UV Laser Marking Machine
Cold marking — ultra-fine, heat-free marks on plastics, glass, PCB and medical or food packaging.
Overview
UV — 355 nm
A 355 nm UV source breaks molecular bonds instead of heating the surface, so there is no melt, burn or heat-affected zone. That makes UV the choice for white and clear plastics, glass, silicon, ceramics, FR4 and anything regulated — pharma, food and medical.
What it does
Dedicated work this machine performs.
No thermal damage on thin films, cables, catheters and soft plastics.
Sub-50 µm characters and 2D codes on PCBs and electronics.
Crack-free, high-contrast codes on ampoules, vials and tiles.
High contrast where fiber cannot mark at all.
Logo and lot on capsules, blister packs and pouches.

FAQ
Common questions
Why UV instead of fiber for plastics?
Fiber heats the surface and can foam or discolour white/clear plastics. UV marks cold, so the surface stays smooth and food/medical-safe.
Is 3 W enough?
For most plastic and glass marking, yes. 5–10 W for faster lines or deeper contrast on ceramics.
Does it mark metals?
Lightly — for metals choose fiber. UV is for non-metals and precision.
