Cold Laser Engraving
Also known as a blue laser beam, this technology has the ability to engrave with low heat. The machine's light wave, or ultraviolet spectrum, is one of the main reasons the technology can engrave on different materials because it doesn't heat the surface of the material like fiber optics and carbon dioxide do. It allows UV lasers to make clear and high-precision markings on all plastics and other materials that react poorly to heat.
There are thousands of different plastic combinations, all of which can be engraved with UV laser technology, these are the most common plastic engravings for our laser engravers.
Polyvinyl Chloride (PVC)
Polylactic acid (PLA)
Acetal (Polyoxymethylene, POM)
ABS (Acrylonitrile Butadiene Styrene)
Other plastics are not mentioned here.
UV lasers can engrave and mark metals, but don't always have the same effect as fiber laser engravers. While fiber lasers can etch deeply and produce crisp results on metal surfaces, UV lasers have problems engraving painted metals or highly reflective metals like copper. Check out the list of metals that UV lasers can engrave below.
Ultraviolet laser is a full-intersection technique that is ideal for engraving plastics and some common metals as a whole. However, one of the significant advantages of this machine was that some non-metallic materials such as wood could be engraved at the time. This machine can do amazing carvings on different wood surfaces. It cannot etch as deep and fast as a CO2 galvo laser, but it produces bright and beautiful markings.
Our UV laser machines can also engrave some garments, especially those rich in synthetic fibers. However, if you want to engrave on a specific garment, we can do a test to check the engraving result before you buy our machine.
UV lasers are one of the techniques that can engrave on glass surfaces without cracking or overheating the material. You can create stunning engravings and patterns without shards of glass.
paper and cardboard
The engraving of cardboard also depends on the material and the result is different from the usual engraving of CO2 machines. When the carbon dioxide machine carbonizes the surface of the cardboard or paper material, the UV light creates a chemical reaction that creates marks on the surface of the material, so we can engrave white on the cardboard surface, and if we want to engrave on black cardboard, we can still get clear comparison.
