Introduction to CO2 Laser Marking

CO2 laser marking is a widely-used technology for engraving and marking applications, renowned for its precision and versatility. It utilizes CO2 gas, alongside electrical energy, to produce a concentrated beam capable of engraving a variety of materials with high precision.

Principle of CO2 Laser Marking

The principle of CO2 laser marking relies on the stimulation of carbon dioxide gas within a sealed tube to emit light in the infrared spectrum. This light is then focused through a lens to a small point on the surface to be marked. The intense heat from the laser beam causes the surface material to vaporize, resulting in high-contrast marks.

Technical Parameters

CO2 laser marking operates typically at a wavelength of 10.6 micrometers. The choice of power output, usually ranging from 10W to 100W, determines the depth and speed of marking. Beam quality and spot size are crucial, with spot sizes typically ranging from 50 to 200 micrometers. Engraving speed can reach up to 7 meters per second under optimal conditions.

Applications of CO2 Laser Marking

Common applications encompass industries such as packaging, electronics, and automotive. CO2 lasers are well-suited for organic materials, including wood, glass, textiles, and plastics. The technology is often used for barcoding, serial numbering, and branding purposes.
