Abstract: A golf club head and a method of making the golf club head including bonding tape. The method additionally includes positioning the first piece, the second piece, and the bonding tape, interposed between the first piece and the second piece, in a vacuum bag, and reducing a pressure within the vacuum bag, relative to a pressure external to the vacuum bag, such that the vacuum bag collapses onto the first piece and the second piece and compresses the bonding tape between the first piece and the second piece. The method also includes heating the bonding tape, at least to a curing temperature of the bonding tape, when the pressure within the vacuum bag is reduced.

Abstract: A golf club head that includes a plate opening, a plate-opening recessed ledge defining the plate opening, and a strike plate attached to the plate-opening recessed ledge. The golf club head also comprises a hollow interior cavity. At least a portion of a top half of the plate-opening recessed ledge is made of a first material having a first density and at least a portion of a bottom half of the plate-opening recessed ledge is made of a second material having a second density that is greater than the first density. The top half of the plate-opening recessed ledge is closer to a crown portion of the golf club head than the bottom half of the plate-opening recessed ledge and the bottom half of the plate-opening recessed ledge is closer to a sole portion of the golf club head than the top half of the plate-opening recessed ledge.

Abstract: A method of making a golf club head includes interposing bonding tape between a first piece and a second piece of the golf club head such that the first piece is temporarily adhered to the second piece via a tackiness of the bonding tape. The method additionally includes positioning the first piece, the second piece, and the bonding tape, interposed between the first piece and the second piece, in a vacuum bag, and reducing a pressure within the vacuum bag, relative to a pressure external to the vacuum bag, such that the vacuum bag collapses onto the first piece and the second piece and compresses the bonding tape between the first piece and the second piece. The method also includes heating the bonding tape, at least to a curing temperature of the bonding tape, when the pressure within the vacuum bag is reduced.

Abstract: Disclosed here is a method of making a golf club head. The method comprises steps of laser ablating a second-part surface of a second part of the golf club head such that a second-part ablated surface is formed in the second part, and bonding together a first-part surface, of a first part of the golf club head, and the second-part ablated surface of the second part of the golf club head.

Abstract: A golf club head that includes a first part, a second part, and an adhesive between and bonding together a first-part bonding surface and a second-part ablated bonding surface. The second-part ablated bonding surface includes a second-part ablation pattern of peaks and valleys. The second-part ablation pattern of peaks and valleys includes first paths spaced apart relative to each other, and second paths spaced apart relative to each other and intersecting the first paths at spaced apart locations. Each one of the first paths and the second paths has a depth, relative to the peaks, that varies along its length. The depths of the first paths and the second paths are greater at the spaced apart locations where the first paths and the second paths intersect than where the first paths and the second paths do not intersect.
