Injection molding of metal powder with use of POM(polyacetal) was discussed.
The compound on this process consisted essentially of POM and depolymerization polymers. It was clearly that the rate of degradation of the compound which contains a good deal of polyacetal was faster than that of which contains a good deal of other depolymerization polymers (PBMA and PS) or random degradation polymers (PP(polypropylene) and EVA (Ethylene-vinyl-acetate)). On thermal debinding process, the degree of distortion of the test piece which contains a good deal of POM was smaller than that of the test piece of which contains a good deal of PP, and the sintered bodys contained the only 30 ppm carbon. The relative density of sintered body was 96%.
