Analysis of current situation of laser marking machine industry in China


  Laser marking is the largest laser processing equipment industry in our country. It is the most widely used, the equipment is also the most, and the manufacturers are particularly large. Almost all laser companies produce or assemble laser marking machines.

  Laser marking industry chain including laser marking and marking technology two aspects, relatively speaking, the marking process than cutting and welding should be simple, but if it is ultraviolet laser marking and laser color marking is not easy, marking mechanism is more complex. Usually marking is engraving depth or thermal effect, and the color material contrast, and more physical change.
China's manufacturing marking machine system technology is quite mature, and there have been many signs of division of labor, and the formation of various marking machine manufacturers supporting the professional upstream parts company, such as laser power supply company specializing in the production of semiconductor laser lamp power supply, power supply, Q switching power supply, the company production of optical lenses, beam expander, field mirror, mirror, motor company specializing in the production of galvanometer driver card, software company specializing in the production of laser marking software and control interface, machine processing company specializing in the production of cabinets, precision machinery parts, also have to provide a full set of marking machine accessories one-stop professional matching accessories company.
There are many kinds of laser used in the marking machine. The gas laser includes pulse CO2 laser, CW CO2 laser, excimer laser, etc., but the continuous wave CO2 laser is the main one.
Our own production of laser are basically DC excitation of glass tube carbon dioxide laser, its advantage is low cost, but the beam quality and service life of all problems, but the large number of lasers used in laser medical, to meet the basic requirements of medical laser. The carbon dioxide laser pumped by radio frequency is basically imported and monopolized the domestic market with Coherent, Synrad and Universal, and the price is not low. Lamp pumped solid laser and semiconductor side pump basically to domestic based, related accessories such as lights, rods, optical lens, pump cavity, laser power supply, switching power supply, Q semiconductor laser power supply are made in China, but the acousto-optic Q switch and the pump cavity in the ceramic reflector mainly imported.
Diode end pumped laser, 1064nm laser and 532nm made in China, but the 355nm and 266nm wavelength laser mainly imported, acousto optic tunable Q laser and acousto optic modulator drive is basically dominated by imports, and in Britain, GUCCI products Monopoly in the domestic market. In addition, TEA pulsed CO2 lasers and excimer lasers are used for mask marking, but the amount is small and the climate is not formed. Fiber laser to Germany's IPG products to monopolize the domestic market.
China's industrial laser after decades of development, basically formed a relatively complete industrial system and industrial chain, the laser industry is still a sunrise industry, in the future, we should focus on the industrial chain of upstream products and technologies, such as a new type of laser and core components, development of laser technology, laser technology China came to the forefront of the world.
