Laser Marking On The Fly, also known as dynamic laser marking, is a sophisticated technique that allows for precise marking, engraving, or coding on products as they move along a conveyor belt or production line. This technology eliminates the need to stop or slow down the production process for marking, significantly enhancing overall efficiency.

The key technical enabler of LMOF is real-time encoder feedback: a rotary encoder mounted on the conveyor measures the conveyor belt’s instantaneous travel speed and transmits this velocity data to the laser marking control system. FlyCAD’s motion tracking module uses this speed data to continuously adjust the galvanometer scanner’s trajectory, offsetting the mark path by the product’s movement during each scan line so that the final mark appears correctly aligned on the moving product surface — regardless of conveyor speed variations within the system’s tracking range

Core System Components

• High-Speed Galvanometer Scanning System with LMOF-Optimised F-Theta Lens: steers the beam across the product surface with real-time trajectory adjustment for moving targets
• Rotary Encoder Interface: receives real-time conveyor speed data for continuous motion tracking and mark trajectory compensation
• FlyCAD LMOF Control Module: manages encoder feedback integration, 9-axis synchronisation, and variable data population for LMOF operation
• MES/ERP Integration Interface (PROFIBUS, PROFINET, RS232): enables variable marking data to be received from production control systems without manual entry
• IP-Rated Industrial Enclosure: protects system components against the dust, moisture, oil, and vibration environments of industrial production lines

FlyCAD Laser Marking Software Features

Engineered for Seamless Production Integration

High-speed galvanometer scanning systems enable rapid, precise laser beam movement for high-quality markings at high line speeds. Advanced motion tracking through real-time encoder feedback keeps the laser accurately focused and trajectory-compensated on moving products, ensuring consistent marking quality regardless of conveyor speed variation. Synchronised laser firing with product movement marks products in real-time without halting the production line. Real-time adjustable marking parameters allow effortless adaptation to various products, sizes, and production speeds without mechanical changeover.

Boosted Production Efficiency

Continuous marking adds zero dwell time to the production takt — no interruption to the production line. Higher throughput is achieved by enabling rapid marking operations to meet high-volume demands that stop-and-mark alternatives cannot match. Eliminating the need for separate offline marking stations fully integrates marking into the production flow for streamlined, space-efficient processes. For Indian manufacturers in high-volume food, beverage, pharmaceutical, and electronics production, this throughput advantage directly translates to improved line OEE (Overall Equipment Effectiveness) and capacity for volume growth without adding marking-station bottlenecks.

Enhanced Marking Precision

Consistent marking quality is maintained even at high conveyor speeds through the encoder-linked trajectory compensation, producing uniform marks with no smearing, distortion, or positional error due to product motion. Complex mark content — serial numbers, QR codes, detailed logos, and intricate graphics — is rendered accurately on moving targets. The non-contact process minimises handling and risk of product damage, particularly important for fragile pharmaceutical glass ampoules, consumer electronics, and premium packaging.

Flexibility and Adaptability

Easy adjustment of mark settings for different product sizes, shapes, or materials allows rapid task changeover with minimal downtime. FlyCAD’s variable data management enables the system to switch between marking tasks — different batch codes, product variants, expiry date formats — without line stoppage, receiving updated mark data from the MES/ERP system automatically. Quality is maintained across varied production speeds within the system’s encoder tracking range.

Cost-Effective Operation

Lower operational costs result from the increased throughput efficiency that reduces the per-unit marking cost. Reduced labour needs through automation minimise the operator headcount required at the marking station compared with manual or semi-automatic marking methods. Minimal consumables — no inks, solvents, or wear parts — eliminate the ongoing consumable costs of inkjet and thermal transfer coding alternatives, while also eliminating the printer head cleaning, ribbon replacement, and substrate preparation requirements those technologies impose on line operators.

Food and Beverage Packaging

On-the-fly laser marking is extensively used for high-throughput packaging lines where real-time marking of expiry dates, batch codes, and traceability identifiers is essential. The system operates without interrupting line movement, offering non-contact, hygienic laser coding on PET bottles, aluminium cans, pouches, and laminated cartons. It complies with FSMA and FSSAI traceability requirements, ensuring product safety and regulatory alignment — directly relevant to India’s food and beverage manufacturers, dairy processors, and packaging operations requiring FSSAI-compliant batch and expiry coding at production line speeds.

Pharmaceutical and Medical Devices

LMOF systems deliver UDI-compliant, high-resolution markings on medical devices, blister packs, glass ampoules, and pill containers. The technology supports tamper-evident coding, anti-counterfeit marks, and precise serialisation, critical for pharmaceutical supply chain integrity. Markings are resistant to chemical sterilisation and abrasion, supporting ISO 13485 and 21 CFR Part 11 compliance frameworks — applicable to Indian pharmaceutical manufacturers, medical device producers, and contract packaging operations serving regulated domestic and export markets under CDSCO MDR 2017.

Automotive and Aerospace Components

In automotive and aerospace, LMOF ensures permanent identification of parts such as gears, housings, engine blocks, and turbine blades. VIN numbers, safety certification logos, lot codes, and inspection stamps are applied dynamically during assembly or post-machining without line stoppage. The system handles harsh substrates (steel, aluminium alloys, composites) with high contrast and zero thermal deformation, supporting IATF 16949 traceability requirements for Indian automotive Tier 1 and Tier 2 suppliers.

Electronics and Semiconductor Manufacturing

Laser marking on the fly enables micron-level identification on fast-moving production lines for PCBs, semiconductor wafers, connectors, and microelectronic casings. Serial numbers, QR codes, pin configurations, and ESD tracking labels are engraved without line stoppage. The system integrates easily with SMT lines and pick-and-place systems, maintaining high positional accuracy even at elevated speeds — supporting India’s expanding electronics manufacturing sector under the PLI scheme.

General Industrial and Tool Manufacturing

For industrial tools, hardware, and fabricated components, on-the-fly marking facilitates batch tracking, part traceability, and operator instructions directly on components like shafts, valves, and flanges. The system operates reliably under exposure to oil, dust, and vibration in IP-rated environments, with adaptability to changing part geometries and line speeds making it ideal for flexible manufacturing cells at Indian engineering components and precision manufacturing facilities.

Packaging, Labels, and Logistics

LMOF is ideal for continuous coding on corrugated boxes, film rolls, shrink wraps, and multi-layer label substrates. Dynamic barcodes, production timestamps, and promotional codes are marked even on reflective or semi-transparent materials. This eliminates inkjet and thermal transfer consumables and improves line OEE — relevant to India’s expanding FMCG, e-commerce logistics, and industrial packaging sectors requiring sustainable, maintenance-light coding solutions.

Jewellery and Luxury Goods

Authentication codes, brand logos, and anti-counterfeit hologram patterns are applied during production without line stoppage.
