UV Laser Marking Machine

WDOTMARK T-U5 CCD UV laser marking machine

When fiber lasers are too aggressive for delicate materials, the UV laser marking machine steps in. WDOTMARK's 355nm UV laser systems mark plastics, glass, and coated surfaces with minimal heat — producing crisp, permanent marks where other technologies burn or crack the substrate.

The 355nm Advantage: Cold Marking

UV light at 355nm breaks molecular bonds directly instead of relying on heat. That "cold marking" process keeps the heat-affected zone tiny, which matters for thin-walled plastic parts, glass bottles, and heat-sensitive components. Marks stay sharp, edges stay clean, and the material keeps its original strength and appearance.

WDOTMARK UV Lineup

YT-U5 flying UV — online flying marking for high-speed production lines; marks on the move with no fixturing stops.
U10 portable UV — compact unit for workstation marking of plastic housings, caps, and small parts.
T-U5 CCD UV — vision-positioned marking for precise placement on small or irregular parts.

For metal workpieces that need deep engraving, compare our /fiber-laser-marking-machine/ range. For packaging lines that need date and batch coding rather than permanent marks, see our /industrial-inkjet-printer/ systems.

Where UV Marking Fits

Typical applications include plastic caps and closures, glass bottles and vials, cable and wire marking, and electronic component housings. If your product combines plastic and glass parts on one line, a single UV platform can often cover both — one reason buyers pair UV with our /laser-marking-systems/ selection guide before deciding.

Choosing Your UV Configuration

Power and format depend on your mark size and line speed. The YT-U5 suits continuous online coding; the T-U5 with CCD vision suits precision parts that vary in position. Send us a sample part or a photo of your line — our engineers will recommend the configuration and confirm marking quality with a real test.
