UV laser marking machine is a type of laser engraving system with 355nm ultraviolet laser wavelength for cold laser engraved projects, due to a high repetition rate, it is especially used for etching plastics (ABS, PA, PE, PP, PS, PC, PLA, PVC, POM, PMMA), silicon, ceramic, glass, wood, metal, and papers. UV laser engraver can reach very high speeds which are indispensable for short cycle times in industrial manufacturing environments. You can also use UV laser marking system to cut leathers. With high peak powers, Ultraviolet laser marking machine can be used for fine marking and structuring with drastically reduced risk of microfracture on ceramics and glass. It is also known as UV laser engraving machine, UV laser engraver, UV laser etching machine, UV laser etcher, UV laser marker, UV laser marking system, UV laser printing machine, UV laser stippling machine.


Ultraviolet laser marking machine uses a laser beam to make permanent marks on the surface of various materials. The effect of marking is to expose the deep material through the evaporation of the surface material, or to "carve" traces through the chemical and physical changes of the surface material caused by light energy, or to burn off the partial material through light energy to show the required etching patterns, text. It is developed by using a 355nm UV laser. Compared with infrared lasers, this machine adopts three-stage intracavity frequency doubling technology. Compared with infrared lasers, the 355 UV light has a very small focus spot, which can greatly reduce the mechanical deformation and processing of materials, and the heat influence is small.

Ultraviolet laser marking is a type of cold etching. The process of ultraviolet laser etching is called "photoetching" effect. "Cold engraving" has high-energy (ultraviolet) photons that can break chemical bonds in materials (especially organic materials) or surrounding media. To cause the material to undergo non-thermal process destruction. There is no heating or thermal deformation on the inner layer and nearby areas of the engraved surface.


Ultraviolet laser marking machine has high performance and ultra-fine features, suitable for high-precision marking of precision electronic components, plastics, leather, and woodworking projects. UV laser etcher is especially suitable for ultra-fine marking the surface of packaging bottles of cosmetics, medicines, food and other polymer materials, with fine effects and clear and firm markings. It is better than ink printing without pollution. It can also be used for high-speed division of glass materials and complex pattern cutting of silicon wafers.

Marking and dicing of flexible PCB boards.

Micro-hole and blind hole processing of silicon wafers.

LCD liquid crystal glass two-dimensional code marking, glassware surface punching, metal surface coating marking, plastic buttons, electronic components, gifts, communication equipment, building materials and more.

Ultraviolet laser etching machine shows extremely high absorptivity when applied to resin and brass, and it also has an appropriate absorptivity when processing glass. Only the expensive excimer laser (wavelength 248nm) can get better overall absorption rate when processing these main materials. This material difference makes UV lasers the best choice for various PCB material applications in many industrial fields, from the production of the most basic circuit boards, circuit wiring, to the production of pocket-sized embedded chips and other advanced processes.


UV laser engraving machine can provide an excellent beam quality for micro laser marking applications (electronics, microchips and circuit boards) and classical laser marking applications.

UV laser engravers from STYLECNC are available in different power ranges, which meet customer's different laser etching requirements.

Ultraviolet laser engravers can be used to mark, etch and engraver a wide range of materials:

Almost all plastics can be engraved with Ultraviolet lasers, including ABS (Acrylonitrile Butadiene Styrene), PA (Nylon), PC (Polycarbonate), PE (Polyethylene), PP (Polypropylene), PS (Polystyrene), PLA (Polylactic Acid), PMMA (Acrylic), POM (Polyoxymethylene & Acetal), and PVC (Polyvinyl Chloride).

Metals can be engraved and marked with Ultraviolet lasers, but it does not have the same effect as a fiber laser marking machine. Fiber laser generators can etch deep and clear effects on metal surfaces, while UV laser generators have problems when etching coated metals or reflective metals like copper. Metal materials that can be engraved by Ultraviolet lasers include Titanium, Gold, Silver, Stainless Steel, Chrome, Platinum, Aluminium, and Brass.

Wood materials such as Plywood, MDF, Fibreboard, Walnut, Ash, Oak, Birch, Mahogany, Cherry, Maple, Pine, Larch, Cedar, Spruce, and Fir can also be etched and marked with Ultraviolet lasers.

In addition, it can also mark garments rich in synthetic fibers. Leather, glass, crystal, paperboard, and cardboard are of course no exception.

Features & Advantages

UV laser marking is a cold working method. Its marking accuracy is high in visible light and infrared band lasers. Under the same conditions, the shorter the wavelength, the smaller the focused spot (the shorter the wavelength, the single photon The greater the energy will be). Visible light and infrared band lasers rely on thermal effects to mark on evaporated materials, but ultraviolet laser can directly break a chemical bond of the material, which is the separation of molecules from the object. The heat-affected area of processing is relatively small, and it can be used for very fine and special materials. Because this marking method has almost no thermal effect, it is also known as laser cold marking.

Compared with common laser marking machines, UV laser marking machine has extremely small spot, which makes the material heated area smaller, less susceptible to thermal deformation, lower power, and more precise marking. It is suitable for ultra-fine marking environment, food and medicine packaging, glass division, electronic components, metal jewelry marking, etc. It can be said that the Ultraviolet laser marking system can mark and code almost all materials, and the marking effect is better than that of other laser machines. Although its price is a bit expensive, but the practicality is very good.

1. The beam quality is high, the spot is very small, and it can realize ultra-fine marking;

3. Fine marking: The diameter of the laser spot is greatly affected by the wavelength of the light. The UV wavelength (355 nm) is 1/3 of the basic wavelength (1064 nm), so the spot size can be reduced, and marking can also be carried out in a limited space;

3. Galvo-type high-precision marking head, with fine marking effect and repeatable processing;

4. High-precision and meticulous spot to ensure perfect marking results;

5. The marking process is non-contact, and the marking effect is permanent;

6. Ultraviolet laser marking machines have a wide range of applications;

7. The heat-affected area is very small, there will be no thermal effect, and the material will not deform or burn, so it can avoid damage to the processed material;

8. The marking speed is fast and the efficiency is high. It has high average power and high repetition frequency, so the marking speed is faster, which can effectively improve the production efficiency;

9. The whole machine has stable performance, small size and low power consumption;

10. It is more suitable for processing materials with large thermal radiation response;

11. It can cooperate with the production line, automatic loading and unloading, automatic feeding and discharging;

12. It is suitable for marking on most metal and non-metal materials.
