This UV Laser Metal Marking Machine offers dual power options (5W/10W) with a 355nm cold laser source—generating minimal heat input to avoid metal discoloration or structural damage. The 5W model uses a compact air-cooling system (weight: 12kg) ideal for delicate work like jewelry engraving, while the 10W version adopts a closed-loop water cooling system (temperature control accuracy ±0.5℃) for deeper marking on stainless steel, aluminum, and titanium alloys. Its high-precision linear guide rail and servo motor system ensure ±0.001mm repeat accuracy, meeting strict aerospace component marking demands (e.g., turbine blade serial numbers).

The global UV laser marking market for metals hit $1.2B in 2024, with jewelry (28% share), automotive parts (24%), and medical devices (21%) driving growth. In the luxury jewelry sector, 83% of manufacturers prefer UV laser technology for its ability to create intricate patterns (e.g., micro-engraved gemstone settings) without damaging metal surfaces—compared to traditional mechanical engraving, which has a 15% rejection rate. The automotive industry’s shift to lightweight aluminum components has boosted demand for UV marking, as it avoids heat-induced material weakening.
Cold Marking Technology: Thermal impact zone <0.01mm, preserving metal integrity—critical for medical implants (e.g., titanium bone screws) and aerospace parts
Power Versatility: 5W model excels at fine inscriptions (0.008mm line width) on 18K gold jewelry; 10W version achieves 0.5mm deep engraving on stainless steel in 40% less time than 5W (15 seconds vs. 25 seconds per mark)
Broad Compatibility: Marks plated metals (chrome, nickel), high-strength alloys (Inconel), and even gemstone-embedded jewelry (e.g., diamond-studded rings) without damaging stones
Rapid Processing: 12,000mm/s marking speed with 0.012mm minimum line width; supports continuous marking of 500 small metal parts (e.g., watch gears) per hour
Meets FDA laser safety standards (21 CFR Part 1040.10, Class IV) and RoHS environmental requirements (restricting lead, cadmium, and mercury content <1000ppm). The laser source maintains 95% power stability over 10,000 operating hours, and the water cooling system in the 10W model has a 5-year leak-proof guarantee. Under ISO 10110 testing, marking contrast remains >80% after 500 hours of salt spray exposure.
Adjustable focus height (50-200mm) for irregular metal workpieces like curved automotive trim or asymmetrical jewelry
Automated feeding system integration (conveyor belt + sensor) for mass production of small parts (e.g., electronic connectors)
Custom wavelength tuning (350-360nm) for specific metal alloys (e.g., Hastelloy for oilfield equipment)
Medical-grade sterilization-compatible machine casings for use in cleanrooms.
