Say Goodbye to Costly Consumables, Frequent Nozzle Clog, Erasable Codes, and Environmental Pollution: Experience Permanently Clear, Zero-Maintenance Industrial Marking
The Industrial Laser Marking Machine (Fly Laser Coder) (integrating high-energy laser generator $\rightarrow$ high-precision high-speed galvanometer scanning system $\rightarrow$ intelligent marking control software $\rightarrow$ photoelectric sensing and encoder synchronization tracking $\rightarrow$ ultra-fast surface ablation/reaction $\rightarrow$ high-definition permanent marking output) is an industrial-grade high-precision automation coding solution engineered to solve factory pain points such as high ink/solvent costs in CIJ coders, frequent downtime due to clogged nozzles, easily wiped/rubbed-off codes, and poor coding clarity in high-temperature or oily environments.
LANTU Machinery introduces an integrated industrial-grade flying / on-line laser marking solution. Equipped with industrial Fiber, Carbon Dioxide (CO₂), or Ultraviolet (UV) lasers, paired with high-response digital galvanometers and conveyor dynamic tracking systems, it enables millisecond-level precision coding on high-speed production lines. It prints production dates, expiration dates, QR codes, barcodes, vector LOGOs, and serial numbers on moving products. Whether marking on metal, rigid plastics, PET bottles, paper cartons, glass, rubber, or flexible pharmaceutical packaging, it delivers high-definition, tamper-proof, and rub-resistant automated coding.
As a source packaging and coding equipment manufacturer, LANTU Machinery has engineered this system—combining photoelectric detection, encoder speed measurement, vector path calculation, and laser power control—to be as intuitive as a standard printer. Operators only need to import graphics or text with one touch via the industrial touchscreen or PC software. As products pass the laser head on the conveyor, the machine automatically executes high-precision flying coding. With broad compatibility (line speeds up to 120–250 m/min), it completely eliminates traditional inks and solvents, achieving zero consumables, zero pollution, and ultra-low failure rates.
Choosing a reputable source manufacturer is crucial for your production line’s continuous stability. LANTU Machinery’s mature Fiber / CO₂ / UV laser configurations and dust-proof industrial cooling designs ensure your entire packaging line operates with high efficiency and long-term reliability.

Comprehensive Pre-Shipment Live Testing: Every machine undergoes high-speed flying tests on customer-specific sample materials before leaving the factory to ensure seamless integration on-site.

What Factors Should You Consider When Purchasing?
Material & Color Contrast Effect: Is your product glass, PET, metal, or paperboard? Do you require surface ablation, color change, or micro-engraving? (Free sample testing available).
Line Speed & Content Complexity: What is your conveyor belt speed (m/sec)? Are you printing a simple date line or complex 2D traceability codes / vector logos? (Determines required wattage like 20W/30W/50W/60W and galvanometer speeds).
Mounting Space & Stand Configuration: Will the laser be mounted over a conveyor belt or integrated inside a vertical form-fill-seal (VFFS) machine, flow wrapper, or labeling unit?
Fume Extraction Requirements: Does your material (e.g., plastics or paperboard) produce light dust or fumes during laser marking that require an industrial fume extraction unit?

Frequently Asked Questions (FAQ)
Q1: Does a laser marking machine truly require zero consumables?
Answer: Yes. Laser coders interact with material surfaces using focused light energy and require no inks, solvents, ribbons, or thinners. The only operational input is electrical power, eliminating recurring consumable expenses and ink contamination risks.
Q2: Will the code stretch, distort, or misalign on high-speed moving conveyors?
Answer: No. LANTU Machinery laser coders feature high-precision rotary encoders and high-frequency digital galvanometers. The encoder feeds real-time line speed data back to the controller, adjusting laser pulse frequency dynamically so that printed text and QR codes remain undistorted regardless of conveyor speed fluctuations.
Q3: Will the laser burn through or puncture thin plastic bags or PET bottles?
Answer: No, when properly configured. For delicate thin films or heat-sensitive substrates, we recommend UV cold-light lasers or specialized wavelength CO₂ lasers. Furthermore, the software allows precise tuning of laser power, pulse frequency, and marking speeds to achieve surface color change or ablation without damaging the underlying substrate.
