    摘要: A golf club head (22) composed of an interior body (42) having a first density and an outer shell (40) having a second density is disclosed herein. The golf club head (22) is preferably a putter. A method (100) for forming the golf club head (22) is also disclosed herein. The interior body (42) is preferably composed of an injectable polyurethane material integrated with tungsten to have a density between 4.0 g/cc to 10 g/cc. The outer shell (40) is preferably composed of a thermoplastic material such as an ionomer blend to have a density less than 1.0 g/cc.
