Product Overview

The UV Laser Marking Machine is designed for high-precision, non-contact marking and engraving across a wide range of heat-sensitive and delicate materials. Utilizing a 355nm ultraviolet laser beam, this system achieves ultra-fine markings with a minimum line width of 0.03mm and character height as small as 0.3mm.

It features advanced beam quality (M² <1.1) and supports a fast marking speed of up to 10,000 mm/s, with repeat positioning accuracy of ±0.003mm. The machine is cooled by an internal water circulation system, maintaining optimal performance during extended use.

Perfect for marking plastics, glass, flexible PCBs, silicon wafers, and coated metals, it delivers crisp, permanent results without material deformation or heat damage. It is widely used in electronics, cosmetics, pharmaceuticals, food packaging, and precision engineering industries.

Features & Benefits

Ultra-Fine Marking Precision

Utilizes a 355nm ultraviolet laser source to achieve ultra-fine beam focus.  With a minimum line width of 0.03mm, it enables high-resolution marking of micro text, QR codes, and logos—perfect for high-end precision processing.

Cold Processing with No Thermal Damage

As a “cold light” process, UV laser marking causes no thermal stress or material deformation, making it ideal for heat-sensitive materials like plastics, glass, films, and flexible PCB boards.

High Accuracy & Repeated Precision

Equipped with auto-focus and precision optics, the system ensures consistent marking with ±0.003mm repeat accuracy, even during high-speed, continuous operations.

High-Speed Marking for Mass Production

With marking speeds of up to 10,000mm/s and a marking area of 150×150mm or 180×180mm, this machine is designed to handle large-volume production with maximum efficiency.

Advanced Circuit Design & Full Protection System

Incorporates full-bridge inverter circuits and negative feedback power control.  Built-in protections against over-voltage, over-current, overheating, and water shortage ensure safe and stable operation.

Powerful Water Cooling System

Features a high-efficiency industrial-grade water cooling system with large heat sinks and a precise temperature control range of 25℃ ± 0.1, ensuring optimal performance and extended laser lifespan.

User-Friendly Operation Interface

Supports a wide range of file formats (DXF, BMP, PLT, etc.) and integrates easily with automated production lines, conveyor belts, and vision positioning systems.

Eco-Friendly & No Consumables

No need for ink or solvents.  UV laser marking is clean, odorless, and pollution-free, producing permanent, high-contrast marks resistant to heat, abrasion, and chemicals—ideal for industries like food and pharmaceuticals.

Versatile Application Capabilities

Suitable for marking on a wide range of materials and industries including cosmetic bottles, food containers, medical packaging, PCBs, silicon wafers, glass, plastic parts, electronics, and automotive components.

Compact Design & Flexible Integration

With a compact machine footprint (600×800×1400mm) and optional conveyor system, it can be easily integrated into existing production lines or customized workstations.
