ABSTRACT:
A highly accurate, efficient, and non-mechanical method of removing material from the surface of a golf club head using the principles of electrolysis. The process generally includes positioning at least one electrode in close proximity to a portion of a rear surface of a striking plate, flowing a liquid containing an electrolyte between the rear surface portion and the electrode, and applying a low voltage between the rear surface portion and the electrode. The electrode has an overall negative charge and the golf club head has an overall positive charge, such that a pulsed high-density DC current passes between the electrode and the rear surface portion. This results in negatively charged electrolytes in the liquid attracting positively charged molecules of the rear surface portion, such that the designated amount of material from the rear surface portion is removed by electro-chemical oxidation and carried away by the liquid flow.
