The advantages of UV laser in marking and cutting are incomparable with other laser equipment, engraving and micro-processing of special materials. UV laser markers are durable and non-erasable. As long as the surface of the object is not severely damaged, the marking contents will not be damaged. While marking, the object itself will not be damaged due to non-contact marking.

Ultraviolet laser marking machine fine laser engraving show

Ultraviolet laser marking machine laser engraving principle:

UV laser marking machine uses a cold working process called "photoresist" effect, "cold working" has high load energy (ultraviolet) photons can break chemical bonds in the material or the surrounding medium, therefore, the material is destroyed by a non-thermal process, the inner layer and nearby areas will not be heated or thermally deformed. The processed material has smooth edges, low carbonization, and reduced fineness and thermal shock to a very low level, which is a major leap in laser technology. Ultraviolet laser marking machines are currently used in the field of modern fine processing, due to the traditional laser marking The machine adopts laser thermal processing technology, and the development of precision is limited.

In this context, UV laser marking machine has become the darling of the new era. Laser technology is an important scientific research technology in modern molecular structure. Ultraviolet laser is a powerful technical means to study various molecular structures, and has been widely used in marking applications in high-tech industries such as glass, crystal, and photovoltaics. At present, the laser marking machines on the market mainly include CO2 laser marking machines, semiconductor laser marking machines, fiber laser marking machines and ultraviolet laser marking machines. At present, the UV marking machine is mainly used in some occasions that require higher precision and higher precision. It can be said that it is a small expert in fine laser engraving.

Laser Ultraviolet laser uses short-wave wavelength, and the focusing spot is small. It can effectively reduce the material deformation of the workpiece during processing, and the processing thermal shock is small. With the continuous maturity of UV laser technology, processing technology has been widely used and promoted. Currently, the mainstream marking materials for UV lasers on the market are plastics, glass, ceramics and metals. 3W, 5W, 10W, 20W UV lasers can be configured according to customer requirements.
