Abstract
A golf club head having a defined internal cavity, and a golf club head containing a bi-material weight having a nonhomogeneous structure is disclosed herein. A method to add the bi-material weight to the golf club entails heating, vibration and cooling to produce the nonhomogeneous structure is also disclosed herein.
Claims16
A method of producing a golf club head with a specific weight, the golf club head having an internal cavity defined by a plurality of walls of the golf club head, the internal cavity having an opening for access thereto, the method comprising:
- placing a plurality of tungsten spheres within the internal cavity;
- dispensing a second weight material into the internal cavity, the second weight material heated to a liquid phase, the second weight material having a density that is lower than tungsten;
- imparting vibrational energy to orient the plurality of tungsten spheres throughout the second weight material within the internal cavity;
- and
- cooling the second weight material to a solid phase within the internal cavity.
A method of producing a golf club head with a specific weight, the golf club head having an internal cavity defined by a plurality of walls of the golf club head and having an opening for access thereto, the method comprising:
- placing a first weight material into the internal cavity through the opening, the first weight material having a density ranging from 12 g/cm3 to 20 g/cm3;
- dispensing a second weight material into the internal cavity through the opening, the second weight material heated to a liquid phase, the second weight material having a density that is less than the density of the first weight material;
- imparting vibrational energy to the golf club head to provide intimate contact between the first weight material which forms a discontinuous phase and the second weight material which forms a continuous phase;
- and
- cooling the second weight material to a solid phase within the internal cavity.
A method of producing a golf club head with a specific weight, the golf club head having an internal cavity defined by a plurality of walls of the golf club head, the internal cavity having an opening for access thereto, the method comprising:
- placing a plurality of tungsten alloy spheres within the internal cavity;
- dispensing a bismuth-tin solder into the internal cavity, the bismuth-tin solder heated to a liquid phase;
- imparting vibrational energy to orient the plurality of tungsten alloy spheres throughout the bismuth-tin solder within the internal cavity;
- and cooling the bismuth-tin solder to a solid phase within the internal cavity.
