Abstract
A manufacture method for partial structure refinement of a forged iron golf club head includes a preparing step, a first preforming step, a second preforming step, a fine-forging shaping step, a partial structure refinement step, and a final shaping step. The manufacture method is capable of partially refining the particle structure of the final workpiece. The hardness of a hitting surface of the final workpiece is reinforced to generate clear and loud sounds and to achieve better hitting performance and experience.
