With the growing demand for intelligent manufacturing and refined processing, CO2 laser marking machines have become the core technical equipment in the field of non-metallic material processing due to their high efficiency, precision and environmental protection.
一、 The core principle of CO2 laser marking machines
CO2 laser marking machines use high-purity carbon dioxide gas as the working medium, and excite gas molecules through high-voltage discharge of electrodes to generate far-infrared lasers with a wavelength of 10.64 microns. Lasers of this wavelength have excellent absorption characteristics for non-metallic materials. After the laser beam is deflected at high speed by the galvanometer system and focused by the F-Theta mirror, it can act accurately on the surface of the material, forming a permanent mark through gasification or chemical reaction, realizing “non-contact, non-consumable” clean processing.
二、 Technical features of CO2 laser marking machine:
- Ultra-high precision: The laser beam quality output by the base mode is stable, and the minimum line width can reach 0.01mm. Even on micro-small workpieces, clear marking can be achieved, avoiding the thermal deformation problem of traditional mechanical processing.
- Extremely fast response: The galvanometer system supports a scanning speed of more than 10 meters per second, and the processing time of a single piece is calculated in milliseconds, which significantly improves the efficiency of the production line.
- Intelligent operation: With dedicated control software, it supports vector graphics, serial numbers and database direct connection functions to realize the automated process of “one-click marking”.
4. Long-lasting stability: The constant current and constant voltage control system ensures continuous operation of the equipment, with an average failure-free time of more than 20,000 hours and low maintenance cost.
三、 Industry applications of CO2 laser printers
- Pharmaceutical industry: engrave batch numbers and expiration dates on glass medicine bottles and plastic syringes to meet medical-grade alcohol-resistant wiping and high-temperature sterilization requirements.
- Food packaging: mark traceability QR codes on the surface of PET bottles and paper boxes to replace ink printing and eliminate the risk of chemical pollution.
- Electronic components: stress-free marking of plastic connectors and silicone buttons to avoid physical damage to precision parts.
- Craft products: realize personalized engraving on natural materials such as bamboo, wood, and leather, and open up a new model of customized production of cultural and creative products.
四、 Compared with traditional silk screen printing, inkjet coding and other technologies, the core advantages of CO2 laser coding machines are highlighted:
- Environmental upgrade: abandon ink and chemical etching agents, reduce VOCs emissions, and comply with EU RoHS and other environmental standards.
- Cost optimization: no need for plate making and mold change, support small batch flexible production, and reduce comprehensive energy consumption by more than 40%.
3. Quality transition: The mark has wear resistance and acid and alkali resistance, and its service life is synchronized with the product body, which helps brand anti-counterfeiting and traceability.
With the promotion of green and intelligent manufacturing in Made in China 2025, CO2 laser marking machines are accelerating their iteration towards modularization and intelligence. The next generation of equipment integrating AI visual positioning and industrial Internet of Things will further improve its adaptability in flexible production lines. According to industry forecasts, the global market size will exceed US$1.5 billion by 2025, becoming a new growth pole in the field of precision machining.
In short, from daily necessities to high-end medical devices, High-speed laser marking machines are redefining the marking process of non-metallic materials. Its technological innovation not only promotes industrial upgrading, but also provides an innovative model for sustainable development with green and efficient production methods. In the wave of Industry 4.0, this technology will continue to release its potential and enable a wider range of application scenarios.
