Plastic buttons laser engraving machine, Feng Rui laser, laser engraving teacher recruitment 2014

Feng Rui laser engraving laser processing applications in the field of analysis, CO2 laser cutting and welding applications with the widest respectively accounted for 70% and 20%, the surface treatment is less than 10%. The application is based on YAG laser welding, marking (50%) and cutting (15%) dominated. CO2 lasers in the United States and Europe accounted for 70% to 80%. China's laser processing mainly to cut 10%, of which more than 98% of the CO2 laser power in the range 1.5kW ~ 2kW, and heat treatment based about 15%, most of the laser processing of automobile engines cylinder liners. The economics of the technology and the social benefits are very high, so there is great market prospects. The role and type of laser marking additives: laser marking additives can alter the spectral absorption characteristics of plastics, especially for special plastic does not absorb the laser light, the proper use of laser marking additive may be adapted to laser marking, and the quality can be comparable with the normal mark. The main function of the function ① laser marking additive laser marking additive absorbing the laser energy is, the laser beam is converted into heat energy, heat generation effect on the plastic, carbonation, evaporation and chemical reaction. ② laser marking additive additive products for different varieties of lasers have many varieties, such as for carbon dioxide laser marking additives, deep on the different chemical properties of plastics, light laser marking on a dark background and light background Color laser marked with different varieties. Another example is Mark-lt laser marking pigment is designed for YAG laser marking machine designed plastic additives, suitable for PE, PP, GPPS, HIPS, ABS, PET, PBT, nylon, epoxy resin, ABS / PC, PC plastic laser marking printing.
