Golf club heads and methods to manufacture golf club heads
Embodiments of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a golf club head may include a body portion having a first material with a first density, a wall portion extending into the body portion from an inner surface of a bottom portion of the body portion, a weight portion having a second material with a second density different from the first density, a weight port extending into the body portion from the bottom portion between the wall portion and a face portion and configured to receive the weight portion, and a polymer material between the weight port and the wall portion. The height of the polymer material is less than or equal to the weight-port height. Other examples and embodiments may be described and claimed.
