Small UV Laser Marking & Engraving Machine
Product Overview
Our Small Portable UV Laser Marking Machine is a compact, industrial-grade desktop solution engineered for ultra-fine processing. At its core is a 355nm ultraviolet laser source utilizing advanced third-order harmonic generation technology. This design achieves a significantly smaller focused spot size compared to traditional infrared lasers, enabling true “cold processing” that minimizes thermal effects and mechanical deformation on workpieces. It is the ideal tool for applications demanding the highest levels of precision and mark quality with minimal material interaction.
Technology & Core Applications
How It Works: Cold Ablation Precision
The key to its performance lies in its short 355nm wavelength, which provides higher photon energy. This allows the laser beam to be focused to a micron-level spot (typically <15μm). Material removal occurs primarily through photochemical ablation, where molecular bonds are broken directly by the high-energy UV photons, rather than through thermal melting. This process virtually eliminates heat-affected zones, burrs, micro-cracks, and thermal stress, making it perfect for stress-free, micro-scale machining.
Primary Application Industries
This machine excels in high-value manufacturing sectors requiring flawless, permanent marks on sensitive or challenging materials:
- Medical Devices & Precision Instruments: Permanent marking of surgical tools, implantable devices, and precision sensors with micro QR codes, UDI codes, or logos, without compromising material integrity or biocompatibility.
- Semiconductor & Electronics: Fine marking and graphic patterning on silicon wafers; precise cutting and drilling of flexible printed circuits (FPC); and high-contrast marking on ceramic substrates and chip packages.
- Advanced Packaging & Anti-Counterfeiting: High-speed, wear-resistant micro-marking for traceability and authentication on pharmaceutical packaging, cosmetics, luxury goods, and security labels.
- Specialty Material Processing: Clean cutting of thin plastic films and polyimide; scribing and dividing of glass and sapphire cover plates with smooth, chip-free edges.
Key Advantages & Benefits
- Unmatched Fineness & Quality: The short UV wavelength enables micron-level (<15μm) marking resolution, producing exceptionally sharp edges, smooth surfaces, and high-contrast marks ideal for intricate graphics and tiny fonts.
- True “Cold Processing” Minimal HAZ: The photochemical ablation mechanism drastically reduces thermal damage, preventing burning, melting, or deformation of heat-sensitive materials like thin plastics and certain coatings.
- Superior Material Versatility: Effectively processes materials that are difficult or impossible for IR lasers, including highly reflective metals (gold, silver, copper), most plastics, glass, ceramics, and engineered composites like FR4.
- Compact & Flexible Integration: The “Small Portable” design philosophy results in a minimal footprint, allowing for easy integration into existing lab benches, cleanrooms, or production lines, and enabling flexible deployment across multiple workstations.
- Reliable Industrial Performance: Built with industrial-grade components and a robust laser source, it ensures stable, maintenance-friendly 24/7 operation for both R&D prototyping and high-volume manufacturing environments.

We also offer another model of UV flying laser marking machine, allowing you to choose the most suitable solution based on your production volume and business requirements. Designed for high-speed production lines, this UV flying marking system delivers permanent, high-precision marking without damaging the substrate. By using ultraviolet laser technology, it produces clear and high-contrast marks on heat-sensitive materials such as plastics, films, glass, paperboard, and coated surfaces. Compared with traditional inkjet or thermal marking methods, it operates without consumables, reduces maintenance, and lowers long-term operating costs. Its minimal heat-affected zone ensures consistent marking quality even at high line speeds, making it ideal for batch codes, dates, QR codes, barcodes, and full traceability information.
