The working principle and application range of UV laser marking machine

The working principle and application range of UV laser marking machine
Ultraviolet laser marking machine belongs to a series of laser marking machine series, and is also a newly  laser processing technology. Because the traditional laser marking machine uses laser is a thermal processing technology, which is obtained in terms of fineness. The lifting space has a restrictive development. However, the UV laser marking machine adopts a cold processing, so the fineness and heat influence is a great leap in laser technology.

With the continuous development of the laser application industry, the innovation of various types of laser equipment is accelerating. Among them, the laser marking machine is an extremely important part of the laser technology. However, the UV laser marking machine is one of the series of laser marking machines. The product is a mature laser processing technology newly developed.

In the field of modern precision machining, the traditional laser marking machine adopts laser thermal processing technology, and the fineness has restrictive development. Under such a background, the ultraviolet laser marking machine has become the darling of the new era. It uses a cold working process called “lighting” effect, “cold processing” (ultraviolet) photons with very high load energy, which can break the chemical bonds in the material or surrounding medium, so that the material is not hot. So the fineness and heat influence are minimize, which is a large laser technology. leap. Shenzhen Shangtuo Laser has a strong focus in the field of laser marking machines, and has developed a series of standard and non-standard automated UV laser marking equipment.

The working principle of UV laser marking machine:

The reaction mechanism in ultraviolet laser processing is realize by photochemical ablation. So, that is, laser energy is using to break the bonding between atoms or molecules, so that it becomes a small molecule to vaporize and evaporate. The focusing spot is extremely small, and the processing heat affected zone is minimal. So ultra-fine marking and special material marking can be performing.

Application range:

Nowadays, with the rapid development of laser equipment and the improvement of the power of UV laser marking machine. However, UV laser marking machine applying on  the high-end market of ultra-fine processing, the surface of packaging bottles for iPhone, cosmetics, pharmaceuticals, food and other polymer materials. Marking; flexible PCB board marking, dicing; silicon wafer micro-hole, blind hole processing; LCD liquid crystal glass, glassware surface, metal surface plating, plastic buttons, electronic originals, gifts, communication equipment, building materials, etc. Fields.
