In the metal injection molding process, fluidity of the compound with metal powder and binder is very important factor for molding without defects. In this paper, the effects of molding condisions (injection temperature and rate) on the moldability and the mechanical properties of compacts have been investigated by means of flow test and tensile test. The compound consisted of a carbonyl iron powder and a multicomponent wax-polymer binder. Two different types of the binder were used for this
