Difference between ultraviolet laser marking machine and optical fiber marking machine

With the development of the laser industry in recent years, the technology of the laser marking machine has become more and more mature, and the application has become more and more extensive. There are many application examples in various materials such as metal and non-metal. So today, Yunke will introduce to you the differences between the common UV laser marking machine and the fiber laser marking machine in the market, and analyze their advantages. Which is better!

1.Different lasers
（1）The ultraviolet laser marking machine uses an ultraviolet laser with a wavelength of 355nm;
（2）The fiber laser marking machine uses a fiber laser with a wavelength of 1064nm;
（3）In general, the shorter the wavelength, the smaller the focus spot, the higher the accuracy, and the smaller the heat affected zone.

2.Different processing principles
（1）The ultraviolet laser processing process is called “photo etching” effect. The (ultraviolet) photons with high load energy can break the molecular chain in the material or the surrounding medium, and do not produce heating or thermal deformation on the inner layer and the surrounding area of the processed surface. It is very suitable for fine processing.
（2）Fiber laser marking machine uses laser beam to make permanent marks on the surface of various materials. The deep layer material is exposed through evaporation of the surface layer material, or the physical change of the surface layer material is caused by light energy to “carve” a trace, or the part of the material is burned by light energy to display the pattern, text, bar code and other types of graphics to be etched.

3.Different application fields

（Medical equipment UV laser marking machine）

UV laser marking machine: it is especially suitable for the high-end market of ultra-fine processing, and the surface marking of special polymer materials such as medical appliances, cosmetics and medicine bottles. For example, various signs of medical hypotube,Menlaser provide laser cut hypotube,hypotube laser cutting,laser cutting hypotubes

（Medical equipment optical fiber laser marking machine）

Fiber laser marking machine: basically suitable for laser marking of various metal surfaces. Due to the heat generated by its beam, it is not suitable for high-precision marking of special materials.

Advantages of UV laser marking machine and optical fiber marking machine

Both have their own advantages in different fields.Advantages of UV laser marking machine: it can carry out ultra-fine processing and special material processing, low power and stable performance.The advantages of optical fiber marking machine are long service life and low maintenance cost.
The specific selection should be determined according to the specific use scenarios and the needs of the processed products.
