ABS plastic processing flow
ManufacturabilityABS is an amorphous polymer with no apparent melting point. Because of its grades, grades, in the injection molding process should be based on the different grades to formulate the appropriate process parameters, generally in 160X: above, 270C can be formed below. Because the temperature is too high, there is a tendency to destroy the rubbery phase in ABS and begin to decompose over ZTOC. In the process of molding, ABS has better thermal stability, wider range of choice, and it is difficult to degrade or decompose. Moreover, ABS melt viscosity is moderate, its fluidity is better than the polyvinyl chloride, the polycarbonate and so on, moreover, the melt cooling solidification speed is relatively quick, generally in 5 ~ 15S can be cold solid. The mobility of ABS is related to both injection temperature and injection pressure, where the injection pressure is slightly more sensitive. Therefore, in the process of forming hand from the injection pressure to reduce the melt viscosity, improving the filling performance. ABS because of the different components, the performance of different water absorbent and adhesion, the adhesion and absorption of water between 0.2 ~ 0.5% and sometimes up to 0.3 ~ 0.8%, in order to get the products ideal for the drying process, before molding, the moisture content below 0,1%. Otherwise, the surface will appear on the silver bubble,.
ABS resin is a three element copolymer developed on the basis of modification of polystyrene resin. A stands for acrylonitrile, B for butadiene, and S for styrene. ABS resin has three components, the comprehensive performance of A can improve the oil resistance, chemical corrosion resistance, which has a certain surface hardness; B ABS showed a rubbery toughness, improve impact toughness; S ABS plastics showed good fluidity, which has a good performance of thermoplastic plastic molding processing. ABS plastic is mainly used in the manufacture of instruments, instruments, household appliances, telephones, TV sets and so on. ABS plastic is used to make metal luster, and ABS is used instead of metal. Our factory produces various types of refrigerator liner and all kinds of plastic products, ABS injection products accounted for more than 88% of the total refrigerator plastic products
