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: 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.

Abstract: The invention described herein is an iron-type golf club head having an optimized mass distribution while also having the aesthetics of a full muscle-back iron. The iron-type golf club head comprises a main club head body, a lightweight, back-cavity insert, and a void within the lightweight, back-cavity insert configured to receive a CTP weight capable of adjusting mass characteristics of the iron-type golf club head.

Abstract: 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.

Abstract: Embodiments are described herein of a bifurcated heat treatment apparatus and methods for localized heat treatment of a golf club hosel or golf club head. The heat treating method comprises a bifurcated process in which the golf club head is treated in the first heating unit via induction heating and then moved to the second heating unit for convection heating. Both steps are to localize the hosel heat treatment. The heat treatment apparatus may also include a cooling component, such as a heat sink, to ensure the body of the club head remains at the correct temperature during the second heating stage when the hosel is heated in isolation. The overall bifurcated method and apparatus of the localized heat treatment leads to a hosel or golf club head with at least two different hardness values to allow for manipulation of the material without cracking or fracturing.

Abstract: Embodiments of a golf club head comprising a body having a body material density, a strike face having a strike face material density, and a coating comprising a coating material having a coating material density greater than the body material density or the strike face material density are described herein.

Abstract: Embodiments of golf club head faceplates comprising a lattice to improve the energy storage capabilities and minimize stress concentrations are described herein. The lattice can comprise a plurality of flexure shapes that facilitate in faceplate bending. The flexure shapes of the lattice can comprise a reentrant, concave, or non-convex shape. The lattice can comprise at least one repeating pattern of flexure shapes that can be interconnected or spaced apart. During golf ball impacts, the flexure shapes flex to store energy through linear and torsional bending.

Abstract: The golf club head described herein has a metal alloy strikeface formed from a faceplate having an off-axis directional grain structure. The directional grain structure can be formed of elongated grains. The faceplate can have a horizontal reference axis, extending in a heel to toe direction. The elongated grains can be angled in a longitudinal direction that is offset from the horizontal reference axis by an angle of between 5 and 85 degrees. The directional grain structure can be oriented from a low-heel region to a high-toe region of the strikeface. In some embodiments, the golf club head can have a relatively uniform characteristic time (CT) across the strikeface. Specifically, a CT differential across the strikeface can be between 0 and 7 ?s.
