Laser Marking Technology for Automotive


Laser marking is the use of polarized light beam produced by the face-mirror laser to focus on the focusing device producing exceptional energy rays. The laser beam at the concentration point of 0.3-0.5 mm in diameter, can be obtained from 106-108 W / cm light intensity, close to the workpiece, workpiece surface to achieve liquid-bound physical change.


Normal laser marking process is mainly used for roof marking, noise reduction and can adapt to new body structure. There are so many automotive companies that already use Laser marking on automotive components. The main European carmaker used for most of the laser marking roofs. Currently, Volkswagen has been on Audi A6, Audi A4, Golf, Passat and other roofs using this technology, BMW 5 series, Opel Vectra and the production of Volvo Sweden cars on some laser marking models are in a hurry. In China, Shanghai Volkswagen has been used in many laser models of marking techniques for home roof and outer edge of panel panels, such as Passat, Touran; Regal new Shanghai GM, LaCrosse platform also used laser marking process.
