Laser marking technology applied to industrial processes

Laser Marking technology as a modern method of precision machining, and corrosion, EDM, mechanical characterization, and printing traditional processing methods, compared to the unmatched advantages: 1, done by laser processing means, and no processing of the workpiece between the role of a non-contact, non-cutting force, the advantages of small heat-affected, and ensure the accuracy of the original parts. At the same time, the adaptability of the broader material, in a variety of materials can be produced very fine surface markings and very good durability. 2, the space control and laser controlled good time, the object of the processing materials, shape, size and processing environment of freedom are great, especially in the use of automated processing and special processing. And the processing is flexible, and can adapt to the individual laboratories for the design needs, but also meet the requirements of the industrialized mass production. 3, laser characterization fine lines can be achieved mm and micron, laser marking technology and the production of counterfeit markings are very difficult to change, the product security is extremely important. 4, laser processing systems and CNC technology can be a highly effective combination of automated processing equipment, could play all kinds of text, symbols and designs, easy-to-design software design marking, labeling changes, adapt to modern production of high-efficiency, fast-paced requirements. 5, laser processing no sources of pollution, is a clean and pollution-free environment-friendly processing technology. Laser Marking technology has been widely used in industries, for high-quality, efficient, non-polluting and low-cost production of modern processing and opened vast vistas. With the application of modern laser marking the continuous expansion of the area of the laser manufacturing equipment system of small, high efficiency, and integration of the requirements of increasingly high, the new high-efficiency fiber-optic laser technology, successful development, this will certainly have a very big impetus.

Laser Marking Technology in the application marked Aluminum

Aluminum industry Stenciling Unit on the first inkjet printing products company profiles of the markings, security processing, has the following shortcomings: 1, unable to provide permanent marker. 2, prone to hardening caused dust ink inkjet head plug, it is necessary to regularly clean pipes. 3, the high cost of operating supplies. Laser marking: Profiles on the laser jet's trademark, was well on the market, greatly reducing the number of small businesses run defense. Process: Extrusion ingot from a round white wood, white wood from the sandblasting after electrophoresis, or direct oxidation of wood, white wood powder spray directly after surface treatment, that is, electrophoresis wood, oxidized material, powder spray three wood Aluminum common market. In general, white wood with laser marking, laser at the same time the 5-, marking time for about 4-5 seconds, and again after the Road electrophoresis or oxidation processes with the formation of a watermark similar to the effect of the renminbi, to the security Objective. Not in the direct oxidation products electrophoresis wood or wood on the marking, first, because they finished after marking a surface coating damage, and affected the corrosion resistance, and second, because the laser marking process in the middle, some small factories to buy Laser Marking Machine trademark-run, the existence of the equipment before and after the procedure with the laser marking equipment at the same time as a false instrument was confiscated risks, in terms of the Southern aluminum fabrication is to raise the threshold. Powder sprayed on the line for laser marking, taking into account powder spray thick layer of the grave marker of coverage, resulting in marked unclear. Power marked increase will seriously affect the life of the semiconductor. Lengthened marking time will seriously affect productivity. To address this situation, I propose two companies solutions: Option 1, I recommended that the powder spray later YAG marking. Because the high-expansion can be seen under the microscope by semiconductor YAG laser marking machine a layer of powder no damage, which is YAG laser wavelength with the photochemical reaction from the powder layer, it just changed the color. Therefore, I recommended that the semiconductor YAG laser marking machine after playing in the powder spray, because current can be controlled in about 12 A (currently electrophoresis timber and wood of the current marking around 18 A), can greatly extend the life of semiconductor modules, can greatly reduce equipment maintenance rate, and time can be shortened in about one second, their production has increased dramatically rhythms. Option 2, I recommended that the powder spray later in the CO2 laser marking machine marking. In the high-expansion can be seen under the microscope with CO2 laser marking machine is a powder-destructive, CO2 laser wavelength of the ignition of the powder layer results, but because the laser energy can be controlled, so the depth of damage can be in the control of the profile does not affect the scope. After pitting corrosion test (in the laboratory simulation of natural acid-base corrosion), verify this conclusion. Therefore, we proposed to use CO2 in the powder spray after fight, a laser energy through the control of the coating can damage control in the acceptable range. The time can be shortened in about one second, their production has increased dramatically rhythms. 3 CO2 laser imports for the whole of sealed maintenance-free products, equipment removed from water-cooled air-cooled machine, greatly reducing equipment maintenance rate. 40 30 W and can be used 10 W imports of CO2 lasers, and greatly reduced equipment prices. Electrophoresis of the wood or wood, Marking, is also pushing the 100 W lamp-pumped, not pushing 50 W semiconductor, semiconductor laser module to resolve user environment in the life of the issue, while meeting the user more clearly marked effect of the request .

"Yin and yang face" the girls miracle recovery after laser treatment

British girls Beijipuluose face at the time of birth there is a small red characteristics of the characteristics of this rapidly expanding rapidly and has become a huge long hemangioma, the entire left side of her face all the coverage so that Mbeki was pretty face become a terrorist "yin and yang face." Fortunate is that after a long and painful after laser treatment, doctors finally removed Mbeki left the face of the huge hemangioma, she looks back to normal. After birth into a "yin and yang face" Just at the time of birth in 2001, Mbeki faces a long tiny red spots when nurses did not notice that the only common characteristics of a simple handling. But it is not thought that in the next six weeks time, the Little Red started drastic "developmental", grew up quickly extended to the entire Zuolian, Mbeki's face has become a terrible, "Yin and Yang Face ! " It is even more serious, "Birthmark" began to affect Mbeki's vision, her left eye is unable to see the outside world; In addition, "Birthmark" squeeze the Mbeki mouth, she even infants are difficult . Mbeki disease to her parents - 39-year-old supermarket manager Darren and 36-year-old real estate agent, Debbie, burning with impatience, his mother, Debbie, recalled: "She looks great terror, as if there is a alien invasion of her body the same. looked at things a little bit that destroyed her daughter's face, but I could do nothing about it. " 18 who were tortured on laser treatment Mbeki's parents immediately daughter to the hospital. After diagnosis, Mbeki suffered from "hemangioma", which is due to a vascular lesion formation in tumors. According to the doctor, if the newborn suffering from the disease first emerged largely similar to the "characteristics of" small blot. But the general "hemangioma" are benign, and rarely have such a big area like Mbeki, the proliferation of examples. Later, Mbeki has been transferred to the Bedford County Hospital more advanced professional laser out-patient treatment, where the experts also said Mbeki is that they have seen the face of the worst "hemangioma" patients. Mbeki to treatment, doctors first to Mbeki, through intravenous injection of steroid drugs to control the spread of hemangioma, at the same time save her eyesight. Subsequently, the doctor Mbeki for the first time laser surgery, she tried to remove the face of the hemangioma. Mother, Debbie, recalled: "During the operation, her wound faces are everywhere, distributed a charred flavor. See she must suffer the torment, my heart is broken." Finally resumed pretty face During the 18-month period, a total of Mbeki doctors conducted five such laser surgery. Although each treatment is extremely painful, but the good news is now Mbeki faces hemangioma have all been removed, Mbeki not only save the eyesight, her face is basically back to normal. However, Mbeki Zuolian skin is still slightly faded traces In addition, she must wear glasses, for the left eye vision correction. According to his mother, Debbie, said, a 7-year-old small Mbeki full of self-confidence, she said happily: "daughter can now finally the camera happily I can not believe that all this will progress smoothly, I would like to tell those other and we have similar unfortunate experience of families, do not give up hope, there is always the end of the dark bright.
