3-D printed plating barrel used to create the rose/copper colored brass cases. Barrel is partially submerged in electrolytic solution with parts inside. “Danglers” are electrified to plate copper onto the parts.

We are still perfecting the final shine and finish, but we think we have a promising option using the plating barrel as a scalable choice to add color to brass cases.

I am really excited about this! I can’t wait to see how far you guys can take this. Hooyah
We are too. We’ll keep you posted. Thanks for your support.
I have to say guys, I wasn’t to interested until I seen the copper plate results. It’s AWESOME. The rose color gives the rounds a very clean look. Again awesome. Hope this works out for you.
Thanks William! We sure do like it.
