Cyanide Copper Strike
Our plating facility uses a copper cyanide strike in the process for plating zinc diecasts. Can the cyanide strike be eliminated and if so with what type of a plating bath?
Q: Our plating facility uses a copper cyanide strike in the process for plating zinc diecasts. Can the cyanide strike be eliminated and if so with what type of a plating
bath? B.B.
A: The copper cyanide strike bath that you are currently using can be replaced with an alkaline non-cyanide copper strike. All of these products are proprietary. There are a number of companies that market this type of plating bath. You can find vendors by going to www.pfonline.com and doing a search in the Supplier/Vendor database under Copper Plating Processes. Be aware that these proprietary processes typically require a little more attention than the classic cyanide based bath.
