A golf club head is described having a body defining an interior cavity and comprising a heel portion, a toe portion, and a sole portion positioned at a bottom portion of the golf club head, and a crown positioned at a top portion. The body has a forward portion and a rearward portion. A non-metallic striking surface is positioned at the forward portion of the body.

Embodiments of golf club heads, golf clubs, and methods to manufacture golf club heads and golf clubs are generally described herein. In one example, a golf club head includes a body portion having a center cavity portion, a toe-side cavity portion, a heel-side cavity portion, a first port on the body portion connected to the toe-side cavity portion, a second port on the body portion connected to the heel-side cavity portion, a first filler material in the center cavity portion, and a second filler material in the toe-side cavity portion and the heel-side cavity portion. The toe-side cavity portion is at least partially filled with the second filler material from the first port or the second port, and heel-side cavity portion is at least partially filled with the second filler material from the first port or second port. Other examples and embodiments may be described and claimed.

A golf club head includes a body having a recessed channel formed in an outer surface. A weight assembly that includes a weight at least partially disposed within the recessed channel, a cover extending at least partially over the recessed channel, and a fastener coupling the cover to the body. The fastener is adapted to retain the weight in the recessed channel only indirectly by the cover. The weight is slidably engaged with the cover and the cover is positionable in at least an unlocked configuration whereby the cover is raised at least partially out of the recessed channel and the weight is selectively slidable within the recessed channel, and a locked configuration whereby the cover is at least partially disposed within the recessed channel and the weight is secured within the recessed channel. The weight moves with the cover between the unlocked configuration and the locked configuration.

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 with an interior cavity, a face portion, a first port, and a second port connected to the interior cavity. The second port includes first and second openings, a second-port first portion, and a second-port second portion. The second-port first portion extends from the first opening to the second opening, and the second-port second portion extends from the second opening to the interior cavity. A portion of the interior cavity below a horizontal midplane of the body portion and between the second port and a heel portion edge of the body portion is closer to an outer surface of the back wall portion than the second opening of the second port. Other examples and embodiments may be described and claimed.

A multi-material golf club head having an improved performance is disclosed. More specifically, the present invention relates to a multi-material golf club head having a metallic frontal striking face portion and aft body portion with a crown opening and a sole opening that are covered by a composite crown sub-shell and a composite sole sub-shell, respectively.

Golf club components with complex structures such as lattice structures, beam structures, and complex surface-based structures, are described herein. A binder jet machine is used create complex structures within these golf club components to optimize weighting, sound, and performance of golf club heads. These components may be manufactured using a method that includes the steps of designing a golf club head component in CAD using optimization software, printing the component from a powdered material, and then removing excess powder from the component via port holes that extend into an external surface of the component and communicate with interior voids within the component.

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.
