Modern CO2 laser cutting machines
generate a laser beam inside a glass tube filled with carbon dioxide. The beam creates a chemical reaction with the gas, which increases its energy. This produces light and intense heat - sufficient to melt materials with high melting points. CO2 lasers are widely used for this purpose.
CO2 laser cutting machines for velcro can process a variety of materials, but the cut produced is shallower than that of a fiber laser. For this reason, you need to determine what your production requirements are, before deciding on a machine. Some CO2 laser cutting machines are expensive because of their great laser power, imported components, or larger working size.
Due to their infrared energy, CO2 lasers are invisible to the human eye. They are guided by red dots that help to position them precisely. Make sure the design you're creating fits within the laser's work area, and bring some extra material just in case you're not able to find what you're looking for.
