CO2 Laser Marking Solution for Non-Metal Packaging and Labeling

As precision manufacturing continues to evolve, CO₂ laser marking machines have become essential for non-metal processing. Leveraging high-purity carbon dioxide gas as a laser medium, these machines generate a 10.64μm infrared laser beam through high-voltage discharge. This wavelength is easily absorbed by non-metal materials, making CO₂ laser marking ideal for organic substrates. With a galvanometer-driven scanning system and F-Theta lens, the laser beam is precisely focused and guided to perform high-speed, non-contact marking through surface vaporization or chemical reaction, with no consumables, no contact, and minimal environmental impact.

Why Choose CO2 Laser Marking Machines

High Precision: Consistent beam quality enables sharp and clear markings on even the smallest components, reducing thermal deformation common in mechanical processing.

Fast Throughput: Millisecond-level response time via galvanometer scanning significantly boosts productivity for high-speed production lines.

Smart Control: Advanced software allows users to input vector graphics, serial numbers, or pull data directly from databases, enabling one-click marking with minimal operator intervention.

Long-Term Stability: Equipped with constant current and voltage systems, CO₂ laser markers operate reliably over extended periods, reducing downtime and maximizing equipment utilization.

Diverse Applications Across Industries

CO₂ laser marking systems serve a wide range of sectors:

Pharmaceuticals: Precise marking on glass vials and plastic syringes ensures traceability and regulatory compliance.

Food Packaging: Enables clear, non-toxic QR code and batch coding on PET bottles, cartons, and paper labels.

Electronics: Stress-free marking on plastic connectors and silicone components preserves sensitive part integrity.

Creative Materials: Delivers detailed custom engraving on bamboo, leather, and wood for personalized crafts and cultural products.

The Role of CO2 Laser Chillers in System Stability

During operation, CO₂ laser tubes generate significant heat. To maintain stable performance and prevent overheating, an industrial CO₂ laser chiller is essential. TEYU's CO₂ laser chiller series offers both constant and intelligent temperature control modes, along with features such as digital setpoint adjustment and alarm displays. Built-in protections include compressor delay start, over-current protection, water flow alarm, and high/low temperature alarms.

In case of abnormal conditions, such as overheating or low water levels, the chiller automatically triggers alarms and initiates protective actions to safeguard the laser system. With a highly efficient cooling circulation system, the chiller enhances energy efficiency, minimizes heat loss, and operates quietly, ensuring continuous and reliable laser marking.

Conclusion

CO₂ laser marking is transforming how industries label, trace, and customize non-metal materials. With its non-contact, high-speed, and high-precision capabilities, combined with intelligent control and broad application potential, it is an ideal solution for modern, eco-conscious manufacturing. Pairing your CO₂ laser system with a reliable TEYU industrial chiller ensures long-term performance, energy efficiency, and maximum productivity.
