1. A golf club head comprising:
- a body portion having a toe portion, a heel portion, a top portion, a sole portion, a back portion having at least two ports at or below a horizontal midplane of the body portion, and a front portion having a face portion with a front surface and a back surface;
an interior cavity extending between the top and sole portions and between the face and back portions, at least one of the ports of the at least two ports being connected to the interior cavity;
a bonding portion applied to the back surface of the face portion from the at least one port and bonded to the back surface of the face portion; and
an elastic polymer material injection molded in the interior cavity from the at least one port and to structurally support the face portion during impact with a golf ball,wherein the bonding portion is bonded to the face portion before injection molding the elastic polymer material in the interior cavity,wherein the elastic polymer material is bonded to the bonding portion after being injection molded in the interior cavity,wherein each port of the at least two ports is associated with a port diameter, andwherein a distance between the at least two ports is less than or equal to the port diameter of any of the at least two ports.

9. A golf club head comprising:
-
a plurality of weight portions; a body portion having a toe portion, a heel portion, a top portion, a sole portion, a back portion having at least two ports, and a front portion having a face portion with a front surface and a back surface; an interior cavity extending between the top and sole portions and between the face and back portions, at least one port of the at least two ports being connected to the interior cavity; a bonding portion having an initial cure state and a final cure state with a different bonding configuration than the initial cure state, the bonding portion applied to the back surface of the face portion from the at least one port and configured to bond to the back surface of the face portion at the initial cure state; and an elastic polymer material injection molded in the interior cavity from the at least one port and to structurally support the face portion during impact with a golf ball, the bonding portion configured to bond to the elastic polymer material to the back surface of the face portion at the final cure state, wherein the plurality of weight portions include a greater number of weight portions below a horizontal midplane of the body portion than the number of weight portions above the horizontal midplane of the body portion, wherein each port of the at least two ports is associated with a port diameter, and wherein a distance between the at least two ports is less than or equal to the port diameter of any of the at least two ports. - View Dependent Claims (10, 11, 12, 13)
