A golf club head including a striking face, a back portion, and a back cover attached to the back portion, wherein the golf club head includes damping structures and materials to achieve desired acoustic characteristics.

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 golf club head includes a body having a face plate having a strike surface and an opposing interior surface, a rear end, and a sole connecting the faceplate with the rear end. The face plate, the rear end, and the sole partially define a cavity. An insert is positioned within the cavity, the insert presenting an insert surface facing the interior surface of the face plate and spaced therefrom.

A picture with multiple slices is encoded by generating a coded slice representation for each of the slices. A slice flag is set to a first value for the first slice in the picture and corresponding slice flags of the remaining slices are set to a second defined value. A respective slice address is generated for each remaining slice to enable identification of the slice start position within the picture for the slice. A coded picture representation of the picture comprises the coded slice representations, the slice addresses and the slice flags. The slice flags enable differentiation between slices for which slice addresses are required and the slice per picture for which no slice address is needed to identify its slice start position.

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.

Summary A golf club face member is made by a manufacturing process, such as 3D printing, for a complex topology that is sturdy with good CT. 3D printing creates a face in which struts, a lattice-like structure, a waffle-iron pattern, or interior voids provide great strength and low mass. A golf club head has a club head body defining a heel portion and a toe portion and a hosel extending upward from the heel portion when the club head is at address. A face member is disposed between the heel portion and the toe portion such that it faces forward when the club head is at address. At least portion of the face member comprises a 3D printed material such as a 3D printed or sintered metal.

A co-forged iron type golf club is disclosed. More specifically, the present invention discloses a co-forged iron type golf club with the body portion made out of a first material and at least one weight adjustment portion monolithically encased within the body portion of the co-forged iron type golf club head without the need for secondary attachment or machining operations. The present invention also includes a combination of lightweight and heavy density weight adjustment portions that could be introduced towards the final forging step of the co-forging process, allowing for more flexibility in the selection of materials.

A co-forged iron type golf club is disclosed. More specifically, the present invention discloses an iron type golf club head from a pre-form billet that already contains two or more materials before the actual forging process resulting in a multi-material golf club head that doesn't require any post manufacturing operations such as machining, welding, swaging, gluing, and the like. The resultant golf club head may be capable of achieving center of gravity locations previously unachievable without utilizing this co-forging technique. The resultant golf club head may be used to create a set of golf club heads with center of gravity locations that are more advantageous throughout a set of golf clubs.
