Abstract
The present invention resides in a golf club head having a high COR that is durable and has desirable acoustic qualities. The club head includes a body portion, a striking face and a crown forming a hollow cavity of at least 150 cc in volume. The crown is secured to the body portion, enclosing an upper opening. A surface veil may also be provided about a junction of the crown and body. The crown has a maximum thickness no greater than about 2 mm. The density of the crown is less than the density of the body portion. The golf club head has a maximum coefficient of restitution of at least 0.80.
Claims13
A method of manufacturing a hollow golf club head comprising:
- forming a body of a metal material, the body having a sole, a front defining a front opening, a top portion defining an upper opening and a side portion, the side portion extending rearward of the front opening and having a toe, rear, and heel regions, wherein the body is comprised of a metallic material having a density of at least about 4 g/cc, and the body includes a shoulder disposed around the periphery of the upper opening and a recessed support extending from the shoulder and positioned adjacent to the upper opening;
- forming a striking plate adapted to be secured to the body and enclose the front opening, the striking plate having a thickness in the range of 1.5 mm to 4 mm;
- welding the striking plate to the body portion, the striking plate having at least one flat portion and at least one tapered portion on a rear surface of the striking plate;
- forming a crown of a material having a density less than a density of the body, the crown having a maximum thickness no greater than 2 mm, the crown adapted to be secured to the body;
- securely attaching the crown to the body to enclose the upper opening with an edge of the crown set in the recessed support of the top portion;
- and disposing a veil between the edge of the crown and the shoulder, wherein the veil covers an entire edge and entire upper surface of the crown;
- wherein at least the crown is attached by adhesive bonding to the upper opening in the body, the golf club head having a maximum coefficient of restitution of at least 0.80 and a volume of at least about 150 cc.
