In today’s rapidly growing manufacturing and packaging industries, “product marking” is no longer just a simple “name tag.” From production date traceability to brand anti-counterfeiting and personalized customization, every demand is driving the continuous upgrade of marking technology. Among many marking devices, the CO₂ laser marking machine has gradually become the preferred solution for various industries thanks to its unique advantages.
Working Principle
The CO₂ laser marking machine uses carbon dioxide gas as the working medium. Once energized, the gas inside the resonant cavity generates infrared laser with a wavelength of 10.6μm. After being focused by an optical system, the highly concentrated energy acts on the surface of non-metal materials. Through instant vaporization, ablation, or surface modification, it forms clear and permanent marks.
Three Core Advantages
1. High-Precision Marking: Perfect for Details
Traditional ink printing often causes smearing and blurring, while the precision of a CO₂ laser marking machine can reach micron levels. Even tiny characters of 0.1mm or complex patterns can be presented clearly. Whether it is miniature parameters on plastic components or fine QR codes on paper packaging, the marks are formed in one step, with smooth edges and no burrs.
2. Eco-Friendly and Consumable-Free: Cost-Saving and Hassle-Free
Unlike ink marking, which requires regular replacement of ink and solvents, the CO₂ laser marking machine operates without any chemical consumables, needing only electricity. This eliminates environmental issues caused by ink leakage or solvent evaporation and reduces costs associated with consumables procurement and storage.
3. Wide Application Range: Ideal for Non-Metal Materials
From common plastics (PE, PVC, ABS), glass, and ceramics to paper packaging, leather, fabric, wood, and acrylic, the CO₂ laser marking machine can handle almost all types of non-metal materials.
Three Popular Application Industries
Food & Pharmaceutical Packaging Industry
If production dates, shelf life, or batch numbers are blurred or erased, it could cause serious safety incidents. The CO₂ laser marking machine ensures durable, high-temperature resistant, and friction-resistant marks on plastic packaging bags and paper medicine boxes. With no chemical residues, it fully complies with food and drug safety standards.
Electronics Industry
Many electronic components are small in size and require extremely high precision, which traditional marking methods struggle to achieve. The CO₂ laser marking machine can quickly mark model numbers, parameters, and anti-counterfeiting codes on these components. The marks are clear, durable, and tamper-resistant.
Cultural & Creative Products and Gifts
From engraving ancient poems on wooden bookmarks to customizing exclusive designs on ceramic cups, or embossing names on leather notebooks, the CO₂ laser marking machine can precisely reproduce design details, turning ordinary gifts into “unique personalized treasures.”
