SMC (Sheet Molding Compound) and DMC (Dough Molding Compound) are ready-to-mold composite materials made from polyester resin reinforced with glass fibers and fillers. These materials are commonly used in compression and injection molding processes to manufacture durable, heat-resistant, and electrically insulated components.
SMC and DMC both materials offer excellent dimensional stability, high strength, and surface finish quality, making them ideal for mass production in automotive, electrical, and industrial applications.
SMC is a sheet-form material consisting of chopped glass fiber mats impregnated with a thickened polyester resin paste. It is stored in rolls and cut into required sizes before molding.
DMC, on the other hand, is a thick, dough-like material also made of resin, glass fiber, and additives. It is supplied inbulk form and used directly for molding.
Both materials offer excellent dimensional stability, high strength, and surface finish quality, making them ideal for mass production in automotive, electrical, and industrial applications.
