ABSTRACT:
A one-piece, hollow, moulded head for a golf-club of the "wood" or "driver" type is made by injecting a thermoplastics material around a fusible core having a melting-point below the injection temperature, allowing the injected material to set and melting out the core.
One or more holes are provided, the holes extending completely through the core, so that the injected material fills each hole and sets therein to provide corresponding internal "struts" in the moulding.
The injected material may be, e.g., a polyamide, a polycarbonate, a poly(phenylene oxide), an acetal resin or an ABS resin. The material may be reinforced with up to 50% by weight of glass and/or carbon fibres.
The moulded head may optionally be filled with a polyurethane foam.
The finished moulding may have the conventional face-pieces and/or sole-plates attached thereto.
