Golf club head and method for making the same

A method for making a golf club head, comprising the steps of:

• A) forming a club head main body which has at least one internal cavity in spatial communication with an external space through at least one opening of the club head main body;
• B) simultaneously or separately introducing a plurality of metallic particles and a binding material into the at least one internal cavity through the at least one opening;
• and
• C) curing the binding material inside the at least one internal cavity to form a cured binding material so that the plurality of metallic particles are bonded to one another through the cured binding material to form at least one counterweight block, the at least one counterweight block having a cross-section dimension that is greater than a cross-section dimension of the at least one opening.
