SMC plastic box is a new switch box, SMC environmental protection material, protection class up to IP66. The SMC itself is reinforced by mixing 30% glass fiber so that it achieves a high resistance and mechanical stiffness (IK09) and a weight of about 1/3 of the metal box. Compared with the metal box, this series has the characteristics of lighter weight, more adaptable to corrosion and moist environment. At the same time its price can be equivalent to the iron box.
SMC composite material is the abbreviation of Sheet molding compound, namely sheet molding compound. The main raw material consists of GF (special yarn), UP (unsaturated resin), low shrinkage additives, MD (filler) and various additives. It first appeared in Europe in the early 1960s. Around 1965, the United States and Japan successively developed this process. In the late 1980s, China introduced advanced SMC production lines and production processes.
