A golf club with a multi-material face is disclosed herein. More specifically, the golf club head in accordance with the present invention has a multi-material striking face portion that is made out of a backing layer having a frontal pocket, made out of titanium, and an insert, made out of a composite material, adapted to be inserted into the frontal pocket. The frontal pocket and the insert could have complementary dovetail shaped undercut features to create a mechanical bond between these two components.

Golf club head having a multi-material face and method of manufacture

Golf club head having multi-material face and method of manufacture

A golf club head having a laser-generated features to create contrast on the club face of the golf club head. The club face includes a central region, a toe region, and a heel region. The central region includes a first plurality of laser-generated features that provide a height-intersection coverage of the central region, a width-intersection coverage of the central region, and a surface-area coverage of the central region. The laser-generated features increase the surface roughness value of the external surface of the club face by imparting micro-grooves that have an average groove depths of between about 45 μm and about 60 μm.

Laser contrasted golf club head and manufacturing process

A golf club head with a crown comprising an inner crown portion and an outer crown portion. The inner crown portion may be made of a low density or low elastic modulus material. The outer portion of the crown defines an opening to the cavity. The inner portion of the crown is attached to the outer portion of the crown such that the opening is covered by the inner portion of the crown.

Golf club having a low modulus crown

A multi-material iron type golf club head is disclosed. More specifically, the golf club head may have a first metallic portion, a second metallic portion, and a lightweight portion. The first metallic portion and the second metallic portion collectively define all external surfaces of the golf club head. The lightweight portion may be located within an interior cavity of the golf club head and may contact and support the striking face, the topline portion, the rear wall portion, and the sole portion of the golf club head.

Hollow co-molded iron with inner lightweight portion

A golf club with a multi-material face is disclosed herein. More specifically, the golf club head in accordance with the present invention has a striking face portion that is backed by a composite layer. The multi-material face disclosed in accordance with the present invention may generally be manufactured via a bladder molding process that applies hydrostatic forces to the composite layer to create a more consistent bond between the composite material and the metallic material.

A small-format metal wood golf club head may include a first portion including at least a striking face formed of an alloy of titanium and a second portion including at least a portion of a sole formed of an alloy of steel. The golf club head exhibits beneficial characteristics of both titanium and steel in that the titanium striking face is lighter than a steel striking face having the same coefficient of restitution (COR) and the steel sole allows for concentration of mass in a beneficial location within the golf club head, while overcoming traditional difficulties in bonding titanium and steel.

Multi-material golf club head

A golf club head with a crown comprising an inner crown portion and an outer crown portion. The inner crown portion may be made of a low density or low elastic modulus material. The outer portion of the crown defines an opening to the cavity, a riser extending into the cavity, and a ledge extending from the edge of the riser. The ledge may define a first channel and a second channel that extend around the ledge. The first channel is filled with adhesive to secure the inner portion of the crown to the ledge. The inner portion of the crown is attached to the ledge such that the opening is covered by the inner portion of the crown. The golf club head may also have a sole comprising an inner sole portion and an outer sole portion.
