Why are more and more manufacturers selecting 355nm UV laser marking 

The growing need for product traceability and branding drives more and more manufacturers to integrate product coding and marking systems into their production environment. UV lasers have become progressively more affordable and inexpensive to operate (because of low maintenance requirement and no need for consumables). The systems are capable of high-speed marking of many substrates and are ready to use with a quick and simple set-up.
