Laser marking works on various metals, plastics, paints and laminates, on foils, woods, glass, leather, textiles, meat, paper or cardboard. There are three basic principles:
Advantages include the extreme durability and brilliance of the markings, as well as the flexibility of the lettering, even at speeds in excess of 1,000 characters a second. On top of that, forgery-proof markings are in no way affected by mechanical stresses on the component. Medical technology, air and space travel, the automotive and food sectors as well as manufacturers of electronics and semiconductors among other industries use laser marking in the application of continuous part, serial and batch numbers, machine-readable codes, and dates, or of lettering, company logos or decorations, both on labels or directly onto products.
Industrial application of lasers isn’t limited to metal, glass and semiconductors. Laser technology also gains ground in the processing of textiles, leather, paper and wood.
