A CO₂ laser marking machine is a type of laser system that uses a carbon dioxide (CO₂) gas laser to mark, engrave, or cut various materials. It operates at a wavelength of 10.6 µm, making it highly effective for non-metallic materials like wood, leather, plastic, glass, and paper.

How CO₂ Laser Marking Works?

The machine directs a high-energy laser beam onto the surface of the material. The beam either removes material (engraving) or creates a contrast (marking) by altering the surface properties. The process is contactless and does not require inks or additional consumables.

Key Features & Benefits

✔️ Versatile – Works on organic materials (wood, leather, glass, acrylic, paper, etc.).
✔️ High Precision – Creates intricate designs, barcodes, serial numbers, and logos.
✔️ Non-Contact Process – No physical wear on the marking head.
✔️ Fast and Efficient – Ideal for high-speed production lines.
✔️ Environmentally Friendly – No ink, chemicals, or consumables required.

Applications of CO₂ Laser Marking Machines

🔹 Wood Engraving & Cutting – Signboards, furniture, decorative items.
🔹 Acrylic & Plastic Marking – Displays, promotional items, product branding.
🔹 Glass & Crystal Engraving – Wine glasses, trophies, awards.
🔹 Leather & Fabric Marking – Wallets, belts, shoes, clothing.
🔹 Packaging Industry – Date codes, barcodes, QR codes, batch numbers.

CO₂ Laser vs. Other Laser Marking Machines

Choosing the Right CO₂ Laser Marking Machine

When selecting a CO₂ laser marking machine, consider:
✔ Power Output – Ranges from 20W to 150W+ (higher power for deeper engraving).
✔ Work Area Size – Varies from small desktop models to large industrial machines.
✔ Cooling System – Air-cooled (smaller systems) or water-cooled (higher power).
✔ Software Compatibility – Supports vector files (AI, DXF, PLT) and engraving software.
✔ Automation Features – Conveyor systems for industrial use.
