Electroforming bath operate at room temperature [Iraq] 

May 2, 2007

My best regards to Mr.Ted mooney and all plating colleagues.I am used wax as mandrel material to produce different products from silver electroforming bath which work at room temperature and i am succeeded.Now i want to prepare agold electroforming bath which operate at room temperature or less than melting point of wax mandrel[60 C].I would like to be able to electroform to [800-1000]microns.Bright finish is not necessary because i am use anegative mandrel in my process and it is simple to finishing.Can anyone helpe me? what formulas ,what the operating conditions,PH value, and type of anodes?.No probleme if the formulas for application of alloy or pure gold plating.

Thanks,

Dear Enad,
I feel it would be better for you depend on supply houses for this process.I know that suppliers have this process which gives as much as 106 mg/amp/minute.

Cyanide gold chemistries are common for electroforming gold alloys and are operated at 55-65oC but lower temperatures can be used adjusting the amperage down correspondingly.

Dear Mohan,
Thank you for participating but you must know that most of the chemical compounds which I need prepared myself from individual chemicals to lower cost, and for the difficulty of importation to Iraq.
