Abstract:
A hollow iron clubhead having a low center of gravity and enabling free selection of a material for the clubface can be readily produced by press working. The hollow iron clubhead mainly comprises a clubface member, a front body member and a rear body member. A blank for forming the clubface member, a blank for forming the front body member and a blank for forming the rear body member are prepared by blanking. The clubface blank and the front body blank are integrally welded together and shaped by hot drawing to form the front body member. The rear body blank is shaped by hot drawing to form the rear body member. The front body member and the rear body member are integrally joined together by welding.
