Golf club head
First Claim
1. A golf club having a shaft and a head secured to the shaft, the head comprising:
- a primary element at least partially formed of a first material, the primary element defining a first surface and an opposite second surface, the first surface providing an area for engaging a golf ball;
a cavity defined by a portion of the primary element that is of unitary construction, the cavity being positioned between the first surface and the second surface, at least a portion of the cavity extending in a direction that is substantially parallel to the first surface; and
an insert element formed of a second material and positioned within the cavity, the second material being different than the first material.

Abstract
A golf club head is disclosed that includes a primary element and an insert element formed of different materials. The insert element is located within a cavity formed by the primary element. The cavity is defined by a portion of the primary element that is of unitary construction, and the cavity is positioned between a face and a rear surface of the head. At least a portion of the cavity extends in a direction that is substantially parallel to the first surface. Another aspect of the invention involves a method of manufacturing the golf club head that includes forming the primary element. The cavity is then defined within a portion of the primary element that is of unitary construction, and the insert element is positioned within the cavity.

32. A method of manufacturing a head for a golf club, the method comprising steps of:
-
forming a primary element of the head from a metal material, the primary element exhibiting a unitary construction with a face and an opposite rear surface;
defining a cavity within the primary element, the cavity being positioned between the face and the rear surface, the cavity having a substantially constant thickness, and the cavity extending in a direction between a heel side and a toe side of the head; and
molding an insert element of the head by introducing a molten polymer material into the cavity.
