What is a UV Laser Marking Machine?
A UV laser marking machine creates excellent, long-lasting marks. It does this with a device that delivers high-powered ultraviolet light. The light cleaves the chemical bonds on the material’s surface in a low-heat process, yielding precise marks. This “cold marking” procedure is perfect for sensitive materials like glass, metals, and plastics because it mitigates damage to the material while yielding great results. Their usage is ubiquitous in electronics, medical devices, and packaging industries, where detailed and precise marking is routine.
How does a UV Laser Marking Machine work?
A UV laser marking machine uses a short wavelength ultraviolet laser beam to mark items. The ultraviolet laser very precisely focuses on an area 355 nanometers wide, or 0.355 microns, allowing for better accuracy than infrared lasers. The process starts when the ultraviolet laser is projected onto the material’s surface. The ultra-high energy photons erase the surface bonds, forming a permanent mark with no heat infliction—known as the ‘cold processing’ method.
As discussed in the previous paragraph, cold processing has minimal impact on the heated material, which helps in preventing deformation, discoloration, or melting. This allows the primary competing materials to remain undamaged and work without overlapping issues of effect and disassembly. Notably, this intense level of precision is particularly beneficial for industries needing intricate designs like QR codes, serial numbers, logos, tiny logos, or other emblems on delicate components like circuit boards or medical instruments.

The specific material and the marking requirements of the intended application determine which technologies to use.
Comparison of laser wavelengths used in UV and Fiber Laser
A UV laser usually works at a frequency of 355nm, which is in the ultraviolet region. Because the wavelength is very high, the cold marking technique, or marking with lasers with very little thermal impact (cold marking), is enabled. This makes UV lasers perfect for sensitive and precise surgical operations like marking delicate materials such as plastic, glass, silicon, et cetera without causing deformation or destruction.
By contrast with UV lasers, Fiber lasers are known to emit light of 1064nm in the near-infrared band. The longer wavelength will give deep access to metals and other hard surfaces. For this reason, fiber lasers are excellent and very efficient for industrial work such as engraving, cutting, and marking on steel, aluminum, copper, etc. Because of the power given and the increased effectiveness of these lasers, there will be a decline in the time needed to process and how long it is used, both vital in high-production factories.
One of the main distinguishing factors is the absorption features of the two types of lasers. Plastics and glass will fall under the broader category of converts that respond to the UV wavelength because they mark with more clearly defined borders. For bold and high-contrast markings, which are common in industrial sites, materials crafted from metal will be used, as metal is more active with the fiber laser’s infrared wavelength.
Selecting laser technology, be it UV or fiber, requires consideration of specific factors like the material’s thermal sensitivity, marking precision, processing speed, and material composition.
