UV marking machine
UV Laser Marking Machine | Cold Laser Marker
Model: CZ-UVL10/20/308-A, CZ-UVL10/20/303-B
Power: 5W / 10W / 15W
Perfect for ultra-fine marking on plastic, glass, ceramics, and flexible PCB materials. Low heat, no damage.
Equipment Introduction:
The ultraviolet (UV) laser marking machine uses a short-wavelength laser beam to create permanent marks on the surface of various materials. Unlike long-wavelength lasers that rely on heat to vaporize material, UV lasers achieve marking by directly breaking the molecular bonds of the material—a process known as "cold processing."
This technique produces minimal thermal impact, extremely low edge chipping, and fine, clean lines. It can also mark distinct colors on materials that infrared lasers cannot affect, making it suitable for transparent and brittle materials such as glass.
Equipment Features:
Maintenance-free, no consumables, low operating cost
Laser lifespan: up to 20,000–30,000 hours
Requires a stable, room-temperature working environment
User-friendly software with multi-language interface, intuitive and easy to operate
Air-cooled for low-power models; water-cooled for high-power models
Clear and wear-resistant marks, with flexible content and fine detail
Adjustable pulse width and frequency for diverse marking effects
Controllable marking depth, adaptable to a wide range of products
Application Areas:
UV laser marking machines are especially suitable for ultra-fine processing in high-end markets. Typical applications include:
Cosmetics, pharmaceuticals, and medical devices
Precision materials such as thin ceramics, sapphire, polymers, and monocrystalline silicon
Marking on glass, TFT/LCD screens, plasma displays, plastic, textiles
Cutting and marking of flexible PCB boards
Micro-hole and blind-hole processing of silicon wafers
QR code engraving on LCD glass
Surface etching and piercing on glassware
Coating removal and marking on metal surfaces
Plastic keyboards, electronic components, gifts, and communication devices

1. Warranty Period:
Laser Machine: 18 months
Within 12 months, free replacement of parts, including the laser device.
For failures caused by non-human reasons, our company will send new accessories to customers for free, including the laser source.
Customers will need to send back faulty parts (laser source) first.
For other parts, there is no need to return them.
From 12 to 18 months, the customer will bear the laser cost and postage.
Both parties will share the postage cost for the return of the laser device.
The customer will send the faulty laser to our bonded warehouses in Jinan or Shenzhen, China. The purpose of this is to avoid complex customs procedures.
After 18 months, the laser source will cost, and the customer will need to buy the parts and cover the postage costs.
2. Laser Charging Instructions:
| Time | Laser | Remark |
| Within 12 months | Free replacement | Both parties pay the postal fee (If received within one month, customer bears no cost) |
| 12–18 months (During the warranty period) | Laser source cost × 0.2 | Both pay postage Send to bonded warehouse in China (Jinan/Shenzhen) |
| After 18 months (Out of warranty) | Laser source cost × 1.2 | Buy directly, customer pays postage |
1. What materials are suitable for UV laser marking?
It is ideal for high-precision applications on glass, ceramics, plastics, polymers, silicon wafers, LED chips, and PCBs.
2. Why is UV laser suitable for heat-sensitive or fragile materials?
UV laser is a cold light source with minimal thermal effect, avoiding deformation or cracking—perfect for delicate components.
3. What is the marking precision of a UV laser?
It can achieve micron-level precision with line widths as fine as 0.01 mm—ideal for QR codes, chip IDs, and electronics.
4. What colors can UV lasers mark?
They typically produce black (on white PVC), white (on black PVC), and gray (on projector glass), but do not support color marking.
5. Are safety precautions necessary when using UV lasers?
Yes. UV lasers can harm eyes and skin, so protective goggles are required. Enclosed or semi-enclosed systems are recommended.
