<p><P>PROBLEM TO BE SOLVED: To provide a golf club face plates having a variable thickness while continuing to impart higher initial velocity to a struck ball. <P>SOLUTION: A method of manufacturing a face plate for a golf club head includes the steps of providing a rolled sheet of metal material having an initial thickness and forming a blank having a prescribed outer shape from the material. The method also includes machining a second side of the blank such that the resulting face plate has a variable thickness. The machining is such that the plate has a first thickness less than or equal to the initial thickness, a second thickness less than the first thickness and a third thickness less than the second thickness. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
