UV Laser Marking Machine

The UV laser marking machine is a high-end cold-process marking device that uses a UV laser. The key factors in choosing a UV laser marking machine are:

Material Type: If you are processing heat-sensitive non-metallic materials (such as plastics, PCBs, and glass) or metal products requiring ultra-fine marking, UV is the preferred choice.

Precision Requirements: If you require extremely high precision and aesthetics in your markings, a UV laser is a must.

Budget Considerations: If a fiber laser can achieve the desired results, provided the process requirements are met, it offers a more cost-effective solution. UV equipment is a solution for specific, high-end needs.

1."Cold Processing" Feature

This is its core advantage. The processing generates virtually no heat, avoiding thermal stress, thermal deformation, slag, and micro cracks in the material, achieving true "cold" marking.

2.Extremely High Processing Precision

The ultraviolet wavelength is extremely short, allowing it to be focused into an ultra-small spot diameter of less than 10 microns, enabling ultra-fine marking that is impossible with fiber and CO2 lasers.

3.Wide Material Compatibility (Particularly for non-metals)

It can process many heat-sensitive materials, a shortcoming of traditional fiber lasers.

4.Excellent Marking Results

Marking edges are crisp and clear, without any burrs or burns. A variety of effects can be produced on the material surface, including shallow and deep engraving, and surface color changes (such as white and gray), with high contrast and excellent aesthetics.

5.Consumables and Maintenance

While there are no consumables, UV lasers typically have a shorter lifespan than fiber lasers (approximately 15,000-20,000 hours), and the water cooling system requires maintenance, resulting in relatively high operating costs.

1. Electronics and Semiconductor Industry (largest application area)

（1）IC Chips: Marking tiny letters and logos on wafers and chips without thermal stress or damage.

（2）FPC/PCB: Marking QR codes and text on flexible printed circuits and PCBs with high precision and without damaging the substrate.

（3）Electronic Components: Fine coding on resistors, capacitors

2. Plastics and Polymer Materials:

（1）Plastic Buttons: Marking characters on mobile phones and remote control buttons with clear and wear-resistant markings.

（2）Medical Devices: Labeling on medical catheters, plastic reagent bottles, and packaging materials with excellent biocompatibility and no chemical contamination.

（3）Food Packaging: Marking production dates and batch numbers on packaging for safety and hygiene.

3. Glass and Ceramics Industry:

（1）Glass: Surface engraving with fine patterns and micro-perforations to achieve a "glass engraving" effect without cracking.

（2）Ceramics: Fine marking on ceramic substrates and electronic ceramic components.

4..Luxury Goods and Cosmetics Packaging:

Ultra-fine logos and patterns on surfaces such as perfume bottles, lipstick tubes, and mobile phone cases enhance product quality.

5.Other Specialty Materials:

Shallow marking of paper packaging, leather, and wood (for special effects rather than depth).
