Electroforming Bath operate at room temperature
Q. My best regards to all plating colleagues. I am using wax as a mandrel material to produce different products from silver electroforming bath which work at room temperature and I am succeeding. Now I want to prepare a gold electroforming bath which will work at temperature less than melting point of wax mandrel, i.e., 35 &C. I would like to be able to electroform to (800-1000) microns; bright finish is not necessary. Can any one help me? What formulas, what are the operating conditions, pH value, and the type of anodes? No problem if the formula is for application of alloy or pure gold plating.
Thanks

A. I know very little about gold electroforming and am not going into details and formulas, but I must inform you the melting temperature of wax is not limited to 35° C. There are several waxes that go up to 50 °C and more. So, don't worry much about operating temperature.

A. Conventional waxes used in electroplating have a melting point of 75-80 °C so electroforming solution does not need to operate at room temperature.
