How to choose laser marking machine？

     1. According to laser Categories
     1) laser Categories
     Laser divided into solid-state laser (Yttrium Aluminum Garnet YAG and YVO4 YVO4), gas lasers (He-Ne laser, CO2 laser) two categories.
     ① carbon dioxide (CO2) laser marking machines, as the activation of CO2 by the media, to launch the 10600 nm infrared region of the light waves. Such lasers have two different forms.
     a. Pulsed laser. Use of mask approach to short-pulse laser tag or by energy generated. However, because of the different needs of different markers of the block, the tag changes require a longer time.
     b. Continuous laser. T-use forms, only one-level, technical Yaoqiubugao, low cost, simple equipment, but exports of high-energy, high efficiency, widely used in plastics laser tag printing.
     ② YAG laser marking machine. Activation of the media is solid, near infrared laser to launch the 1060 nm region of the light waves, a continuous, two-light pen, by changing the output of energy, can be different intensity laser beam. Marking of a coking (dark markings), foam (light-colored marker) and ablation (engraving tag), marking an excellent quality.
     ③ excimer laser marking machine. Capable of launching a range of ultraviolet light (100 ~ 400 nm), activated from the media helium, argon, krypton, neon gas and chlorine, fluorine, bromine, iodine, such as halogen composed of a mixture.
     2) CO2 laser marking and solid YAG laser marking of the distinction
     ① application of different materials. Because of their different wavelength, carbon dioxide laser marking machine could only be used for non-metallic materials marking; YAG laser marking machines for both non-metallic materials marking, but also can be used for marking of metal materials.
     ② supplies used by different. CO2 laser marking machine is the main supplies of gas mixture and laser, and germanium lens is also wearing parts, prices more expensive; YAG laser marking machine supplies is the main pumping lights (xenon use of pulsed laser lights, continuous laser The use of krypton lights), low prices.

     2. According to the form of laser output classification
     Laser Marking machines under different forms of laser output can be divided into solid cover model, the gas cover model, mechanical scanning, galvanometer scanning and other types.

     3. Laser Marking Machine Selection
     Laser Marking Machine Selection is based on standard products and India need the material, production and decided to tag area, following the principle of selection.
     1) solid ON mode laser marking machine
     Applicable to non-metallic materials, marking ￠7 mm in the area of the cylinder, the mass production of products, such as electronic components, and so on.
     2) Cover model gas laser marking machine
     Applicable to non-metallic materials, marking ￠20 mm in the area of the cylinder, the mass production of products, such as electronic components, plastic bottles, alcoholic drinks and tobacco and food containers and other packaging.
     3) mechanical scanning laser marking machine
     Apply to a single marker in the area of 80mm×100mm range, single-class production for thousands of products.
     4) galvanometer scanning laser marking machine
     Apply to a single marker in the area of the cylindrical ￠300 mm, single-class production of tens of thousands of products.
