Golf club heads and methods to manufacture golf club heads
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 may include a body portion with an interior cavity and a port having an opening to the interior cavity. A polymer material is injected into the interior cavity from the port. The golf club head may further include a first mass portion and a second mass portion. The first mass portion may have a first end, a second end, and a first mass portion distance between the first end and the second end. The second mass portion may be coupled to the back wall portion below a horizontal midplane of the body portion. The second mass portion may include a first end, a second end, and a second mass portion distance between the first end and the second end. The total mass of the second mass portion may be greater than a total mass of the first mass portion, and the second mass portion distance may be greater than the first mass portion distance. Other examples and embodiments may be described and claimed.
