UV laser marking machine

In the field of modern precision processing, because the traditional laser marking machine uses laser thermal processing technology, there is a limited development in fineness.
 Under this background, the ultraviolet laser marking machine has become the darling of the new era. It uses a kind of cold processing technology, the processing process is called
 "photoetching" effect, "cold processing" has a very high load energy (ultraviolet) photons, which can break the chemical bond in the material or the surrounding medium to make 
the material non-thermal The process is destroyed, the inner layer and nearby areas do not produce heating or thermal deformation, etc. The final processed material has smooth edges
 and extremely low carbonization, so the fineness and thermal influence are minimized, which is a major aspect of laser technology.

The working principle of UV laser marking machine:

The reaction mechanism of ultraviolet laser processing is realized by photochemical ablation, that is, relying on laser energy to break the bonds between atoms or molecules, making 
them vaporize and evaporate into small molecules. The focused spot is extremely small, and the processing heat-affected zone is minimal, so it can be used for ultra-fine marking and 
special material marking.

Application range:

Nowadays, with the rapid development of laser equipment and the increase in the power of UV laser marking machines, UV laser marking machines have been used in the ultra-fine processing 
high-end market, iPhone, cosmetics, medicine, food and other polymer materials packaging bottle surface Marking; marking and scribing of flexible PCB boards; micro-hole and blind hole 
processing of silicon wafers; LCD liquid crystal glass, glassware surface, metal surface coating, plastic buttons, electronic components, gifts, communication equipment, building materials,
 etc. Areas.


Many of the common signs in our daily lives, such as metal or non-metallic marks, text and patterns, BMW logos, mobile phone buttons, etc., are all marked by UV laser marking machines. 
The principle is that the laser light energy of the ultraviolet laser marking machine evaporates the surface layer of the target substance to expose the deep layer of the substance,
 thereby "carving" the required pattern text. In simple terms, it uses the laser beam to print permanent marks on the surface of various substances. 

Most materials can absorb ultraviolet lasers, such as consumer electronics, mobile phone parts, LCD screen engraving two-dimensional codes and trademarks, ceramics, sapphire sheets, 
capacitive touch screen ITO etching, etc., can all work with ultraviolet laser marking machines.

For glass, it can only be marked with a UV laser marking machine. In general, the application range of UV laser marking machine is relatively wide.
