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 .
