Understanding UV Laser Marking on Metal and Non-Metal Materials

The reason why UV laser marking machines can mark both metal and non-metal materials is as follows:

 

Firstly, UV laser marking machines utilize a laser with a relatively short wavelength, typically ranging from 300 to 400 nanometers. This wavelength range allows the laser to interact effectively with various materials, penetrating and interacting with their surfaces.

Secondly, UV lasers possess high energy density, enabling precise marking in small areas. They can rapidly oxidize or evaporate material on the surface, creating clear marks, regardless of whether it's metal or non-metal material.

Furthermore, the laser beam from a UV laser marking machine has excellent absorption capabilities for many materials. This characteristic leads to rapid heating during the marking process, resulting in visible and distinct marks. This capability enables UV laser marking machines to achieve high-quality marks on both metal and non-metal materials.

In summary, the wavelength characteristics and high energy density of UV lasers allow UV laser marking machines to achieve precise and efficient marking on both metal and non-metal materials.
