The ball striking panel 20 is provided with an integrally formed ring wall 21 and a bent portion 22 . The ball hitting panel 20 can expand the effective hitting area to the maximum through the ring wall 21 and the bending part 22, and use the bending part 22 to limit and delay the transmission of the ball hitting stress, so that the ball hitting panel 20 can immediately complete the maximum The amount of elastic deformation to obtain a higher coefficient of elastic recovery (coefficient of restitution, COR), and make the iron-type club head suitable for long-distance shots. However, when mass-producing the batting panel 20 with the surrounding wall 21 by traditional precision casting, the batting panel 20 is likely to form irregular slag holes, shrinkage cavities, sand holes or pores during the manufacturing process, thereby affecting the structure. strength and reduce the qualified rate of its finished products. Furthermore, the mechanical properties of the bent portion 22 of the ball striking panel 20 made by precision casting are relatively insufficient.
