3 W UV Laser Coder
Entry UV coder for plastics, films and labels at moderate speeds.

Built around your product
The UV-3 brings cold marking to lines that code white HDPE bottles, pharmaceutical cartons, cosmetic tubes and flexible film. It produces dark, high-contrast codes without additives and without piercing barrier layers.
An infrared beam is frequency-tripled inside the laser cavity to produce ultraviolet light, then delivered through a galvo scan head. The small spot size gives very fine characters and dense 2D codes. Because the heat-affected zone is minimal, UV is the usual choice for white HDPE, flexible film, medical tubing, cable jackets, glass and chip packages.
Key features
- Photochemical mark with minimal heat
- High contrast on white HDPE and PP
- Compact scan head with integrated focus pointer
- Touchscreen controller with user levels
Process sequence
Position
Product is presented on the conveyor, in a tray or on a fixture.
Focus
A fixed or motorised Z-axis sets the focal distance for the part height.
Mark
The 355 nm beam changes the surface colour without cutting into it.
Extract
Light fume extraction keeps the lens and product clean.
Inspect
An optional vision system grades the code before the part moves on.
