Abstract
To provide a method for forming undercuts of a metal injection molded product by simple processes and metal injection molded products having undercuts formed by the forming method thereof, steps are included of injection-molding a feed stock containing metal powder and binding resin, forming undercuts to an injection green body obtained by the injection-molding, and sintering after debinding the injection green body formed with undercuts. It is preferable that undercuts are formed by deforming at least one part of an injection green body; it is more preferable that they are deformed by pressing with a pressing member.
