SMC is a mixture of polymer resin, inert fillers, fiber reinforcement, catalysts, pigments, stabilizers, release agents, and thickeners. The glass reinforcement is between 10% and 60%, and the length is slightly longer than that of bulk molding compound (BMC).
SMC moulding process is continuous, this produces high strength, complex parts in a wide variety of sizes. Matched metal moulds are mounted in a hydraulic molding press. The material charge is or placed in the mold; the heated mold halves are closed, and up to 2,000psi of pressure is applied. Cycle time ranges from one to five minutes, depending on part size and thickness. Features such as ribs, bosses and inserts can be molded in.
Compression molded SMC parts are characterized by size and shape, two excellent finished surfaces, and outstanding part-to-part repeatability. Trimming and finishing costs are minimal.
SMC compression moulding is an advanced composite material molding method. You can use our expertise in SMC, mold design, mold build, and mold test to order the lines or toolings you need. Our customers are Mercedes Benz, Audi, GM, etc.
