt % of the compatibilizer, and about 3 to about 8 wt % of the rubber.
