A UV laser marking machine uses an ultraviolet laser beam (usually 355 nm
wavelength) to create very fine, high-precision marks on materials. It is called a
“cold laser” because it produces very little heat, so it does not damage delicate
materials.
1. How a UV Laser Marking Machine Works
• The machine generates a UV laser beam (355 nm).
• The beam is focused through a galvo scanning system.
• The laser changes the chemical structure of the material surface.
• This creates permanent marks, text, logos, QR codes, or designs.
Because the heat affected zone is very small, the marking is very clean and precise.
