Abstract: A method of manufacturing an end plated for a fuel cell stack, using overmolding injection molding is provided. The method prevents damage to tapped portions in injection molding and re-tapping after the injection molding, by implementing a method of injection molding for an end plate that prevents an injection-molded part from flowing into taps by forming a male thread on a first side of each of fixing pins fitted in a metal insert in injection molding of an end plate and by fastening the fixing pins in advance in the taps of the metal insert. In addition, the method aligns the metal insert at the more accurate position while a mold is assembled, by tapering the second sides of the fixing pins.
