Abstract
Injection molding of metal powder with use of depolymerization polymers were discussed.The compound used by this process consisted essentially of PBMA(Polybutyl-methacrylate) and PS (Polystylene). It was clarified that the rate of degradation of this compound were faster than that of compound which contain a good deal of random degradation polymers (PP(Polypropylene) and EVA(Ethylene-vinyl-acetate)). On the compound which contain a good deal of depoiymerization polymers, the degree of distortion of the test piece on thermal debinding process increased with an increase of PBMA content of the compound, the sintered bodys include only 20ppm of carbon, and the relative density of sintered body was 96%.
