Golf club heads and methods to manufacture golf club heads

Abstract

Embodiments of golf club heads, golf clubs, and methods to manufacture golf club heads and golf clubs are generally described herein. In one example, a golf club head includes a hollow body portion comprising an interior portion and an exterior portion, a first mass portion, a second mass portion coupled to the interior portion of the body portion, and a port extending from the exterior portion of the body portion to the interior portion of the body portion, the port being at a different location on the body portion than the first mass portion and the second mass portion. A maximum width of the interior portion of the body portion is below a horizontal midplane of the body portion and between the first mass portion and the second mass portion. Other examples and embodiments may be described and claimed.

         3 . A golf club head as defined in  claim 1 , wherein the filler material comprises a first polymer material having a first elasticity and a second polymer material having a second elasticity different from the first elasticity. 
     
     
         4 . A golf club head as defined in  claim 1 , wherein the second mass portion comprises a top portion and a bottom portion oriented relative to each other at a non-zero angle. 
     
     
         5 . A golf club head as defined in  claim 1 , wherein more than 50% of a total mass of the second mass portion is below a horizontal midplane. 
     
     
         6 . A golf club head as defined in  claim 1 , wherein the second mass portion is configured to at least partially correspond to a shape of a portion of the toe portion edge that is proximate to the second mass portion. 
     
     
         7 . A golf club head comprising:
 a hollow body portion defining an interior cavity, the hollow body portion comprising:
 a material having a body material density; 
 a toe portion with a toe portion edge; 
 a heel portion with a heel portion edge; 
 a front portion including a face portion; 
 a back portion with a back wall portion; 
 a top portion with a top portion edge; 
 a body mass portion extending from the back wall portion toward the front portion and extending from the toe portion edge toward the heel portion, the body mass portion having a front side being spaced apart from the face portion; 
 an external port connected to the interior cavity; and 
 an internal port defined by a recess on the front side of the body mass portion, the internal port located proximate to the toe portion edge and having a shape that at least partially corresponds to a shape of a portion of the toe portion edge; 
   a filler material in the interior cavity, the filler material having a greater elasticity than a material of the hollow body portion;   a first mass portion coupled to the hollow body portion, the first mass portion comprising a material having a first density different from the body material density, and   a second mass portion having a shape corresponding to the shape of the internal port, the second mass portion comprising a second material having a second density different from the body material density,   wherein the internal port is configured to receive the second mass portion, and   wherein a maximum width of the interior cavity is below a horizontal midplane of the hollow body portion and between the first mass portion and the body mass portion.   
     
     
         8 . A golf club head as defined in  claim 7 , wherein the external port is configured to receive the first mass portion to close the external port. 
     
     
         9 . A golf club head as defined in  claim 7 , wherein the second mass portion has a different shape than the first mass portion. 
     
     
         10 . A golf club head as defined in  claim 7 , wherein the body mass portion is a continuous one-piece part of the hollow body portion. 
     
     
         11 . A golf club head as defined in  claim 7 , wherein at least a portion of the first mass portion is below the horizontal midplane of the hollow body portion. 
     
     
         12 . A golf club head as defined in  claim 7 , wherein the hollow body portion comprises another external port connected to the interior cavity. 
     
     
         13 . A golf club head as defined in  claim 7 , wherein more than 50% of a total volume of the second mass portion is below the horizontal midplane. 
     
     
         14 . A golf club comprising:
 a shaft having a first end and a second end;   a grip coupled to the first end;   a golf club head comprising:
 a body portion having a hollow interior portion and an exterior portion, the body portion comprising a toe portion with a toe portion edge, a heel portion with a heel portion edge, a front portion including a face portion, a back portion with a back wall portion, a top portion with a top portion edge, a sole portion with a sole portion edge, and an interior port defined by a recess in the hollow interior portion; 
 a first mass portion coupled to the body portion below a horizontal midplane of the body portion, and 
 a second mass portion coupled to the body portion in the interior port; 
 wherein the second mass portion increases in mass in a top-to-sole direction, and 
 wherein a maximum width of the hollow interior portion of the body portion is below the horizontal midplane and between the first mass portion and the second mass portion. 
   
     
     
         15 . A golf club as defined in  claim 14 , wherein the hollow interior portion of the body portion is at least partially filled with a filler material. 
     
     
         16 . A golf club as defined in  claim 14 , wherein the second mass portion comprises a top portion and a bottom portion oriented relative to each other at a non-zero angle.
