Lines and 2D codes, such as a serial number and QR codes, are already used in most industries, such as (e.g. the automotive industry, medical technology, or electronics industry), in order to make products or individual parts traceable. The codes (such as a datamatrix code or bar code) contain information regarding the parts properties, production data, batch numbers and much more. Such component marking must be readable in a simple manner and partially also electronically with a barcode reader and have a lasting durability. Here, laser marking proves to be a flexible and universal tool for a wide variety of materials, shapes and sizes as well as the processing of dynamic and changing data. Plastics marking as well as metal engravings are done at the highest speed and with absolute precision, while wear is minimal.
