The CO2 laser marking machine or CO2 laser engraver is an engraving tool for working on organic materials. Hence it is widely applicable in wood engraving, paper cutting, acrylic bodies, and leather marking. Furthermore, the laser marking machine can mark non-metal inorganic materials, such as polymers, glass, leather, paper, acrylic, and plastics.

HeatSign offers high-quality CO2 laser marking machines running the latest laser technology. This page aims to show you what CO2 lasers are, the quality products available, and how to use them to get the best results.

How Does a CO2 Laser Marking Machine Work?

CO2 laser marking machines use CO2 lasers which are molecular gas lasers based on a gas mixture containing carbon dioxide (CO2), helium (He), nitrogen (N2), hydrogen (H2), water vapor, and xenon (Xe). The laser comes from a gas discharge due to DC or AC electricity or through Radio Frequency. The release into a metastable state of vibration excites the nitrogen molecules. Consequently, they transfer this energy to the CO2 molecules during a collision.

The machines emit infrared light at standard wavelengths of 9.6 and 10.6 µm. The laser beam from the laser tube evaporates the surface of the target material, thus exposing a deeper layer to create the mark you want.

Helium facilitates heat removal and returns the CO2 molecules to their ground state. Finally, the hydrogen and water vapor helps to re-oxidize carbon monoxide (formed during discharge) into carbon dioxide. This process is slightly different from laser cutters that need higher

Applications of CO2 Laser Engraving and Marking Machines

Unlike a fiber laser, which passes through glass, a CO2 laser can engrave glass. Moreover, these laser engravers can engrave other materials with light reflection/refraction properties, like acrylic. Furthermore, they are similarly useful for plastics and paper, resulting in deeper engravings with low discoloration. The infrared light CO2 lasers emit is also suitable for marking organic materials, including paper, leather, wood, and many plastics and ceramics. Furthermore, this laser can help remove thin layers of paint or ink from a substrate. Finally, you can mark metallic surfaces with absorptive coatings; heat-induced color changes can mark polymers.

How Much Does a CO2 Laser Engraver Cost?

Price is a major factor in selecting the best cutting-edge CO2 laser marker. HeatSign’s CO2 laser engraver costs between USD 2,000 to USD 8,000 and even more. It all depends on the major features of the device, such as the software, engraving material, laser tube, and laser power.

As a result, you need to choose the laser engraver that best suits your needs. Since you might not have enough time to search for the best laser-cutting technology, we are here to help you find the best and most economical solution for your engraving needs. So cut out your searching time and trust us with the laser engraving solution of your choice.


Can a CO2 Laser Engrave Metal?

Another popular question among our users is whether the CO2-laser engraver can mark metals. The simple answer is that it can mark certain metals and metallic coats, but unlike its proficiency in the acrylic and other organic materials field, it does not do very well on metals. As a result, other marking machines have laser tubes specially designed to work better on metals. You can contact us for more guidance on the topic.
