Abstract:
A method for manufacturing an insert having a plurality of tabs thereon in a cast molding operation is disclosed herein. The method commences with mixing a polyurethane prepolymer with a curing agent to form a polyurethane. The mixture is then poured into a mold cavity having a plurality of peripheral cavities. The mold is then subjected to pressure and heat for a predetermined time to cure the mixture thereby forming the polyurethane insert.
Abstract:
A method for manufacturing a golf club head with a face component composed of a plurality of plies of pre-preg material and having a striking plate portion with a thickness in the range of 0.010 to 0.250 inches is disclosed herein. The golf club also has a crown component composed of a plurality of plies of pre-preg material and a sole component composed of a plurality of plies of pre-preg material. The golf club head is manufactured using a bladder compression molding process.
Abstract:
A high moment of inertia golf club head composed of a composite material and having a weight strip in a ribbon section is disclosed herein. The weight strip may be composed of copper, tungsten or a similar metal. The moment of inertia, Izz, of the golf club head about a vertical axis Z through the center of gravity ranges from 2800 g-cm2 to 5000 g-cm2, and a moment of inertia, Iyy, about a horizontal axis Y through the center of gravity of the golf club head ranges from 1900 g-cm2 to 2500 g-cm2. The golf club head is preferably composed of plies of pre-peg sheets. The volume of the composite golf club head varies from 300 cm3 to 600 cm3.
Abstract:
A golf club having a club head composed of a composite material and having an enhanced sound during impact with a golf ball. The golf club head also has a coefficient of restitution greater than 0.8 under test conditions such as the USGA test conditions specified pursuant to Rule 4—1e, Appendix II, of the Rules of Golf for 1998-1999. The golf club head body has a weight strip placed within a ribbon of the body. The sound of the composite golf club head during impact with a golf ball is approximately equivalent to that of a metal wood during impact with a golf ball. The composite golf club head of the present invention has a combined sound level greater than one hundred seventeen decibels during impact with a golf ball.
Abstract:
A golf club (40) having a club head (42) with a face component (60) and an aft-body (61) is disclosed herein. The face component (60) has a striking plate portion (72) and a return portion (74). The aft-body (61) is composed of a crown portion (62), a sole portion (64) and optionally a ribbon section (90). The face component (60) is composed of a metal material, and the aft-body (61) is composed of a non-metal material such as a composite material or a thermoplastic material. The striking plate portion (72) preferably has an aspect ratio less than 1.7. The striking plate portion (72) preferably has concentric regions of thickness with the thickness portion in the center (102). The club head (42) has a volume in the range of 300 cubic centimeters to 600 cubic centimeters, a weight in the range of 165 grams to 300 grams, and a striking plate portion (72) surface area in the range of 4.00 square inches to 7.50 square inches. The golf club head (42) has a coefficient of restitution greater than 0.81 under test such as the USGA test conditions specified pursuant to Rule 4-1e, Appendix II, of the Rules of Golf for 1998-1999.
Abstract:
The golf club (20) of the present invention allows for the face angle of the golf club to be set after manufacturing of the golf club head (22). The golf club (20) of the present invention is able to accomplish this by providing a golf club head (22) with an internal hosel (38) (such as a GREAT BIG BERTHA® HAWK EYE® driver), a shaft (40) and an insert (51) that is disposed within the internal hosel (38). The insert (51) allows for the face angle of the golf club (20) to be oriented after manufacturing of the golf club head (22). The golf club (20) may also include a hosel liner (50) that is disposed within the insert (51).
Abstract:
A golf club having a club head with a striking plate having a thickness in the range of 0.010 to 0.250 inch is disclosed herein. The club head may be composed of three pieces, a face, a sole and a crown. Each of the pieces may be composed of a titanium material. The striking plate of the club head may have an aspect ratio less than 1.7. The striking plate may also have concentric regions of thickness with the thickness portion in the center. The club head may be composed of a titanium material, have a volume in the range of 175 cubic centimeters to 400 cubic centimeters, a weight in the range of 165 grams to 300 grams, and a striking plate surface area in the range of 4.00 square inches to 7.50 square inches. The golf club head may also have a coefficient of restitution greater than 0.8 under test conditions such as the USGA test conditions specified pursuant to Rule 4-1e, Appendix 11, of the Rules of Golf for 1998-1999.
