UV Laser Marking Machine

Product Overview

The UV Laser Marking Machine is a high-performance, cold-processing laser engraving system designed for ultra-fine marking on heat-sensitive materials. Featuring a 355nm solid-state UV laser source with power options of 5W, 7W, and 10W, this machine delivers permanent, high-contrast marks without damaging the substrate

This is the industry’s fastest marking laser coding system, with a marking speed of up to 200 meters per minute for single-line 2mm-high numbers and letters – making it ideal for both medium-speed and high-speed production lines. With a 100×100mm marking area, 0.01mm minimum line width, and dual red-light focusing combined with UV positioning, this machine sets a new standard for precision and efficiency in industrial coding

Key Features and  Advantages

Industry’s Fastest Marking Speed – Up to 230m/min

With marking speeds reaching 200–230 meters per minute, this UV laser coder is the fastest in its class. Whether you're coding thousands of pharmaceutical packages per hour or marking high-speed production lines, this system keeps pace with your throughput without compromising quality.

355nm Cold Laser Technology – No Heat Damage

The 355nm UV wavelength is a true “cold” laser – it breaks molecular bonds directly rather than heating the material surface. This minimizes thermal impact, prevents discoloration, and eliminates the risk of cracking, melting, or burning on sensitive substrates like glass, thin films, and PCB boards..

Premium JPT Solid-State UV Laser Source

Equipped with a JPT solid-state ultraviolet laser source featuring an ultra-stable compact resonator structure. Key advantages include:

• High electro-optical conversion efficiency – Lower energy consumption

• Excellent beam quality – Consistent, precise marks every time

• High reliability and long lifespan – Rated for continuous operation

• Maintenance-free operation – No routine maintenance required

High-Precision Dual-Axis Galvanometer Scanner

The high-precision dual-axis galvanometer scanning system ensures rapid, accurate beam positioning across the entire marking field. This delivers distortion-free marks at high speeds, with exceptional consistency from batch to batch.

Dual Red-Light + UV Positioning – Fast & Accurate Setup

The 190mm focusing lens combined with dual red-light focusing and UV positioning enables operators to set the optimal focal distance in seconds. This intuitive visual guidance system reduces setup time, minimizes operator error, and ensures consistent mark quality across every job.

Unlimited Characters Lines

The system supports any number of characters and lines within the marking range, giving you complete flexibility for complex coding requirements – from multi-line text to intricate graphics and variable data.

Permanent, Tamper-Proof Marks

UV laser marks are permanent and indelible – they cannot be removed, smudged, or altered. This ensures full product traceability, brand protection, and compliance with regulatory requirements in pharmaceuticals, medical devices, and food packaging.

Seamless Integration & Flying Marking Capability

Designed for flying (on-the-fly) marking on moving production lines, this system integrates seamlessly with conveyors and automated packaging equipment. No need to stop the line – just mark and go.

Built for Demanding Industrial Environments

With stable operation across a wide temperature range and robust construction, this machine is engineered for reliable 24/7 performance in harsh factory conditions.
