Continuous monitoring of specific gravity during a plating process





2003

Hello:

I am not very knowledgable about the finishing-plating industry but I do have a few simple questions. Are there any particular plating processes where it is important to do a continuous monitoring of the liquid density (specific gravity) during the process? Are there any processes where this would be beneficial?

Thanks for your reply.

It's not very common, George. The S.G. of chrome plating solutions is periodically monitored. Sometimes, as part of an analysis, aluminum content in an etching or anodizing process may be determined with S.G. being one of the inputs. But I'm not aware of any shops which continuously monitor S.G.

SG is used as a primary method of monitoring electropolish solutions (at least some of them) to maintain a proper viscosity due to evaporation of water. I doubt if anyone uses continuous on any metal plating process.
