The production of BMC and SMC materials of professional.BMC is Compound Molding Bulk English acronyms, Chinese name for bmc. BMC is a semi dry process for making glass fiber reinforced molding material by intermediate thermosetting products, unsaturated polyester resin, low shrinkage and low profile additives, initiator, release agent, mineral filler pre mixed into paste, adding thickening agent, colorant, and different length of glass fiber, mixing in the special material reactor, for thickening process, and ultimately the formation of clusters of intermediate materials, can be used for injection molding and.SMC composite material, a glass steel. The main raw materials are made up of GF (special yarn), MD (packing) and various auxiliaries. It first appeared in Europe in the early 1960s, and in 1965, the process developed in the United States and Japan. At the end of 80, the advanced SMC production line and production process were introduced in China.
