Laser marking technology is one of the biggest applications of laser processing. Laser marking is a marking method that makes use of the high energy density laser to irradiate the work piece locally, so as to make the surface material vaporize or change the color, leave a permanent mark.Laser marking can mark a variety of words, symbols and patterns, the size of the characters can range from millimeters to microns, which has special significance for the product anti-forgery tag.
The basic principle of laser marking is that the laser generator generates high-energy continuous laser beam. The focused laser beam acts on the printing material to melt and even vaporize the surface material instantaneously. So that the required laser image can be marked by controlling the path of the laser on the surface of the material .
Laser marking is characterized by non-contact processing, It can mark almost all the parts(such as the piston, piston rings, valves, seats, hardware tools, sanitary ware, electronic components, etc.)The mark is stand wear and tear,the technology is simple and auto-operation is easy, and the marked part is deformed little.
I get many information from this website and i think it will be helpful to improve my content at laser marking technology
Thank you so much for providing these information to us. I’ll be in contact with laser marking technology
This blog is really very helpful for us to get information. I think that it should be helpful for laser marking technology
