Analysis on the advantages and disadvantages of laser marking machine

by:J&D WATER     2020-03-24
Laser marking is using laser beam of high energy density laser beam effect on workpiece vaporizing parts appearance or attack intention of trace chemical composition to reach processing, laser marking system usually light from a laser source system cooling system, control system and the work station, etc. 1. Lamp pumped YAG laser marking machine, YAG laser is infrared spectrum wavelength of 1. 064 um solid laser, choose krypton lamp as a source of energy ( Encourage the source) ,ND:YAG( Nd: YAG laser. Nd( Nd) Is a kind of rare earths elements, YAG on behalf of yttrium aluminum garnet, crystal structure is similar to ruby) As the laser medium, announced that a particular wavelength can promote homework material yield level transition release laser, the laser energy enlarged, make up for data processing of a laser beam. Strength: offer cheaper. Defect: laser marking precision is not high; Water is large; Material to replace. 2. Semiconductor laser marking machine semiconductor back-end semiconductor pump laser marking machine marking machine is using the wavelength of 0. 808 um semiconductor laser diode ( Next to the face or face) Pumped Nd: YAG medium, restore medium happen a lot of particles under the effect of Q switch wavelength of 1. 064 um of giant pulse laser output, electro-optic conversion efficiency is high. Meantime YAG marking machine used for metal and semiconductor, IC, etc. , semiconductor compared with YAG has good stability, save electricity, don't need to change the lamp, such as strength, price is relatively high. Strengths: a. Good beam quality is relatively light pump. Side and side pump, the pump line quality precision is higher. b。 Small volume. By contrast the pump for wind cooling can do less. c。 No material defect: high quotation. 3. Optical fiber laser marking pause with produce fiber laser marking machine, laser beam quality is good, high electro-optical conversion efficiency. Strengths: beam quality is very good, the accuracy is higher, no consumables. Defects: offer the high of the semiconductor. 4. CO2 laser marking machine, CO2 laser is infrared spectrum wavelength to 10. 64 um gas laser, choose CO2 gas filling the discharge tube as the laser medium, when extensions on the electrode voltage, discharge tube in glow discharge occurs, it can make the gas molecules release laser, the laser energy enlarged, make up for data processing of a laser beam. CO2 is used for wood, acrylic, leather and other non-metallic marking. Strengths: air-cooled, no consumables. The quote moderate defect: not on the metal materials. Laser marking equipment recommended: preferential deals offer 4007001618 【 Optical fiber laser marking equipment 】 Mainly used for metal and non-metallic laser marking part USES, tags and beautiful, fast, no material; 【 CO2 laser marking equipment 】 Non-metallic products used for the laser marking purposes; 【 Uv laser marking equipment 】 Adopt import uv laser, it is mainly used for metal and non-metallic products fine marking purposes; 【 Metal laser marking equipment 】 Based on customer specific products, production line, the demand for design and production and customer demand, customized models. 【 Semiconductor laser marking machine 】 Stable performance, price moderate 【 Green laser marking machine 】 High prices, product customization is given priority to YAG laser marking machine 】 Metal, plastic and other products used for moderate price more laser marking equipment laser marking machines, laser marking
