CO2 Laser Marking Machine – High-Precision, Non-Contact Marking for Organic and Non-Metallic Materials

What is a CO2 Laser Marking Machine?

A CO2 Laser Marking Machine uses carbon dioxide gas as the laser medium. Inside the laser tube, a mixture of CO₂, nitrogen, and helium is electrically excited, generating infrared light at a wavelength of 10.64um. This wavelength is particularly well absorbed by organic and non-metallic materials, making CO₂ lasers an ideal choice for engraving, marking, and cutting applications on wood, glass, acrylic, leather, paper, and various plastics.

Unlike fiber lasers, CO₂ lasers excel in heat-based marking, creating high-contrast, permanent marks without direct contact, ensuring precision and durability while minimizing material stress.

Key Advantages of CO2 Laser Marking Machines

Wide Material Compatibility

Mark, engrave, or cut a variety of materials:

Organics: Wood, paper, leather, cork, bamboo

Plastics: ABS, PET, PVC, polycarbonate, acrylic

Glass & Ceramics: Logos, text, and decorative patterns

Rubber & Composites: Industrial seals, automotive parts

Permanent, High-Quality Marks

CO₂ laser beams create non-fading, abrasion-resistant markings, ideal for applications requiring long-lasting traceability, such as serial numbers, barcodes, and regulatory labeling.

Non-Contact, Low-Maintenance Operation

The marking process requires no inks, solvents, or mechanical tools, reducing operational costs. Since the beam never physically touches the material, there’s minimal wear on the machine and no risk of tool deformation.

High-Speed Productivity

Advanced galvanometer scanning heads allow marking speeds up to 8,000 mm/s, enabling high-throughput production without compromising precision.

3D and Curved Surface Marking

With optional dynamic focusing systems, CO₂ lasers can mark objects with curved, stepped, or inclined surfaces without distortion.

Typical Applications Of CO2 Laser Marking Machine

Industry	Use Cases
Packaging	Expiry dates, QR codes, logos on cartons, labels, and plastic films
Electronics	Circuit board labeling, plastic casings, component identification
Automotive	Marking on rubber seals, dashboard panels, and plastic components
Medical	Device branding, glass syringe scales, medical packaging labels
Crafts & Gifts	Custom engraving on wood, acrylic trophies, leather goods, and glassware

Specialized Marking Capabilities

Marking on Glass

CO₂ lasers create fine frosted effects or sharp white marks by generating microscopic surface fractures, perfect for branding glass bottles, jars, or drinkware without compromising structural integrity.

Synthetic Rubber Marking

Ideal for automotive wiper blades, belts, and seals, where high heat absorption ensures clear and permanent etching.

Wood & Cardboard Engraving

Burns crisp text or graphics directly into the surface for signage, packaging, or decorative purposes—marks will never smudge or peel.
