Evaluation of Particle Size Effect of 17-4 PH Stainless Steel and 316L Stainless Steel in Powder Injection Molding

摘要

The particle size effect of 17-4 PH and 316L stainless steel powder was investigated for the powder injection molding process. The mean particle sizes used were 8, 4, and 3 μm. The parameters considered were solids loading, processing conditions and mechanical properties with respect to particle size. After a basic PIM optimization study, the investigation concerned micro-features manufactured by means of the powder injection molding in terms of feature size and dimensional consistency. The application is micro components for dental devices.
