A cast cup can include a forward portion of a golf club head, including a hosel, forward portions of a crown, sole, heel, and toe, and a face portion or an opening to receive a face insert. A rear ring can be formed separately from the cast cup and coupled to heel and toe portions of the cast cup to form a rigid club head body, such that the club head body defines a hollow interior region, a crown opening, a sole opening, and/or face opening. The cast cup and rear ring can be made of different materials, including various metals, composites, and polymers. Composite crown, sole, and/or face inserts can be coupled to the crown, sole, and/or face openings. Weights can be coupled to the cast cup and to the rear ring. The face can have a complex variable thickness geometry.

Described herein is a tour iron having a golf club head with a faceplate, a body, and an insert. A sole, top rail, rear, and the faceplate enclose a cavity within the body. The cavity can house the insert. The insert can comprise a low-density material, allowing weight to be concentrated around the peripheral edge of the golf club head. The insert can further comprise multiple materials to improve sound and feel. The rear of the golf club head has an inflection seam running from the heel to the toe. The golf club head has an upper portion, above the inflection seam and a lower portion below the inflection seam. The lower portion can have a depth greater that the upper portion depth. The faceplate, body, and insert can be formed of different materials having different densities. The golf club head has a comparatively high moment of inertia and a low center of gravity. Other embodiments and methods are described herein.

Some embodiments include a club head with a bounded face to body yield strength ratio. Other embodiments of related club heads and methods are also disclosed.

A wood-style golf club head includes a strike face and a body that cooperate to define a hollow internal club head volume. The strike face formed from a strike plate having an outer perimeter and a frame surrounding the strike plate. The strike plate is affixed to the frame across the entire outer perimeter. The strike plate and frame define a continuous ball striking surface that has a surface texture characteristic of milling that extends continuously across both the strike plate and the frame.

A golf club head comprising two components, wherein the first component comprise a ball striking surface, a striking face return, and a sole extension with a rear mass. And wherein the second component comprises a lower density material, comprising part of the crown and part of the sole. The first component comprises a majority of the mass of the golf club head, having a rear mass comprising 20% to 35% of the mass of the golf club head.

A method of forming a golf club head that is capable improving on the inertia properties of a golf club head all while also improving the Center of Gravity (CG) location is disclosed herein. More specifically, the method forms a golf club head that achieves a relative low Moment of Inertia (MOI) about the Z-axis (MOI-Z) as well as a relatively low MOI about the Shaft-axis (MOI-SA).

Embodiments of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a golf club head includes a body portion having a face portion with a front surface and a rear surface. A first protrusion is located at the rear surface and has a first receptacle. A second protrusion is located at the rear surface and has a second receptacle. A bridge structure extends between the first protrusion and the second protrusion. The bridge structure has a first end portion received in the first receptacle and a second end portion received in the second receptacle. The first protrusion and the second protrusion maintain the bridge structure in a compressed position. The bridge structure exerts a force against the face portion. Other examples and embodiments may be described and claimed.

Embodiments of a golf club head comprising a first component and a second component that are coupled together to enclose a hollow interior are disclosed herein. The first component comprises at least a striking face, a striking face return, and a rear extension. In some embodiments, the first component also comprises a weight channel at a rear end and one or more braces that attach to the striking face return and the rear extension. The second component comprises a crown portion, a sole toe portion, and a sole heel portion. The density of the second component is less than the density of the first component. In some embodiments, the first component mass is 85% to 96% of a mass of the golf club head.

A golf club with a multi-material face is disclosed herein. More specifically, the golf club head in accordance with the present invention has a multi-material striking face portion that is made out of a backing layer having a frontal pocket, made out of titanium, and an insert, made out of a composite material, adapted to be inserted into the frontal pocket. The frontal pocket and the insert could have complementary dovetail shaped undercut features to create a mechanical bond between these two components. The insert may be bonded to the frontal pocket using an adhesive impregnated within a glass fiber weave.

Embodiments of putter golf club heads with an elastomer is enclosed herein. Other embodiments and methods may be described and claimed.
