Principle of UV laser marking machine

UV laser marking machine belongs to a series of laser marking machines, but it is developed by using a 355nm ultraviolet laser. The UV laser marking machine uses a third-order intracavity frequency doubling technology. Compared with infrared lasers, the 355 ultraviolet light has a very small focal spot. It can greatly reduce the mechanical deformation of the material and the processing heat effect is small, because the UV laser marking machine is mainly used for ultra-fine marking and engraving, and the UV laser marking machine is particularly suitable for marking food and medical packaging materials, Micro-perforation, high-speed division of glass materials, and complex pattern cutting of silicon wafers.

What is the principle of the UV laser marking machine?

UV laser marking machine is a series of laser marking machines, so the principle is similar to that of a laser marking machine. They all use a laser beam to make permanent marks on the surface of various materials. The marking effect of the UV laser marking machine is to directly break the molecular chain of the substance through the short-wavelength laser (different from the evaporation of the surface substance produced by the long-wave laser to expose the deep substance) to show the pattern and text to be etched.

What are the outstanding advantages of UV laser marking machines?

The UV laser marking machine can perform ultra-fine marking and special material marking due to its very small focus spot and small processing heat-affected zone. It is the first choice for customers who have higher requirements for marking effects. In addition to copper materials, UV laser marking machines have a wider range of materials suitable for processing.

The UV laser marking machine not only has good beam quality, but also has a smaller focused spot, which can achieve ultra-fine marking; the UV laser marking machine has a wider application range; the UV laser marking machine has a very small heat-affected area, and will not produce thermal effects.

Material burning problem; UV laser marking machine has fast marking speed and high efficiency; the whole machine has stable performance, small size, low power consumption, and other advantages.

The difference between water cooling and air cooling of UV laser marking machine

The cooling equipment of the UV laser marking machine is water-cooled or air-cooled. It mainly depends on the power of the UV laser marking machine itself. Water cooling and air cooling have the same function, and they both play a cooling role to ensure the normal operation of the UV laser marking machine.

Dongguan Mactron Technology Co., Ltd. has developed a variety of UV laser marking machines and conducted a lot of tests before leaving the factory to ensure quality. These UV laser marking machines are not only of good quality but also have have a long lifetime. If you are in the UV laser marking machine, you can consider using our cost-effective products.
