A method of forming a golf club head includes forming a core of the golf club head from a material having a first melting temperature and affixing a club face to the core. The club face includes a first, hitting surface, a second surface that is opposite the first surface, and a locking feature. A body is then molded about the core and such that it surrounds at least a portion of the locking feature, the body formed from a polymeric material having a second melting temperature that is greater than the first melting temperature. Finally, the core is removed from within the body.
