Making rree-standing gold foils by electroplating


(1999)

Is it feasible to make free-standing gold foils of 2 to 7 micron (0.0001 to 0.0003") thickness using electroplating or PVD? Any supplier? What would be the cost of a 6" dia foil?

Actually, they call it electroforming when you're making a part by electroplating processes. You make a mandrel out of wax, aluminum, or passivated stainless steel and start plating. The well known "Plater B", Berl Stein, is an electroforming expert who usually does prototype work in nickel or cobalt at NiCoForm, Inc. [Rochester, NY] but he may be able to help.

The cost of precious metals is the driving force in their cost. Look up the daily cost of gold, add maybe 50 - 100 percent for the losses in making gold solution from gold, and the losses in making gold from gold solution, plus labor and machine depreciation for a rough cost until you can get quotes.
