ZINC ELECTROPLATING ON ID OF TUBULAR COMPONENTS
(OP)
Dears
We have a product of size 320mm long and ID 80mm , which requires to be zinc electroplated as per ASTM B633 TYP 3.But at the time of electroplating we observed that the ID portions are not getting zinc depositions and hence parts are getting rejected on coating.Can anyone pls advise how we can process zinc plating on ID area.We are doing plating by hanging the parts in the bath(vat plating) with air supplied into the bath to ensure flow.

You may have to hang a round zinc bar in the center of each tube, and connect those bars as the counter-electrodes.
