Injection Molding of Coarser Stainless Steel Powder

The injection molding of stainless steel 316 powder (-200 mesh) is studied. Through the election of materials, procedure of injection molding and properties measurement, the research work is found that it is possible to make injection molding using coarser powder(comparing with the usual injection molding powder) and to get samples with higher density, stable sintering shrinkage, better tenacity and hardness. It is feasible to produce practical parts with the method of stainless steel powder injection molding.
