Key Features and Advantages
Cold Marking Technology
The 355nm UV wavelength creates photochemical rather than thermal reactions, enabling marking of heat-sensitive materials (PET films, thin coatings, flexible PCBs) without melting or deformation. This distinguishes UV systems from conventional fiber or CO₂ lasers.
Vision-Assisted Automation
Integrated CCD cameras provide:
Automatic workpiece recognition
Barcode/QR code reading for traceability
Real-time mark quality inspection
Coordinate system correction for irregular surfaces
High-Contrast Marking
UV lasers induce molecular structure changes in materials, producing marks with:
90%+ contrast ratio on most plastics
No material removal (clean process)
Chemical resistance superior to inkjet
Precision Motion System
Linear motor stages with 0.1μm resolution
Dynamic focus adjustment
Rotary axis integration for cylindrical parts
Vibration isolation mechanisms
