Method for producing forged face member 60 for a golf club. The forging process (Fig 8) includes multiple heating and pressing stages to obtain face member 60. Heating temperature is always below 1000 degrees C, lasting for less than 20 minutes. After the first heating and pressing stage, a metal bar is formed into a L-shaped metal bar. After the second heating and pressing stage, an intermediate face member is formed. This is then coated with a glazing compound. After the coated intermediate face member has been heated and pressed, final face member 60 is formed. Preferably the heating should take place at less than 950 deg. C for less than 16 minutes. The face member 60 may have extension 74 extending laterally along the entire perimeter of striking plate 72. There may also be a final processing stage where face member 60 is heated to less than 600 deg. C for less than 25 minutes before being pressed at low pressure to ensure proper bulge and roll. The metal may be titanium, a titanium alloy, stainless steel or steel. Striking plate 72 may have concentric regions of varying thickness, the thickest part being in the centre. |
