Electroforming Bath operate at room temperature  

January 24, 2009

My best regards to all plating collegues. 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 woud like to be able to electroform to (800-1000)microns; bright finish is not necessary. Can any one help me ? What formulas, what the operating conditions pH value, and the type of anodes? No probleme if the formulas is for application of alloy or pure gold plating.
Thanks

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 35oC. There are several waxes that go up to 50oC and more. So, don´t worry much about operating temperature.

Conventional waxes used in electroplating have a metting point of 75-80C so electroforming solution do not need to operate at room temperature
