Laser Engraving on Medical Grade Silicon Leaving Tough Residue
Laser Engraving on Medical Grade Silicon Leaving Tough Residue
(OP)
We are using an Epilog laser to engrave on rubber, but the laser is leaving behind a residue in the engraving that is extremely difficult and to remove. We are currently using rubbing alcohol with a Q-Tip to remove the residue by hand and this requires several deep cleanings to get a sub-par result. This is very time-consuming and will completely bottle-neck our process once we are mass producing these items. Are there any suggestions on a better cleaner to use, or a better rubber material which won't stain? The rubber does not need to be medical grade, it just needs to flex and be comfortable on skin.

What I don't understand is why you want to remove a naturally adherent, no-cost visual filler that provides such strong contrast, greatly improving readability.
I really, really hate having to fiddle with lateral illumination in order to read product markings that are molded or embossed too small and/or too shallow to cast a deep shadow.
