G3-UV Laser Marking Machine 3W/5W

How Does UV Laser Marking Machine Work?

The principle of UV laser marking system is similar to the most common laser marking machines, which use laser beams to make permanent marks on the surface of various materials. The effect of marking is to directly break the molecular chain of the substance through the short-wave laser (different from the evaporation of the surface substance produced by the long-wave laser to expose the deep substance) to reveal the pattern and text to be etched.

Ultraviolet laser marking is a type of cold engraving method. The engraving process is called the "photoetching" effect. "cold processing" has a very high load of energy (ultraviolet) photons, which can break the chemical bond in the material (especially organic material) or the surrounding medium. To cause the material to undergo non thermal process damage. There is no heating or thermal deformation on the inner layer and nearby areas of the processed surface. The high-energy molecules of ultraviolet photons directly detach the molecules on the metal or non-metal materials that need to be processed. However, this detachment causes the molecules to separate from the material. This way of working does not generate heat, because it does not generate heat. As a result, the method of UV laser processing has become cold processing, which is the source of the difference from traditional fiber laser marking systems.

Why Choose UV Laser Marking Machine for Plastic, Silicon, Glass, Ceramic:

The UV laser marking machine is based on its unique low-power laser beam, so it can perform ultra-fine marking and special material marking. It is the first choice for customers who have higher requirements for marking effects. It is especially suitable for the high-end market of ultra-fine processing, with fine effects and clear and firm markings. Ultraviolet laser marking machine has high beam quality and small focused spot, which makes marking finer and higher definition; and the heat-affected area is small, no thermal effect is generated, and the deformation or scorching of the processed material is avoided. The applicable materials are particularly wide, which solves the problems of insufficient detail and poor effect of fiber laser marking for many materials. The marking speed is fast and the efficiency is high. The function of online flying marking can be realized on the assembly line.

Features & Advantages of Desktop UV Laser Marking System for Plastic, Silicon, Glass, Ceramic

1. UV laser marking machine adopts 355nm pumped UV laser device, so as to get smaller diameter of focusing spot and fine marking effect. 2. The metal absorb UV higher than infrared and therefore more suitable for UV laser marker marking on metal and glass materials compared with infrared pump machine. 3. Narrower pulse width of UV laser makes a shorter time of processing on materials, thus the materials avoid being deformed or burnt due to thermal. 4. With smaller heat affected area and more beautiful marking effect, our products UV laser marking system can meet customer with higher marking requirements. 5. The UV laser machine is equipped with safety shield, which can effectively isolate the purple radiation, to ensure the safety of UV laser marker operators. 6. UV laser machine is equipped with a professional water cooling machine, air cooled water circulation cooling, with water-cooled high efficiency and air-cooled small size. 7. Low energy consumption, environmentally friendly, no consumables. Little affect area, no heat effect, without material burned problem.
