A golf club head includes a golf club head main body having a toe, a heel opposite the toe, a sole, and a top portion opposite the sole. The golf club head further includes a striking face having a face center. The striking face includes a central region including the face center, a first average thickness, and a variable thickness. An upper region above the central region has a second average thickness and a toe region toe-ward of the central region has a third average thickness. An intermediate region at least partially surrounds the central region and is disposed between the central region and each of the upper region and the toe region. The intermediate region has a fourth average thickness that is greater than the first average thickness, the second average thickness, and the third average thickness.

Embodiments of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a golf club head may include a body portion with a toe portion, a top portion, a sole portion, and a back portion. The back portion may be include a back wall portion. The golf club head may also include a face portion, an interior cavity, at least one weight portion, and at least one port. The interior cavity may be partially or entirely filled with a polymer material. Other examples and embodiments may be described and claimed.

A golf club head having a multi-layered striking face is disclosed herein. More specifically, the golf club head in accordance with the present invention has an external frontal face layer, an internal rear face layer, and an intermediary sandwiched face layer juxtaposed between the external frontal face layer and the internal rear face layer. The intermediary sandwiched face layer may generally be made out of a high flexural modulus polymeric material.

A composite material golf club head is provided having a body made from a first metal and a face insert press fitted to a portion of the body and made from a second metal The metals are chosen so that the first metal is heavier than the second metal. The second metal is disposed towards the front and top of the body, and is preferably hard-anodized. In addition, an interlocking structure, for example rectangular or dove tail shaped channels, is provided in the body so that the face insert becomes embedded in the interlocking structure to anchor the face insert to the body. Portions of the golf club head, such as the face insert or sole plate, are anodized to protect against corrosion. The anodized coating is colored to improve aesthetic characteristics or infused with a polymer to increase or reduce friction. Disclosed herein is a golf club head having a body portion and a face insert. The front of the body portion further comprises a cutout sized and dimensioned to receive the face insert. The body portion is preferably made from a high-strength metal such as stainless steel, titanium or titanium alloy. The face insert is preferably comprised of a metal having a lower density than that of the body portion. The face insert comprises an aluminum metal matrix composite (MMC) containing an amount of scandium and zirconium. The golf club head may also include a top line insert made of a lightweight material and at least one heavy weight member disposed to the back of the club head.

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 may include a body portion, and an internal mass portion comprising a material having a greater density than a material of the body portion, a height in a top-to-sole direction, a depth in a front-to-back direction, and a width in a toe-to-heel direction. The distance between the internal mass portion and a toe portion edge is substantially less than the distance between the internal mass portion and a heel portion edge. The volume of the internal mass portion increases in a top-to-sole direction, and the height of the internal mass portion is greater than the width of the internal mass portion. Other examples and embodiments may be described and claimed.

A golf club head according to the disclosure is a cavity-back iron type golf club head that includes a face portion and a back portion. The face portion includes a front face and a rear face facing away from each other, the front face being a ball-striking face. A non-metallic member is fixed to the rear face. An abutment portion including a tip portion with a curved surface is provided on the back portion. The abutment portion is passed through the back portion, and the curved surface of the tip portion contacts the non-metallic member.

A golf club head according to the disclosure is a cavity-back iron type golf club head that includes a face portion, a cavity portion provided behind the face portion, and a protrusion provided on a lower part of a rear face of the face portion. The protrusion includes a first recess extending from an upper surface of the protrusion toward a sole, a second recess positioned closer to a toe than the first recess is and extending from the upper surface of the protrusion toward the sole, and a thick portion provided between the first and second recesses in a toe-heel direction. The first and second recesses each has a substantially trapezoidal shape in a cross-sectional view taken along a plane that is parallel to a front face of the face portion and passes through a deepest part of each of the first and second recesses.

An iron-type golf club head with a cavity formed via a multi-stage forging process. The forged iron-type golf club head is formed from a single billet of material. An intermediate step of the multi-stage forging process creates a cavity in the iron-type golf club head which can receive an insert. The resultant iron-type golf club head has a substantially lower center of gravity and higher moment of inertia when compared to a traditionally forged iron-type golf club head lacking a cavity. Additionally, the resultant iron-type golf club head has a more solid feel than a traditionally cast iron-type golf club head as a result of the tighter grain structure the forging process yields.

Embodiments of golf club heads with energy storage characteristics are presented herein. In some embodiments, a golf club head comprises a hollow body comprising a strikeface, a heel region, a toe region opposite the heel region, a sole, a top rail and an inflection point. The inflection point provides increase bending of the strikeface thereby providing performance enhancement over clubs without an inflection point.

The present invention relates to an iron-type golf club head having a hollow body cavity, a hosel with a shaft-receiving bore that communicates with the hollow body cavity to form a continuous cavity structure, and a center of gravity located closer to the toe than to the heel. The iron-type golf club head preferably includes a face component with a striking face and a rear extending sole portion, and may also include supporting ribs within the continuous cavity structure, a hosel cutout covered by a cover made from a lower-density material than that of the hosel, and through-holes extending through a wall of the hosel.
