Main Features
1. High precision
The focused spot of UV laser is very small, so it can realize high precision marking and engraving.
2. Low thermal effect
Compared with infrared laser, UV laser has a small heat-affected zone, which does not cause thermal effect and material combustion, and the thermal effect on the processed material is negligible.
3. Wide applicability
It can be applied to a wide range of materials, such as plastic, glass, rubber, ceramics, paper, etc. It is especially suitable for ultra-fine marking and engraving.
4. Environmentally friendly and non-polluting
It does not require the use of ink and other consumables during operation, so it will not cause any environmental pollution problems.
5. Easy to operate
It is flexible in installation, easy to operate, and its modular design is easy to install and maintain.
Application Fields
1. Electronic industry
It can be used for marking and engraving of electronic components, integrated circuits, printed circuit boards (PCB) and other products.
2. Medical device industry
It can be permanently marked on surgical tools, medical packaging and other products to improve the safety and accuracy of medical operations.
3. Food and pharmaceutical packaging industry
Non-contact marking can be realized to ensure that the information is clear and permanent and not easy to erase, to meet the requirements of food safety and traceability.
4. Glass and Ceramic Products Industry
High precision marking and engraving on glass and ceramic surfaces to meet the demand for personalized customization.
5. Polymer materials industry
High-contrast marking can be performed on PVC, ABS and other plastic materials widely used in consumer electronic products, automotive parts and so on.

Frequently Asked Questions
What is the working principle of the UV laser marking machine?
The UV laser marking machine works by using high energy photons to break the chemical bonds within the material or surrounding medium. This non-thermal process, called "cold processing" or "photo-etching", avoids heating or thermal deformation on the inner and surrounding layers, allowing for ultra-fine marking.
What materials can the UV laser marking machine be applied to?
It is suitable for a wide range of materials, including plastics (such as PVC and ABS), glass, rubber, ceramics, paper, polymer materials, and metal surface plating. It is especially ideal for ultra-fine marking requirements.
Why is UV laser marking considered environmentally friendly?
During operation, the UV laser marking machine does not require the use of ink or other chemical consumables. This clean process eliminates chemical waste and prevents environmental pollution issues.
What is the expected lifespan of the laser module?
The laser module has a service life of up to 20,000 hours. It is supported by a durable industrial water-cooling mechanism that keeps the laser running stably for long periods.
What industries benefit most from UV laser marking?
Key industries include the electronics industry (PCBs and integrated circuits), medical devices (surgical tools and medical packaging), food and pharmaceutical packaging (traceability information), glass and ceramics, and polymer materials used in automotive and consumer electronics.
