Mini Water Cooling UV laser marking machine
(3W 5W 7W 10W 15W 20W Optional)

The mini water-cooled UV laser marking machine is a compact, high-precision "cold processing" device that uses a 355nm ultraviolet laser. It integrates a mini water chiller for stable heat dissipation, making it ideal for fine marking on heat-sensitive materials in limited spaces.

It is widely used in marking and slicing of flexible PCB, silicon wafer micro-hole , blind hole processing, LCD glass QR code, glassware surface punching, metal surface coating, plastic keys, electronic components, gifts, communication equipment, construction materials ,rubber and other non-metallic materials.

1.Mini & Portable Design
Split/desktop integrated structure (main unit + small water chiller, total weight ＜50kg). It fits a 60×60cm workbench, easy to move and install—no complex commissioning required.

2.Cold Processing, Zero Thermal Damage
The 355nm UV laser features ultra-low heat affect zone (＜0.1mm). It avoids burning, deformation or edge burrs on plastics, glass, films and PCBs—perfect for fragile/high-precision parts.

3.Ultra-High Precision & Durability
Focus spot as small as 0.01mm, supporting micro-text (0.3mm height), QR codes and intricate logos.
Permanent marking: resists fading from friction, acid/alkali or extreme temperatures.
Water cooling ensures 24/7 stable operation (power stability ＜±3% over 24h).

4. Wide Material Compatibility

1. Glass and crystal products, automobile glass, arts and crafts, ceramic cutting or engraving, watches and glasses.
2. Electronic components, PCB circuit boards, chips, chargers, wires, computer accessories keyboards, plastic buttons, mobile phone accessories (mobile phone screens, LCD screens), etc.
3. Cosmetics, pharmaceuticals, food and other packaging materials for marking and microporous drilling.
4. Hardware machinery, tools, measuring tools, knives, bathroom faucets, instruments, optical devices, aerospace, military supplies
