MIM manufacturing process for non-magnetic 17-4P stainless steel parts

The invention discloses an MIM manufacturing process for non-magnetic 17-4P stainless steel parts. The MIM manufacturing process comprises the following steps: putting a 17-4PH stainless steel powder and a binder into a kneading machine for mixing; cooling to a room temperature and then crushing by using a crusher, and then extruding a crushed material for pelletizing in an injection molding machine; processing a prepared feeding material in the injection molding machine into blanks; then catalyzing, debinding and removing polyformaldehyde from the injection blanks in a catalytic debinding furnace; putting well catalyzed and debound blanks into a vacuum furnace for debinding and sintering; and carrying out solution treatment on well sintered parts in a shielding gas protected continuous furnace or the vacuum furnace. The MIM manufacturing process provided by the invention adopts an MIM process and uses a 17-4PH powder sintered through nitrogen, and then the non-magnetic MIM metal parts with good compactness a
