UV/ CO2 Laser Marking Machine

UV/ CO2 Laser Marking is a process in which UV or CO2 lasers utilize a highly absorptive wavelength (355 nm) to mark parts. This high absorption rate lets UV lasers make cold marking guaranteeing that no extra heat stress is applied to materials, including those with high reflectance such as silver, gold, and copper. This type of mechanism decreases soot and burrs produced from typical marking and processing. The UV/ CO2 laser marking process is extremely fine and controlled, making it excellent for delicate or accurate work.

UV/ CO2 Laser marking machines are marking machines utilising UV lasers or Co2 lasers to mark numerous materials with minimal heat damage and excellent contrast, especially on plastic and organic materials.

UV lasers have an operating range at 355 nm that are shorter wavelength. A UV laser’s wavelength is one-third of standard wavelength lasers which is achieved by passing a standard wavelength laser at 1064 nm through a non-linear crystal, reducing it to 532 nm, this is then passed through another crystal, decreasing its wavelength further, down to the working 355 nm. UV lasers shoot high-energy photons in the ultraviolet spectrum that break down the chemical bonds in the material which causes the material to undergo non-thermal process damage. This type of engraving does not create thermal deformation (heat damage) on the materials.

CO2 systems are among the most commonly utilised lasers for industrial engraving and cutting. CO2 laser cutters make use of CO2 gas in a sealed tube acting as the laser medium which functions at the 10,600nm wavelength. CO2 lasers normally come in a plotter format and also available in a sealed unit. CO2 laser cutters and engravers are exceptional choices for organic materials like wood, paper, rubber, glass and ceramic and cutting acrylic and other plastics.

The features of UV/ CO2 Laser Marking Machine are:

• Mark quickly and precisely.
• User-friendly software for creating and editing engraving designs is.
• Provides non-contact, permanent laser marking onto almost any type of metallic and non-metallic material.
• Visible ‘Pilot’ beam displays the laser marking location for fast, accurate setup.
• Offer permanent, high grade readable codes irrespective of product positioning.
• Excellent beam quality, small focused laser spot, small heat affected zone enabling super fine marking.

UV/ CO2 Laser Marking Machines are extensively used for marking, etching and engraving of hard materials, on a variety of materials such as aluminium, stainless steel, rubber and polymers. UV/ CO2 Laser Marking Machines are generally used to identify parts and products with 2D barcodes (data matrix codes or QR codes), alphanumerical serial numbers, VIN numbers, and logos. UV/ CO2 laser marking machines are utilised in a wide range of industries for marking smooth, hygienic marks essential of medical device manufacturers, to mark delicate components, like circuit boards and silicon wafers, with less waste.
