Abstract: The present invention relates to a method for manufacturing control fingers, using metal powder injection molding. The method comprises a step of obtaining a raw material to be injection-molded by mixing metal powder and a binder; a step of forming a molded body by using a nozzle to inject the obtained raw material into a mold with a control finger shape; a step of removing grease from the molded body; a step of forming a sintered body by sintering the molded body from which the grease is removed; and a step of post-processing the sintered body. The method is provided to improve the dimensional accuracy of a control finger by using metal powder injection molding instead of casting which is a conventional manufacturing method, thereby securing high economic feasibility and to form an optimal powder composition and set up an optimal processing condition, thereby manufacturing control fingers applicable to manual transmissions used under severe conditions.
