Hi!
Does anybody know if is there a mechanical method to mark sheet metal parts for industrial and traceability purposes?
We tried to use a simple stamping tool + hammer that made a letter mark but after painting it was not visible anymore.
Is there a hand machine able to do this?
Could be any shape: letter, digit, dot, dash.
It must be visible after painting, nothing more.

Thank you in advance for any opinion!

Yes there is needle marking equipment available that does this but it depends of how thick coating you will apply

I use an automatic center punch alot for layout. Sterret makes a nice one, but I purchased one from HF and it works good too. Here is a link to the HF punch http://www.harborfreight.com/spring-loaded-center-punch-621.html
The tip also works good as a scribe.

70-100 microns powder coating.
Sometimes more after repainting.

Doesn't help.
I need to know who produced the parts.
