Laser marking non-contact processing, can be in any special surface marking, the work piece will not deformation and produce internal stress, suitable for metal, plastic, glass, ceramics, wood, leather and other materials marking.Laser marking is a new processing technology developed after laser welding, laser heat treatment, laser cutting, laser drilling and other application technologies. It is one of the largest application fields of laser processing.In recent years, with the improvement of the reliability and practicability of laser, the rapid development of computer technology and the improvement of optical devices, laser marking technology has developed rapidly.
Laser marking produces a very fine laser beam, the spot of light can be the object surface material point by point removal, its advanced is that the marking process is non-contact processing, does not produce mechanical extrusion or mechanical stress, so it will not damage the processed goods;Due to the small size, small heat affected area and fine processing after laser focusing, some processes that cannot be achieved by conventional methods can be completed.Laser can mark what kind of information, only related to the content of the design in the computer, as long as the drawings designed in the computer can be identified by the marking system, the marking machine can accurately restore the design information on the product, do not need to add additional equipment and materials.Laser marking these characteristics, so that it and printing, ink jet code, corrosion, stamping, mechanical engraving and other traditional processing methods have unparalleled advantages.
With laser processing means, there is no processing, the action of forces between artifacts and has no contact, no cutting force, small heat affected, the advantages of guarantee the original precision of the work piece, the processing of the object’s shape, size, and processing conditions of degrees of freedom are big, especially suitable for automation and special surface machining, and durability is very good.
Material applicable range is wide, can be in metal, plastic, pottery and porcelain, glass, paper, leather wait for the material with different kind or different hardness to hit mark.
High machining accuracy, laser beam can be very thin on the material surface, the narrowest line width can reach 0.05mm, can meet the needs of printing a lot of data on a very small piece of work.Laser marking technology produced by the mark clear, durable, beautiful, imitation and change are very difficult to the product anti-counterfeiting is extremely important.Compared with printing or jet marking, laser marking has stronger market competitiveness.
