  • Patent number: 7131912
    Abstract: 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 70 tons psi.

  • Patent number: 6659884
    Abstract: 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.

  • Patent number: 6659885
    Abstract: 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.
