What are the advantages of carbon dioxide laser marking machine?

The common ultraviolet laser engraving machine on the market or called ultraviolet laser laser engraving machine and UV ultraviolet laser marking machine belong to a kind of ultraviolet laser marking machine series, so the principle is similar to the ultraviolet laser marking machine. It uses a laser beam to permanently mark the surface of various substances. The effect of marking is to expose the deep material through the evaporation of the surface material, or to 'engrave' traces through the chemical and physical changes of the surface material caused by light energy, or to burn off part of the material through light energy, showing the required etching. pattern, text.

Ultraviolet laser marking machine

Ultraviolet laser marking machine is a cold working method, and its processing accuracy is high In visible light and infrared wavelengths, and under the same conditions, the shorter the wavelength, the smaller the focused spot (the shorter the wavelength, the greater the energy of a single photon). Visible light and infrared band lasers rely on thermal effects to mark on evaporated materials, but ultraviolet light can directly break a chemical bond of the material, and the molecules are separated from the object. The heat-affected area of u200bu200bprocessing is relatively small, and very fine and special materials can be marked. mark. Because this way of marking has little thermal influence, indexing is also known as laser cold work marking.

Ultraviolet laser marking machine shows extremely high absorption rate when applied to resin and copper, and also has appropriate absorption rate when processing glass. Only expensive excimer lasers (wavelength 248nm) get better overall absorption when processing these primary materials. This material difference makes UV lasers the best choice for a variety of PCB material applications in many industrial fields, from the production of the most basic circuit boards, circuit wiring, to advanced processes such as the production of pocket-sized embedded chips. ?

UV laser marking machine

Compared with ordinary laser marking machines, the UV laser marking machine has a very small spot , so that the heating area of u200bu200bthe material is smaller, and it is not easy to be deformed by heat; the power is lower; the marking is more precise, and it is suitable for ultra-fine marking environment, food and medicine packaging, glass division, electronic components, metal jewelry marking, etc. It can be said that the UV laser marking machine can mark and code almost all materials, and the marking effect of the UV laser marking machine is better than that of other laser machines. Ultraviolet laser is a kind of cold light laser, and the absorption rate of various materials for ultraviolet light is relatively high, and the thermal effect of ultraviolet laser marking is small and will not damage the material itself, so the range that can be marked by ultraviolet marking It is also very extensive, but its price is also relatively expensive. It can be said that the practicality of the UV laser marking machine is very good.

After the successful research of the UV laser marking machine, it has played a supportive role in the fields of energy and materials, and has also played a significant role in the country's total economic output. It has a great indirect effect, and has solved many important scientific problems, which plays a very decisive role in the future development. 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.
