Lasermarking on 416 Stainless steel





September 10, 2010

Hello, I use a VersaLaser VL200 with an HPDFO head, for small and finite laser marking on 416 stainless medical tools.

I wanted to know if anyone has laser marked unpainted, unpolished stainless and has some tips or chemicals that they use to best clean the surface in preparation.

Right now I use a commercial solvent (Purple Power), methanol, then acetone. I clean my parts in a sonic cleaner with each one of the aforementioned chemicals, one chemical at a time of course. Any critiques on my cleaning process? Suggestions?

Update:

I now boil my pieces in a solution of Alconox and water, then sonic-clean in methanol and sonic-clean in acetone. This seems to work better, but with all of the harsher sterilization procedure on the forefront, are there better ways to go about this lasermarking preparatory procedure?
