CO2 Laser Machine: The Intelligent Solution for Laser Processing of Non-Metals

With the pursue of higher efficiency, accuracy and flexibility in the production lines, CO2 laser machine is considered as one best laser processing solutions that can meet various demands. Whether you’re engraving wooden crafts or marking packaging, cutting acrylic or personalizing leather goods, a CO2 laser system provides unparalleled speed, accuracy and repeatability.

Unlike regular mechanical processing, a CO2 laser provides non-contact processing, more clean edges, less maintenance and more design freedom. For companies looking to invest in a dependable laser marking machine for non-metal substances, there is nothing as cost-effective as CO2 laser.
In this in-depth guide, we dive into the working principle of CO2 laser machine, its advantages and applications, processing materials, and how to select the appropriate CO2 system based on your production requirements.

What Is a CO2 Laser System?

The carbon dioxide laser beam is in the infrared region, with a wavelength of approximately 10.6μm. This wavelength has, as maximum of its absorption curve, good penetration depth in UV and other high energy beams (K α from light elements), which is used for UV laser processing of organic and non-metal materials.Thanks to their features, CO2 laser systems are known as:

• High-speed processing
• Fine engraving quality
• Smooth cutting edges
• Stable performance
• Low maintenance
• Long service life
• Excellent versatility

How Does a CO2 Laser Work?

A CO2 laser produces infrared light within a gas laser tube filled with carbon dioxide, nitrogen, helium, among other gases. Mirrors direct the laser beam along an optical path where a lens focuses it to a small spot.

The laser energy, which is focused, heats, vaporizes, and alters the surface of material, resulting in accurate marking, engraving or cutting without any contact.

Such a non-contact method avoids wear and tear of tools and the quality of the products stays consistent for large-scale production.

Why a CO2 Laser Machine?

In comparison to the old approaches of engraving, CO2 laser technology have many benefits.
