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 body portion, a face portion, a port connected to an interior cavity of the body portion, a filler material in the interior cavity, and first and second mass portions coupled to the body portion. The first mass portion is cylindrical. Each of the first and second mass portions includes a material having a different density than the body portion density. A distance from the second mass portion to a toe portion edge of the body portion is less than a distance from the first mass portion to the toe portion edge. The mass of the second mass portion varies in a top-to-sole direction. Other examples and embodiments may be described and claimed.

 a first ledge portion extending from a location at or proximate to the toe portion edge toward the heel portion edge; 
 a second ledge portion extending from the first ledge portion toward the heel portion edge; and 
 a third ledge portion extending from a location at or proximate to the heel portion edge to the second ledge portion; 
   a face portion coupled to the body portion at the front portion;   a filler material in an interior cavity;   an external mass portion comprising a material having a greater density than a material of the body portion; and   an internal mass portion comprising a material having a different density than a material of the body portion;   wherein the external mass portion and the internal mass portion have different shapes, and   wherein the second ledge portion at least partially surrounds the external mass portion.   
     
     
         9 . A golf club head as defined in  claim 8 , wherein the first ledge portion and the second ledge portion are sloped relative to the sole portion edge. 
     
     
         10 . A golf club head as defined in  claim 8 , wherein a maximum width of the interior cavity is between the external mass portion and the internal mass portion. 
     
     
         11 . A golf club head as defined in  claim 8  further comprising a port on the body portion connected to the interior cavity, wherein the port is between the external mass portion and the internal mass portion. 
     
     
         12 . A golf club head as defined in  claim 8  further comprising a port on the body portion connected to the interior cavity, wherein the port is configured to receive the external mass portion. 
     
     
         13 . A golf club head as defined in  claim 8 , wherein a shape of the internal mass portion is configured to at least partially correspond to a shape of a portion of the toe portion edge. 
     
     
         14 . A golf club head as defined in  claim 8 , wherein the external mass portion defines a visible portion of a center portion of the back wall portion at or below a horizontal midplane of the body portion.
