Sheet molding compound (sheet molding Compound) is a molding compound for dry manufacturing of unsaturated polyester fiberglass products. 
Composition of SMC Compression Mold sheet: The middle core material is composed of chopped fibers (or felt) fully impregnated with resin paste, and the upper and lower sides are covered with films. The resin paste contains various components such as unsaturated polyester resin, initiators, chemical thickeners, low shrinkage additives, fillers, mold release agents, and colorants.
The production and molding process is rough as follows: chopped raw yarn mat or glass fiber coarse fiber is laid on a film uniformly coated with resin in advance, and then another film coated with resin paste is covered on it, forming a kind of "Sandwich" structure. When it passes through the impregnation zone, the resin paste and glass fiber (or felt) are fully kneaded, and then integrated into the roll, and the necessary curing treatment is carried out.
SMC has good mechanical properties and easy processability, making it a material that has attracted much attention. SMC molding generally only takes 3 to 6 minutes, which has the advantages of saving manpower and energy, facilitating mass production, and improving product quality. In comparison with various materials, SMC is not only superior to Plastic Injection Molds such as steel and aluminum but also can compete with general thermoplastics and other reinforcing materials.
