Golf putter and method for manufacturing the golf putter
View Patent ↗A golf putter includes a shalt and a head secured to the shalt. The head includes a forward portion that defines a face, and the head includes a rear portion positioned rearward of the face. The rear portion may have the configuration of a ring structure. Whereas the forward portion is formed of a first material, the rear portion may be formed of a different material with greater density. In manufacturing the head, the rear portion may be formed and then placed within a mold having the shape of the entire head. Molten first material is then introduced into the mold to form the forward portion.
1. A method of manufacturing a golf club having a bead and a shaft secured to the head, the method comprising steps of:
casting a rear portion of the head with a molten steel material, the rear portion being cast to define an aperture that extends from an upper surface to a lower surface of the head;
placing the rear portion into a mold having a void with a shape of the head; and
molding a forward portion of the head by introducing a molten aluminum material into the mold and adjacent the rear portion.
2. The method recited in claim 1 , wherein the step of casting further includes defining a protrusion that extends into the aperture.
3. The method recited in claim 1 , further including a step of positioning a plate adjacent the roar portion to limit flow of the molten aluminum material.
4. The method recited in claim 3 , wherein the step of casting includes defining cavities in the rear portion.
5. The method recited in claim 4 , wherein the step of positioning includes locating the plate adjacent the cavities.
6. A method of manufacturing a golf club having a head and a shaft, the method comprising steps of:
casting a rear portion of the head from a molten steel material, the rear portion being cast to define:
an aperture that extends from an upper surface to a lower surface of the head,
a protrusion that extends into the aperture, and
at least one cavity;
positioning a plate adjacent the at least one cavity;
placing the rear portion and the plate into a mold having a void with a shape of the head; and
molding a forward portion of the head by introducing a molten aluminum material into the mold and adjacent the rear portion.
7. The method recited in claim 6 , further including a step of securing the head to the shaft.
8. A method of manufacturing a golf club having a head and a shalt secured to the head, the method comprising steps of:
forming a rear portion of the head from a first material, the rear portion having an aperture tat extends from an upper surface to a lower surface of the head,
placing the rear portion into a mold having a void with a shape of the head; and
molding a forward portion of the head by introducing a second material into the mold and adjacent the rear portion.
9. The method recited in claim 8 , wherein the step of forming further includes defining a protrusion that extends into the aperture.
10. The method recited in claim 8 , further including a step of positioning a plate adjacent the rear portion to limit flow of the molten aluminum material.
11. The method recited in claim 10 , wherein the step of forming includes defining at least one cavity in the rear portion.
12. The method recited in claim 11 , wherein the step of positioning includes locating the plate adjacent the cavity.
13. The method recited in claim 8 , wherein the step of forming includes casting the rear portion.
14. The method recited in claim 8 , further including a step of selecting the first material to be steel and the second material to be aluminum.
