Abstract
A multiple density golf club head including a heel formed of a dense metallic material, a toe formed of a dense metallic material and a center segment formed of a non-metallic material is provided. The non-metallic material of the center segment has a density substantially less than the metallic material comprising the heel or the toe. The materials in the heel, toe and center segment extend for the entire depth of the club head. The positioning of the higher density regions at the heel and toe of the golf club provides for desirable heel-toe weighting characteristics. Also disclosed is a method for manufacturing a golf club head in accordance with the present invention. The method incorporates various manufacturing techniques into a cost effective process for manufacturing the club head of the present invention.
