Designing a plating setup to plate 2" diameter plastic coins

September 21, 2021

Q. Hi, I'm novice to plating and I have a specific project that eventually I would want to do thousands of. It's a 2" diameter 3d printed coin, that I paint in my own graphite and varnish paint mixture. Just a plastic bin, copper, drain cleaner, brightener from a hobby plating supplier, etc. I have good results doing one at a time, would like to do 10 at a time, which is just about the limit of the bench power supply I think.

I've designed and 3d printed a little holder for the coins with a wire running through and touching each coin, but the plating happened mainly on the coins closest to the power supply, so I need a better solution. As you can tell, I have not much of an idea of what I'm doing, and I'm sure there are already solutions for this problem... How can I design a simple electroplating setup to do 10 items at a time evenly? I can 3d print anything needed probably.

Any advice for a novice?
