Three characteristics of UV laser sources

Flying laser marking machines frequently appear in major manufacturers and are favored by more and more manufacturers. So, why has the UV flying laser marking machine become the choice of various manufacturing companies? Today, it will be explained from three aspects

01. Cold working

Ultraviolet laser processing technology is characteristic of material (metal and non-metal) cutting, welding, surface treatment, punching and micromachining. The interaction of UV laser light with matter is called photochemical melting. When a material is irradiated by a laser and absorbs pulses of peak power, it causes a thin layer of internal bonds on the material's surface to break, and the resulting molecular fragments diffuse into the plasma. The plasma takes away excess energy from the material while diffusing outward, which is the cold working of the UV flying laser marking machine.

This cold working, because it is not hot corrosion, has no "thermal damage", which interrupts the cold peeling of chemical bonds, so there is no heating or thermal deformation to the surface of the processed material. Processed material with smooth edges

This non-damaging property makes the UV flying laser marking machine more widely used than the fiber flying laser marking machine and CO2 flying laser marking machine, and its advantage lies in the coding of light and thin materials.

02. Meticulous coding

In the flying laser marking machine, the wavelength of the ultraviolet flying laser marking machine is 355nm, and the wavelength of the fiber flying laser marking machine is 1064nm. Compared with fiber flying laser marking machine and CO2 flying laser marking machine, the wavelength of UV flying laser marking machine is shorter.

Compared with the long-wavelength laser, the short-wavelength laser can obtain a smaller focus point, which is very practical in ordinary processing. Because the ultraviolet laser has the characteristics of short wavelength, small focus point, small heat-affected area, flexible and convenient processing, etc.

The optical fiber flying laser marking machine and the CO2 flying laser marking machine will cause different degrees of damage to the surface of the processed material, so the fineness of the inkjet printer is lower than that of the ultraviolet flying laser marking machine.

03. No consumables, low cost,

Before the advent of flying laser marking machines, the traditional coding method used ink jet printing, which made the usage of ink consumables large and the cost of marking and coding high. With the popularity of flying laser marking machines, the inkjet printers used in many industries in the past have been gradually updated to flying laser marking machines.

The UV flying laser marking machine adopts the principle of breaking the chemical bond of the material by the UV laser beam for identification, and there are no consumables in daily operation, which greatly reduces the coding cost of the enterprise.

Of course, the UV flying laser marking machine has the advantages of flexible installation, simple operation, convenient use, and convenient maintenance of modular structure. It is these advantages that allow it to stand out and be favored by many inkjet printers
