BMC material is the abbreviation of Bulk (Dough) moldingcompounds, that is, bulk plastic. China is often referred to as unsaturated polyester blob plastic. The key raw materials are GF (short-cut glass fiber), UP (polyurethane resin), MD (filler calcium bicarbonate) and various additives fully mixed... read more
In the production process of SMC and BMC mold products, there is a problem that is very important, but it is also easy to handle, that is, flash processing. Since SMC is a sheet molding compound, a mixed polymer resin, the raw materials are full of glass fibers, minerals, and fillers. The BMC materi... read more
1. The silicone rubber material is in a fluid state before use, with good fluidity and filling properties. After being formulated, a rubber elastomer is formed through cross-linking reaction, which can have greater elastic deformation, and the water in the original mold has no effect on its cross-li... read more
Three, warpage deformation The main reason is the uneven curing of the molding compound and the shrinkage of the product after demolding. Generation mechanism and countermeasures: During the curing reaction of the resin, the chemical structure changes, causing volume shrinkage, and the uniformity of... read more
Everyone knows that the SMC molding process has many advantages, such as: accurate product size, smooth surface, good product appearance and size repeatability, complex structure can also be molded at one time, and secondary processing does not need to damage the product. It can be said that the SMC... read more
