Ultraviolet laser marking machine and fiber laser marking machine are a simple division of the mainstream market according to the light source. The product materials and industries used by each laser marking machine are different.
Analyze the difference between UV laser marking machine and fiber laser marking machine from three aspects
Core components:
1. Fiber laser marking machine: The wavelength of 1064nm is used. Generally, the shorter the wavelength, the smaller the laser spot, the higher the precision, the smaller the heat-affected zone formed during processing, and the more exquisite the processing effect.
2. Ultraviolet laser marking machine: Using a ultraviolet laser with a wavelength of 355nm, the focusing spot of the 355 ultraviolet light is extremely small, which can greatly reduce the mechanical deformation of the material and has a small thermal influence on processing.
Processing method
The processing method of ultraviolet laser marking machine is different from other laser marking equipment. Generally, for fiber laser marking machine, it is used for physical marking method of laser, while ultraviolet laser marking machine uses chemical processing method. , It is mainly processed by photochemical reaction. The difference between these two different processing methods is that the laser physical processing method is mainly processed on the surface of the product and material, while the laser chemical processing method can use the laser to penetrate deep into the product material. Processed in-house.
Application areas
Ultraviolet laser marking: mainly used in consumer electronics, mobile phone parts, LCD screen engraving two-dimensional code and trademark ceramics, sapphire, glass and other metal or non-metal products
Fiber laser marking machine: widely used in electronic parts, various auto parts, home appliances, hardware tools, mold jewelry, tobacco and military affairs and many other fields of graphics and text marking.
From the comparison, we can see that the UV laser marking machine and the fiber laser marking machine have irreplaceable roles in various fields, and for the manufacturing industry, you can choose the equipment that suits your needs through the characteristics of the two.
