5W UV Laser Marking Machine

The UV laser marking machine is part of the laser marking machine series, so its working principle is largely similar to that of general laser marking machines-both use laser beams to create permanent marks on the surfaces of various materials. The marking effect is achieved by short-wavelength lasers directly breaking the molecular chains of materials, thereby revealing the desired etched patterns and text.

Key Features

• Due to the extremely small focused spot size and minimal heat-affected zone (HAZ) of UV lasers, UV laser marking machines can perform ultra-fine marking and mark special materials. They are the preferred choice for customers with higher requirements for marking quality.
• Except for copper materials, UV lasers are compatible with a much wider range of materials.
• They not only feature excellent beam quality and smaller focused spots, enabling ultra-fine marking;
• They also have a broader application scope;
• The heat-affected zone is extremely small, avoiding thermal effects and material burning issues;
• They offer fast marking speed and high efficiency;
• They boast stable overall performance, compact size, and low power consumption.

Applications

With its unique low-power laser beam, the UV laser marking machine is particularly suitable for high-end markets requiring ultra-fine processing. Its applications include:

• Marking on the surfaces of packaging bottles for cosmetics, pharmaceuticals, food, and other polymer materials-delivering fine, clear, and durable marks that outperform inkjet printing and are pollution-free;
• Marking and dicing of flexible PCB boards;
• Processing of microholes and blind holes on silicon wafers;
• QR code marking on LCD glass, surface drilling of glassware, marking on metal surface coatings;
• Marking on plastic buttons, electronic components, gifts, communication equipment, and building materials.
