Dull plating on ABS

We do Cu-Ni-Cr plating on ABS plastic but recently facing a dullness (mostly at LCD) on finished goods. We tried out with increasing & decreasing current densities but no result, we also done the excess addition of brighteners but the issue is same. So suggest the solution.

Hello, Manish. Have you run Hull cell panels and, if so, what results are you getting? Please don't tell us you add and remove brighteners from a production tank without trying things in a 267 ml sample first :-)
