CO₂ laser marking machines of equipment overview
CO₂ Laser Marking Machine CO₂ Laser Fully Automatic Image & Text Engraving
CO₂ laser marking machines utilize a gas laser (with carbon dioxide molecules as the active medium) to perform non-contact permanent marking via 10.6μm wavelength laser-material interaction. Primarily designed for non-metallic materials, they are widely used in packaging, electronics, medical industries, etc.
Core Components:
- CO₂ Laser Tube: RF-excited or sealed glass tube (10W-200W power range)
- Galvanometer System: High-speed scanning mirrors (±0.003mm precision)
- Control System: Supports vector files from CorelDRAW/AutoCAD
- Cooling System: Air-cooling (≤60W) or water-cooling (high-power models)
- Focus Lens Assembly: ZnSe lenses (2.5"-5" focal length) for marking resolution

CO₂ laser marking machines of working principle
1. Laser Generation:
- High-voltage electric field excites CO₂ molecules to emit 10.6μm infrared laser.
2. Beam Delivery:
- Mirrors and beam expanders direct light path to galvanometer-scanned focusing lens.
3. Material Interaction:
- Laser energy absorbed by non-metals (organics/plastics) causes ablation/carbonization/foaming, creating high-contrast marks.
Technical Features:
- Thermal Processing: Optimal for light-absorbing non-metals (requires coatings for metals).
- Wavelength Advantage: 10.6μm wavelength achieves >80% absorption in most polymers.
CO₂ laser marking machines of features & advantages
1. Non-Metal Specialization:
- Outperforms fiber/end-pumped lasers on wood, acrylic, glass, etc.
2. Low Operational Cost:
- CO₂ tubes last 20,000-50,000 hours; lower replacement cost than solid-state lasers.
3. High Adaptability:
- CO₂ laser marking machines marks curved/irregular objects (with rotary axes).
4. Consumable-Free:
- No inks/chemicals, meeting environmental standards.
Competitive Comparison:
- vs Fiber Lasers: CO₂ is faster/cheaper for non-metals but cannot directly mark metals.
- vs UV Lasers: CO₂ offers higher power for deep engraving; UV suits heat-sensitive materials (e.g., PET).
CO₂ laser marking machines of applications
1. CO₂ laser marking machines with packaging:
- Date codes on cartons, batch numbers on plastic bottles (FDA-compliant, non-toxic).
2. Electronics:
- logos on plastic housings, keyboard legends (no mechanical stress).
3. Artware:
- Wood carvings, leather branding (artistic detailing).
4. Medical Devices:
- Graduation marks on syringes (medical-grade PP/PE).
5. Food Industry:
- CO₂ laser marking machines is surface marking on eggs/fruits (non-penetrative cold processing).
Special Cases:
- Transparent acrylic backside engraving: CO₂ laser marking machines creates 3D effects via laser scattering.
- Anodized aluminum marking: Requires specialty coatings (e.g., LaserMark®).
CO₂ laser marking machines of sample display
CO₂ laser markers remain irreplaceable for non-metal processing due to their cost efficiency and material versatility. Future trends include higher power (300W+) and smart integration (e.g., vision positioning) to expand applications in flexible material processing.
