금속사출성형에 의한 중합금 소결체 부품 제조에 관한 연구
여환균,김병진,김길수,김성훈,송준호,한관희 嶺南大學校 工業技術硏究所 2003 工業技術硏究所論文集 Vol.31 No.2
In this study we demonstrate that a small complex part of a tungsten-based heavy alloy (W-Ni-Cu) can be readily manufactured by utilizing the metal injection molding (MIM) technology. We use a simple thermoplastic binder system, containing low density polyethylene, paraffin wax, and stearic acid. To remove the organic binder from the molded part, we employ the solvent extraction and thermal debinding processes. Densification of debound parts is achieved by sintering in hydrogen atmosphere. The experimental results of the optimization of process variables to manufacture the heavy alloy part are described, with a brief discussion.
