Micro Etching Process for Identification

2007

Dear Friends,
We are a Hosur-India based relays & switchgear manufacturing industry. For traceabiity purpose, we need to identify hardened steel cylindrical shaped parts with batch no & date. Moreover, this has to be done at in-house. We feel micro etching is a suitable process. Can anybody throw some light on micro etching & circuit for constructing equipment, etc?
This will be of great help to us.
Thanks & Regards,

Photoetching with sand blast or acid, and laser engraving are some options.
