Abstract: A golf club head with at least one cavity including a weight that is co-molded with a fill material comprising a polymer and a plurality of microscopic bubbles, and methods of manufacturing such golf club heads, are disclosed herein. The plurality of microscopic bubbles constitutes at 5-70% of the volume of the fill material, and more preferably approximately 20-30% of the volume of the fill material. The polymer material preferably is a polyurethane having a Poisson's ratio of 0.40-0.50. The weight is preferably composed of a metal alloy with a density greater than 4 g/cc, such as steel or tungsten alloy.

Abstract: The present invention relates to an iron-type golf club head having a lightweight hosel and a high, toe-ward located center of gravity. The golf club head preferably includes a hollow body with a hosel and an interior mold line that extends into the hosel and is separated from a shaft bore by a solid barrier that does not include any through-holes. An upper portion of the body may include a pocket to hold a high-density weight, and the hosel wall may include multiple through-bores to further lighten the hosel. The golf club head may also include one or more internal ribs extending from the hollow interior of the body into the interior of the hosel.
