Abstract: Embodiments of golf club heads with cavities and methods to manufacture golf club heads with cavities are generally described herein. Some embodiments include a golf club head comprising a body. The body comprises a strikeface, a backside of the strikeface, a heel region, a toe region opposite the heel region, a sole, and a rear portion opposite the strikeface. In many embodiments, the body further comprises a first cavity at the backside of the strikeface and located between the strikeface and the rear portion, and a second cavity at the rear portion. In some embodiments, the first cavity and the second cavity are directly coupled to each other to form a single, aggregate cavity. Other embodiments may be described and claimed.

Abstract: A golf club head includes a body and a face plate insert. The body includes an annular face support having a recessed shelf configured to receive the face plate insert, and partially defining a central cavity. The face plate insert includes a hitting surface and a rear surface that is opposite the hitting surface. The face plate insert is disposed within the annular face such that the rear surface of the face plate insert abuts the recessed shelf. The face plate insert includes a polymeric material that is disposed across the cavity and that has a tensile strength of at least about 220 MPa.

Abstract: In general, aspects of this invention relate to golf clubs or golf club components incorporating adjustment members that permit ready adjustability of golf club parameters and/or interchangeability of golf club components to change a golf club configuration, and methods for providing golf clubs. According to aspects of this invention, an adjustment member may be utilized to allow the adjustability of a golf club parameter to change a golf club configuration, while ensuring there is substantially no change to other club or club head variables, parameters or characteristics. According to another aspect of this invention, an adjustment member may be utilized to allow the adjustability of two golf club parameters independently to change a golf club configuration, while ensuring there is substantially no change to other club or club head variables, parameters or characteristics.

Abstract: 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.

Abstract: Some embodiments include a reinforced face of a club head. Other embodiments for related reinforced faces of club heads and related methods are also disclosed.

Abstract: Embodiments of golf club face plates with internal cell lattices are presented herein. Other examples and related methods are also disclosed herein.

Abstract: Aspects of this disclosure relate to a golf club head which includes a wood type golf club head body including a ball striking face portion at a front side thereof, a rear side opposite the front side, a crown portion, and a sole portion. Further, the sole or crown or rear portion of the golf club head body may be configured so that the golf club head body includes a bump portion which protrudes from the sole or crown or rear portion and an indented portion which recedes into the sole or crown or rear portion and creates a recess in the sole or crown or rear portion of the golf club head body. Further, the bump portion and the indented portion may be configured so that a center of gravity of the club head body is nearer to one of the heel edge of the club head body and the toe edge of the club head body.

Abstract: The invention is a golf club head with a strike face including a first elongated channel and a second elongated channel which both extend from a top-to-bottom center line of the striking face toward the heel edge and the toe edge of the strike face. The channels can be filled with a fill material, for example a polymer, and a groove may be defined in the strike face or in the fill material of one or more of the channels. The height of the channels, the hardness of the fill material, and the positioning of the groove can all affect the performance of the golf club head. In some embodiments, the golf club head is a putter-type club head.

Abstract: In general, aspects of this invention relate to blade-type iron golf clubs or golf club heads. The blade-type golf club head may comprise a body forged of a metal material. The body may include a hosel, a top surface, a sole, a heel, a toe, a ball striking surface, and a rear surface opposite the ball striking surface. The rear surface may have recess in which a dual-density insert is affixed. The dual-density insert may have a first portion or first insert with a density greater than a second portion or second insert with a lesser density located closer to the toe than the first portion or first insert located closer to the heel. The mass distribution of the dual-density insert moves the center of gravity of the club head closer or substantially coincident to the face center location.

Abstract: The invention is an alternative fitting system for golf clubs including a adapted production head with a threaded hosel and a shaft sleeve adapter and a compression nut. The shaft sleeve adapter is permanently adhered to a golf club shaft. The compression nut holds together the shaft sleeve adapter and the threaded hosel of the club head. Alignment notches on the threaded hosel and alignment features on the shaft sleeve adapter prevent unwanted rotation. Furthermore, some embodiments of the shaft sleeve adapter comprise an angled bore hole, which allows for various loft and lie configurations.

Abstract: Embodiments of golf clubs with adjustable loft and lie and methods of manufacturing golf clubs with adjustable loft and lie are generally described herein. The invention relates in particular to a golf club head with an adjustment portion that allows a user to change the loft and lie. The separate adjustment portions of the club head can couple the upper hosel to the body at a plurality of positions. An insert part of the adjustment portion has an upper section for receiving the upper hosel portion, a middle section, and a lower hosel portion. The sections of the adjustment portion can be coupled together by a fastener so that the sections are rotationally moveable.

Abstract: A method of forming a golf club head assembly includes aligning a faceplate with a recess of a club head; welding the faceplate to the club head; then, after welding the faceplate, heating the club head and the faceplate to at least a solvus temperature of the faceplate for a predetermined amount of time; and then, after heating the club head and the faceplate, allowing the club head and the faceplate to air cool.

Abstract: A golf club head includes a club face and a body. The club face is formed from a metallic material and includes a first, hitting surface, a second, rear surface that is opposite the first surface, and a flange that is separated from the second surface by a transverse distance. The body is formed from a polymeric material and includes a crown, a sole, a hosel, and a face support. The club face and the body cooperate to define a closed volume, and the face support extends to opposing sides of the flange and is operative to couple the club face to the body.

Abstract: Embodiments of golf club face plates with internal cell lattices are presented herein. Other examples and related methods are also disclosed herein.

Abstract: Golf club heads (e.g., drivers, fairway woods, wood-type hybrid clubs, or the like) according to at least some example aspects of this invention include a striking face and a rear portion opposite the striking face, the rear portion defining an opening to an interior cavity. A rear body member configured to be inserted into the opening is engaged with the rear portion of the club head. The rear body member may include multiple rear body parts that may be removable and/or interchangeable to permit flexibility in controlling the weight distribution of the golf club head.

Abstract: A golf club head including a club face defined by a toe end, a heel end, a top rail and a sole. The golf club head including a plurality of grooves disposed on the club face between the top rail and the sole. Each groove extends between the toe end and the heel end. Widths of the grooves vary in a direction extending between the heel end and the toe end.
