ABS PLASTIC INJECTION MOLDING
ABS is a thermoplastic polymer. It has an amorphous structure and melts temperature between 190 and 270oC. But it is injection molded between 40 and 80oC. A terpolymer of acrylonitrile, butadiene, and styrene produced by emulsion polymerization. It is a low cost, high impact resistant, and lightweight. It has an average density of 1.07g/m3. It can withstand an impact of 200 -215J/m. ABS is a low-cost material.
