Parts are good, Hull-cell Panels are bad
Hello......
A Hull-Cell test results are every time %100 right for nickel plating?After I run Hull-Cell test panel,when I excamine it, I see hazy and gray areas.But When I see our parts which plated nickel, normal and any defects?How can we explain this situation? This event depend on part's geometrical shape? Thanks........ Sincerely......

As someone who has been looking at my and my clients hull cell panels for over thirty years I first need to ask if you are running panels that are representative of your operating conditions. By this I mean temperature, agitation, current density, etc. Also don't forget that the panel needs to be clean or you can get streaking and blotching that are not related to the plating bath. Finally, if all the above are correct, use a Hull Cell ruler and look at the area of the panel which represents the current range you operate in, sometimes this is OK when the defects are in parts of the panel outside your normal plating parameters and will not effect your plating.
The test cell is a guide and a diagnostic tool, it is not an end in itself. At the end of the day you plate parts not panels!
