Abstract
The testing of metal injection molding of SUS316L powders using a PE (polyethylene)-PP (polypropyrene)-sesame oil binder system was carried out. When the green parts were immersed in a THF (tetrahydrofuran) solvent at 50°C for 2hr, the sesame oil was all extracted. The residual parts were debound in nitrogen gas. The debound parts were sintered at 1320°C in vacuum for 1hr. The relative density of the sintered specimen was 95.1%. The carbon and oxygen contents of the sintered specimen were 0.001wt% and 0.03wt%.
