Technical Specifications

Product Features

High-Speed Galvanometer for Flying Marking

The UV laser marking machine features a high-speed galvanometer that enables engraving line speeds up to 12,000mm/s. This allows the system to perform flying laser marking on moving production lines, marking items on the fly without stopping the conveyor. For manufacturers operating high-speed assembly lines, this capability translates into uninterrupted production flow and significantly higher throughput per shift compared to traditional stationary marking approaches.

Multiple Power Configurations for Versatile Applications

Available in 10W, 20W, and 30W power options, the UV laser marking machine adapts to different material types and throughput requirements. The 5W and 10W variants are well-suited for marking plastics, packaging materials, and coated metals where surface contrast is the priority, while higher power options handle deeper engraving on metal surfaces. This flexibility allows production facilities to standardise on a single platform across multiple product lines.

Ultraviolet Cold Processing Technology

The 355nm ultraviolet wavelength produces minimal thermal effect on the material surface, reducing the risk of deformation, discoloration, or burn marks. This cold-processing characteristic is particularly advantageous when marking heat-sensitive materials such as plastic packaging, electronic components, and coated surfaces. Where fiber lasers may char or melt thin plastics, the ultraviolet laser marking machine delivers clean, crisp marks without compromising substrate integrity.

Micron-Level Precision and Repeatability

With a minimum line width of 0.01mm and repeat accuracy of ±0.001mm, the UV laser marking machine delivers consistent, high-contrast marks across every workpiece. Text, serial numbers, QR codes, and barcodes are engraved with clarity and permanence, ensuring traceability and compliance in regulated industries. The combination of tight beam quality (M² < 1.5) and short pulse width (10–50ns) enables the UV laser marker to produce fine details that remain legible under magnification.

Stable Operation and Low Maintenance Design

The water-cooling system maintains stable laser output during extended production runs without thermal drift. Combined with a straightforward optical path and sealed laser cavity, the ultraviolet laser marking machine requires minimal routine maintenance — primarily periodic cleaning of optics and coolant checks. This low-maintenance design reduces total cost of ownership for facilities running multiple shifts and demanding high machine uptime.

Comprehensive Accessory Kit for Quick Deployment

Each UV laser marking machine ships with a complete set of accessories: a UDisk for parameter storage and transfer, positioning bar for rapid workpiece alignment, power and USB cables for connectivity, hex wrench for mechanical adjustments, a color aluminum sheet for test marking, safety goggles for operator protection, and a foot switch enabling hands-free triggering during production. These accessories allow operators to set up and begin production marking with minimal delay.

Business Value

For manufacturers operating automated production lines, the UV laser marking machine represents a direct path to higher throughput and lower per-unit marking costs. By integrating directly into existing conveyor systems and supporting flying marking, the machine eliminates the need for separate offline marking stations and reduces manual handling between processes.

The combination of high marking speed (≤12,000mm/s) and repeatable precision (±0.001mm) means manufacturers can maintain tight quality control without sacrificing cycle time. Each mark is consistently placed and legible, reducing rework and scrap from misaligned or illegible codes. In high-volume environments where thousands of parts are marked per shift, even fractional improvements in first-pass yield translate into significant cost savings over a production year.

Low maintenance requirements further improve return on investment. The water-cooled UV laser source supports extended operational lifespans, and the straightforward design allows operators to perform routine checks without specialised training. For production facilities running multiple shifts, this translates into higher machine uptime and predictable operating costs without the need for dedicated laser engineers on every shift.

The UV laser marking machine also supports flexible production needs. Quick parameter adjustments allow the same machine to handle different product SKUs, materials, and marking content — from expiry dates on food packaging to serial numbers on electronic components — with minimal changeover time. This flexibility is particularly valuable in contract manufacturing environments where production runs change frequently and setup speed directly impacts profitability.

Additionally, the cold-processing nature of the 355nm wavelength eliminates the need for consumables such as inks, solvents, or marking chemicals. There are no ink cartridges to replace, no solvents to handle, and no drying stations required. For production managers evaluating total operational cost, the consumable-free operation of the UV laser marking machine provides a clear advantage over inkjet and thermal-transfer printing alternatives over the machine’s service life.

Applications

Food and Beverage Packaging

In food and beverage production lines, the UV laser marking machine marks expiration dates, batch numbers, and QR codes directly on packaging materials including plastic films, cardboard, cardboard boxes, and coated paper. The cold processing feature ensures the packaging integrity is not compromised — no burn-through, no melting, and no risk of contamination from marking byproducts. The high-speed marking capability keeps pace with fast-moving conveyor systems handling hundreds of packages per minute.

Daily Chemicals and Personal Care Products

Manufacturers of personal care products — shampoo bottles, cosmetic containers, cleaning supplies, and soap packaging — use the UV laser marker to apply permanent product information and branding on plastic and glass surfaces. The high-contrast, smear-proof marks withstand handling, shipping, and retail display without fading. Unlike ink-based marking that may smudge during filling or transport, laser marks are permanent and cannot be altered after application.

Electronics and Semiconductor Components

The electronics industry requires precise, legible marks on small components without damaging sensitive circuitry. The UV laser marking machine’s 0.01mm minimum line width and ±0.001mm repeat accuracy enable clear marking of serial numbers, date codes, logos, and 2D data matrix codes on PCBs, connectors, chips, casings, and passive components without thermal stress to adjacent elements. The cold-processing ultraviolet wavelength is especially critical for double-sided boards and components with tight tolerance specifications.

Automotive Parts and Supply Chain Traceability

Auto parts manufacturers rely on the UV laser marking machine for permanent traceability marks on metal and plastic parts — including brackets, sensors, connectors, under-hood components, and interior trim pieces. Marks remain legible through the entire supply chain and throughout the product lifecycle, supporting warranty tracking, recall management, and quality tracing back to individual production batches.

Pharmaceutical Packaging and Medical Device Marking

For pharmaceutical packaging and medical device components, the UV laser marking machine delivers the precision and permanence required for regulatory compliance. Batch numbers, expiry dates, and unique device identifiers (UDIs) are applied without solvents or inks, eliminating contamination risk. The non-contact marking process also preserves sterile packaging integrity, making the ultraviolet laser marking machine suitable for cleanroom and controlled-environment production areas.

Rubber and Industrial Components

Tire manufacturers, rubber gasket producers, and industrial component fabricators use the UV laser marking machine to apply identification marks, specifications, and logos directly onto rubber surfaces. The cold-processing nature of 355nm laser light prevents the rubber from becoming sticky or degraded at the marking site — a common problem with CO₂ and fiber lasers on certain rubber compounds.
