CO₂ Laser Marking Machine for Non-Metallic Materials with Operating Temperature 0-50°C
CO₂ Laser Marking Machines utilize gas laser technology to achieve high-precision industrial marking. The system employs a CO₂ gas mixture (with auxiliary gases like He and N₂) to generate a 10.64μm infrared laser beam through high-voltage discharge. This beam is amplified by a resonant cavity and focused via a galvanometric scanner and F-Theta lens into micro-sized spots (0.01-0.1mm diameter). Leveraging the photothermal effect, the laser vaporizes or carbonizes the material surface to create permanent marks. With modular design supporting flight marking (high-speed inline processing) and offline precision engraving, it is ideal for non-metallic materials (plastics, paper, glass, ceramics) and select metals (aluminum foil, stainless steel). Applications span pharmaceutical packaging anti-counterfeiting, tobacco product serialization, and electronic component coding.

CO₂ laser marking machines of working principle
1. Laser Generation:
- CO₂ gas mixed with auxiliary gases (He/N₂) fills a high-voltage discharge tube. High-voltage discharge induces gas discharge, exciting CO₂ molecules to emit 10.64μm laser light.
- The beam is amplified through a resonant cavity (e.g., parallel-plane or folded cavity) to produce stable TEM00 fundamental mode output with beam quality M² ≤ 10 and adjustable power (10-150W).
2. Material Processing:
- The focused laser beam scans the material surface in raster/vector patterns, vaporizing surface layers via energy density exceeding 10⁶ W/cm².
- Non-contact processing minimizes mechanical stress, achieving <0.1mm Heat-Affected Zone (HAZ) for fragile materials like silk or films.
