The present invention, in one embodiment, provides a method for making a wood-type golf club head. The method includes the steps of: forming a face portion of the golf club head from a piece of sheet metal consisting essentially of a titanium alloy; and after forming the face portion, attaching the formed face portion to a crown and a sole of the golf club head. The step of forming the face portion includes pressing the piece of sheet metal into a die at about tons psi.

In one aspect, the invention provides a face for a golf club head. In one embodiment, the face includes an upper portion and a lower portion, wherein the lower portion has a lower toe portion located towards the toe of the golf club head, a lower heel portion located towards the heel of the golf club head, and a center portion extending from the lower toe portion to the lower heel portion, wherein the lower toe portion and the lower heel portion have a first substantially uniform thickness, the center portion and the upper portion have a second substantially uniform thickness, the second substantially uniform thickness is greater than the first substantially uniform thickness, the first substantially uniform thickness is in a range of about 0. 055 uniform thickness is in a range of about 0. 070 inches to about 0. 13 inches.

A golf club head for hitting a golf ball farther than existing golf club heads and having a sole, a crown, and a face that includes a lower portion and an upper portion. The sole and crown are cast thinner than most other club heads to promote deformation when striking a golf ball. A parabolic shaped rise in both the crown and sole provide increased lateral strength while aiding in reducing the deformation of the ball at impact. The lower portion of the face has two end portions, and a center portion with the end portions having a first thickness. The center portion and the upper portion of the face have a second thickness that is thicker than the first thickness. In addition, the face includes a channel disposed around its peripheral and having a thickness that is thinner than either the first or second thickness. The overall effect of this invention is to reduce deformation of the golf ball at impact, which reduces the energy lost as heat in the golf ball, resulting in farther drives.

A golf club head for hitting a golf ball farther than existing golf club heads and having a cast sole and a crown joined seamlessly as one piece with an opening for a face plate to be fitted into the body, and a face plate fabricated from sheet metal, precision cut by laser and precision formed in a die under extremely high pressure that includes a lower portion and an upper portion. The sole and crown part of the body are cast thinner than most other club heads to promote deformation when striking a golf ball. A parabolic shaped rise in both the crown and sole provide increased lateral strength while aiding in reducing the deformation of the ball at impact. The lower portion of the face has two end portions, and a center portion with the end portions having a first thickness. The center portion and the upper portion of the face have a second thickness that is thicker than the first thickness. In addition, the face plate is welded or bonded into a front opening of the cast body.

A ball striking face for a golf driver, fairway wood and hybrid type golf club head having a central impact area with a average thickness and additional multiple distinct areas outside the central impact area with other average face thicknesses for the improved transfer of energy to a golf ball for additional distance without any additional effort by the golfer. The striking face provides a transfer of energy at the central impact area which does not exceed CT values of 257 u sec. and an improved transfer of energy in one or more areas outside the central impact area that provides CT values greater than 257 u sec. but not greater than 275 u sec. when tested with the United States Golf Association's CT test protocol.

A driver type golf club head formed of a metal shell and having an overall volume of at least 400 cc having a geometry and weight distribution and a unique multi-level striking face that locates the center of gravity of the club head below a horizontal midline of the striking face and further locates the center of gravity behind said striking face at least 38 percent of the distance between said striking face and said rear surface or 42 mm behind the striking face.
