Golf club heads are described herein, and in one embodiment including a body with an exterior surface defining a first body volume of at least about 400 cm.sup.3. The body has a bottom portion, a top portion, a front portion, and a back portion. A face positioned at the front portion of the body and is configured to receive an impact. A top portion silhouette profile located along a perimeter of the top portion is further described. The top portion silhouette profile defines the outer bounds of the top portion in an X-direction and Y-direction. At least one indentation can be located on the bottom portion below the crown silhouette profile. The removal of the at least one indentation from the bottom portion can create a second body volume that is at least 12 cm.sup.3 larger than the first body volume.

A golf club head comprises a body having a face, a crown and a sole together defining an interior cavity. The body having a channel located on the sole and extending generally from a heel end of the body to a toe end of the body. A weight member movably positioned within the channel such that a position of the weight member within the channel is able to be adjusted, thereby adjusting a location of a center of gravity of the body. Additionally, adjustment of the weight member provides a maximum x-axis adjustment range of the position of the center of gravity (Max ΔCGx) that is greater than 2 mm and a maximum z-axis adjustment range of the center of gravity (Max ΔCGz) that is less than 2 mm.

A ball striking device, such as a golf club head, has a face with a striking surface configured for striking a ball where the face has multiple thickness regions. The face has a center region, an upper region, a lower region, a toe region, and a heel region. The upper and lower regions have a ramped thickness extending from a center region to an upper and lower edge of the face. The heel and toe regions have a constant face thickness and have a thickness less than the other regions. Additionally, the club head body has a flange where the face is welded to the club head body. The flange has a thickness that is greater than the thickness of the heel and toe regions of the face.

The present disclosure concerns embodiments of a badge and golf club head having a badge therein that can dampen the impact sound made when a hitting surface (a.k.a., face) of the golf club head impacts a golf ball. In one embodiment, a golf club head includes: a face portion surrounded by a topline portion, a toe portion, a sole portion and a heel portion, the face portion having a front striking surface and a back surface; and a badge coupled to the back surface of the face portion, the badge including a planar main body portion and at least one structural member extending outwardly from the main body portion, wherein the at least one structural member includes a lower portion and an upper portion disposed between the topline portion and lower portion, and wherein the at least one structural member has a maximum height, above the main body portion, at the lower portion and a minimum height at the upper portion.

A golf club head includes a metallic front body coupled with a rear body to define a substantially hollow structure. The metallic front body includes a strike face and a surrounding frame that extends rearward from a perimeter of the strike face. The rear body includes a crown member and a sole member coupled to the crown member. The sole member comprises a structural layer formed from a filled thermoplastic material and a fiber reinforced composite resilient layer bonded to an external surface of the structural layer. The structural layer includes a plurality of stiffening members extending from a forward portion to a rear peripheral portion of the sole member. The resilient layer can comprise a uniform thickness. The structural layer and the resilient layer each include a common thermoplastic resin component, and are directly bonded to each other without an intermediate adhesive.

Described herein is a golf club head comprising a deflection feature to increased ball speed and launch distance, while producing desirable acoustics and optimized mass distribution. The deflection feature can include any one of or any combination of an insert comprising a gap, an insert comprising voids, a thin uniform sole, a cutout in the top rail, optimized face material, a thin sole, a reinforcement device, or a multi material weight. The rear cavity insert comprises voids within the body of the insert providing a change of insert density. The faceplate comprises a reinforcement element allowing the faceplate thickness to be reduced while simultaneously reducing faceplate stress.

A golf club head includes a crown surface having an apex at a highest point and extending between the face, the rear, the heel and the toe of the golf club head. The golf club head also includes a plurality of crown turbulators projecting from the surface of the crown and located between the face and the apex, wherein each adjacent pair of crown turbulators is separate and spaced apart to define a space between the adjacent pair of crown turbulators.

A method of manufacturing a forged iron type golf club head with a cavity. The method of manufacturing comprises forming a billet into an intermediate club head body with a strike face comprising an upper region and a lower region; hot pressing a cavity into the rear portion of the intermediate body; and bending the strike face of the intermediate club head body to form a golf club head with a cavity and a planar strike face. Other embodiments are disclosed.

Embodiments of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a golf club head may have a body portion having a toe portion, a heel portion, a top portion, a sole portion, a front portion, a lead edge portion, a back portion, and an interior cavity. The golf club head may also have a polymer material partially or entirely filling the interior cavity. Other examples and embodiments may be described and claimed.

Disclosed golf club heads include a body defining an interior cavity, a striking surface, a sole, a crown, and a hosel, which is configured to provide improved aerodynamic and inertia generating properties of the golf club head. Certain embodiments include an inertia generator positioned in the sole between an area proximate the club head's center of gravity and a position toeward of the center of gravity at the rear of the golf club head. Some embodiments include fixed or removable mass elements, weights or weight assemblies positioned in the sole, including, in some instances, within or adjacent to the inertia generator. In particular embodiments, one or more weight assemblies are movably retained within a weight channel defining a path along the sole.
