Abstract: A golf club head with sound tuning composite members forming at least a portion of the surface of the golf club head is disclosed herein. The composite members being a composite layer made out of a sandwiched core layer that is interposed inside the midsection of the composite member to provide vibration damping and sound tuning characteristics.

Abstract: A hollow golf club head with a concave portion is disclosed and claimed. The club head includes a metallic portion and a light weight portion, which may be formed of plastic, composite, or the like. The concave portion allows the club designer to make a club head having very thin portions while still maintaining the requisite structural integrity. Convex bulges may optionally be provided to house weight inserts to enhance the playing characteristics of the golf club.

Abstract: The present invention relates to a method for forming golf club head using metal injection molding and the resulting golf club head. The method of the invention allows for a lower volume of powdered metal than current metal injection molding processes thereby decreasing overall production cost.

Abstract: The present invention relates to a golf club head provided with a shell defining an inner cavity and having a face and a body. The face has a first or reinforcement portion with a first thickness and a second or remaining portion with a second thickness less than the first thickness. The reinforcement portion is located at the center of the face. In one embodiment, the exterior surface of the face defines at least one groove spaced from the center of the face.

Abstract: A hollow golf club head with a concave portion is disclosed and claimed. The club head includes a metallic portion and a light-weight portion, which may be formed of plastic, composite, or the like. The concave portion allows the club designer to make a club head having very thin portions while still maintaining the requisite structural integrity. Convex bulges may optionally be provided to house weight inserts to enhance the playing characteristics of the golf club. The metallic portion of the club head may take on the appearance of a frame, into which several light-weight inserts are positioned. These light-weight inserts may be positioned in the crown, skirt, and sole of the club head. The club head is thus contoured such that its surface area is substantially large. The club head may also be formed of a single, relatively light-weight material.

Abstract: A method for making golf club heads includes using direct metal laser sintering (DMLS), selective laser melting (SLM) and other computer controlled high energy sintering or melting techniques to form club heads with customized user parameters. The powdered metals can be selected by type and quantity to achieve a desired density or weight distribution. Club heads made by these techniques are characterized by having customized parameters chosen for individual golfers. By sintering powdered metal to form areas of different porosity, club heads with desired weight distributions can be achieved.

Abstract: A golf club head is disclosed. The golf club head includes a first body member and a second body member. The first body member includes a strike face and a top portion. The second body member is coupled to the first body member and extends away from the first body member in a direction opposite the strike face. At least a top portion of the second body member is camouflaged. A preferred method of camouflage is color differentiation, wherein the second body member is darker than the first body member. Specific color values and club head geometries are also disclosed and claimed. The club head may include a body member and a weight member such as a bar that extends rearward from the body member. A cover may be included to camouflage the weight member. A separate core member and high visibility sight lines may also be provided.

These light-weight inserts may be positioned in the crown, skirt, and sole of the club head. The club head may be formed by co-molding, eliminating the need for welding or adhesives, freeing mass to be used in more beneficial ways. The club head may be large to increase playability and forgiveness.

Abstract: The present invention is directed at a quick release connection system to facilitate customization of golf clubs. It can be used to interchange shafts, removable weights, or soleplates quickly and easily. Teeth are disposed on the inside of a frame so that a shaft may be inserted with minimal resistance, but cannot be removed without specific steps which may require the use of a simple tool. Strengthening and interlock devices are provided to ensure performance quality akin to tradition al golf clubs.

Abstract: A golf club head with sound tuning. The golf club head includes a hollow body that defines an interior cavity and at least one tuning member extends across the interior cavity. The tuning member dimensions, stiffness and dampening characteristics are selected to alter the vibration behavior of the golf club head.

Abstract: A weight adjusting structure of a golf club head comprises a 360-degree rotatable rotary table installed in a body of a golf club head, wherein the rotary table is combined with an incomplete annular weight block at a peripheral portion on an arbitrary side thereof, so that the rotary table and the weight block form a rotary table assembly whose weight orientation can be adjusted. The weighted rotary table assembly installed in the body of the golf club head can be used to adjust a distribution of different weights around 360 degrees, whereby a preferred location of the club head's gravity center can be set according to a golfer's swing posture and a location of the club head's gravity center the golfer is used to.

Abstract: A golf club head having a deep undercut is disclosed and claimed. The club head includes a cavity in a back portion thereof, opposite the striking face. A recess is provided in the back portion of the club head in proximity of the heel and, optionally, the sole. The recess may extend to the hosel bore, and may be separate from the cavity. An insert, such as a dampening member, a weight member, or a combination thereof, may be positioned within the recess. The recess and any insert provided therein alter the club head moment of inertia and center of gravity location, providing an improved feel to the golf club.

Abstract: A golf club head formed of multiple materials is disclosed. Those portions of the club head that are subject to high stresses during normal use of the golf club head are formed of a metallic material. Most of the material beyond what is required to maintain structural integrity, however, is removed and replaced with a lightweight material. This freed-up mass that can be redistributed to other, more beneficial locations of the club head. The lightweight material also damps vibrations generated during use of the golf club. This vibration damper may be retained in a state of compression to enhance the vibration damping. One or more weight members may be included to obtain desired center of gravity position, moments of inertia, and other club head attributes. A insert formed of multiple materials and having regions of varying thickness may also be included on a rear surface of the club head.

Abstract: A composite material golf club head is provided having a body made from a first metal and a face insert press fitted to a portion of the body and made from a second metal. The metals are chosen so that the first metal is heavier than the second metal. The second metal is disposed towards the front and top of the body, and is preferably hard-anodized. In addition, an interlocking structure, for example rectangular or dove tail shaped channels, is provided in the body so that the face insert becomes embedded in the interlocking structure to anchor the face insert to the body. Portions of the golf club head, such as the face insert or sole plate, are anodized to protect against corrosion. The anodized coating is colored to improve aesthetic characteristics or infused with a polymer to increase or reduce friction.

Abstract: Disclosed herein is a golf club head having a body portion and a face insert. The front of the body portion further comprises a cutout sized and dimensioned to receive the face insert. The body portion is preferably made from a high-strength metal such as stainless steel, titanium or titanium alloy. The face insert is preferably comprised of a metal having a lower density than that of the body portion. The face insert comprises an aluminum metal matrix composite (MMC) containing an amount of scandium and zirconium. The golf club head may also include a top line insert made of a lightweight material and at least one heavy weight member disposed to the back of the club head.
