An object of the present invention is to provide a method of manufacturing a golf iron head which is different from the conventional one, to enhance the effect of combining the plate and the head body, and to reduce the damage ratio during manufacturing. That is, the method for manufacturing the golf iron head of the present invention utilizes the pressure contact area of the mold and the change of the pressure point. After the next rolling, the plate is deformed by a strong pressure and the periphery of the plate is fitted into the deep penetration tank of the head body. Then, through the slightly larger area of the second mold and the pressure point, the plate is pressed sufficiently to join the head body more tightly. Further, the milling machine is used to cut the surface flat, and the CNC engraving machine is again used to engrave score lines on the plate, and after buffing, the process is completed.
