Handheld Laser Marking Machine – Model Differentiation and Real-World Factory Implementation Cases
Model Selection Guide:
👉 Handheld Laser Marking Machine: For on-site mobile operations, suitable for 0.05–0.2mm medium-to-shallow identification.
👉 High-Power Deep-Engraving Machine: For 0.05–3mm wide-range deep engraving, targeting heavy industry and powertrain deep-engraving applications.
Real-World Factory Implementation Cases
Case 1: Heavy-Duty Truck Parts Supplier – Solving Large-Part Identification Challenges
Materials processed: Frame numbers, thick carbon steel plates, welded frames
Heavy-duty truck parts are bulky and heavy, making it costly to transport them to a fixed marking station. Paint marking and steel stamping are prone to wear and fading.
Using the LZY handheld laser marking machine, the equipment is brought directly to the workpiece, eliminating the need to move heavy parts. Part numbers and traceable QR codes are engraved with durable, abrasion-resistant marks. The lithium battery supports offline operation, and the machine can be moved between workstations, effectively solving the identification problem for large parts while improving production efficiency.
Case 2: Major Construction Machinery Manufacturer – Achieving Long-Term Traceability for Construction Machinery Parts
Materials processed: Stainless steel plates, stainless steel structural parts, gears
Construction machinery parts require differentiated approaches: basic frames for on-site shallow traceability marking, and high-depth wear-resistant engraving for high-wear shells and core gear components. Xuzhou Construction Machinery Group introduced LZY high-power laser marking machines into its intelligent production line, using high-precision laser beams to assign unique digital identities to components. Since September 2024, the equipment has been in operation at Xuzhou's workshop, fully replacing traditional pneumatic marking equipment, integrating seamlessly with the intelligent production line, and completing the upgrade of long-term traceability identification for construction machinery parts.
Case 3: Automotive Manufacturer – Low-Noise, High-Efficiency Component Marking
Materials processed: Gears, alloy steel valve parts, heavy-duty truck chassis, aluminum alloy parts
An automotive manufacturer previously used pneumatic marking equipment, with a cycle time of approximately 18 seconds per part. However, the high noise and vibration not only affected worker health and the workshop environment but also limited flexible equipment layout. LZY's high-power laser marking machine rapidly marks high-depth components such as powertrain and transmission housings. The non-contact, low-noise process integrates with the MES system to automatically generate serial numbers for component traceability, achieving controllable 0.05–3mm engraving depth. With an external barcode scanner for one-click marking, it is well-suited for high-volume vehicle production.
