For example, if I run a 20 watt fiber laser at 50% power setting in my software, I am running at approx. In some cases a dark anneal can work, but surface irregularities can cause reduced readability. We have found that lower powered, faster pulsing lasers yield the best results. 0000010705 00000 n Gold can be very easy to mark, requiring little power to get a good, contrasting anneal. Some plastics and polymers can be lightly etched or engraved, but consistency is always a concern. Rubber See what happens of XTLASER, connect with us you will know more about us. Use both laser sources in a single job without having to manually change the laser source, lenses or focus. A white color is most common when polishing or annealing carbide and the contrast is extremely good. These setting are optimum for around 150-300dpi. Send the field at low power (about 10-20 %), maximum speed and 500 dpi to the laser. 34 30 %PDF-1.5 %���� 0000003405 00000 n The most common technique in plastic and polymer marking is color changing. 34 0 obj <> endobj Chrome Tungsten, being slightly lighter in color, requires an annealed mark to achieve proper contrast. Fiber lasers are incredibly expensive (the MOST expensive) but require much less maintenance and are much more durable and efficient with its power usage. The annealed marking will be black and the polished marking is typically white. Another popular segment for these substrates is wedding bands for men. Care must be taken in order to prevent it from becoming pierced or damaged, which would expose the underlying metallic surface. In laser material, very soon after we 'pump' the electron to a higher state, it slides down to a slightly lower meta-stable state. 0000005338 00000 n There are many types of coatings used to harden or protect metals from corrosive elements. Each and every XT Laser series is capable of marking on nickel and the ideal system for your application depends on your marking requirements.
