In machine construction high quantities of metal parts need to be marked with UIDs, barcodes or 2D-codes to ensure traceability. Serial numbers, time stamps and company logos are also often required. The marking should be resistant and withstand mechanical stress and weather influence. For a large number of components or workpieces marking times are critical and a fast method like laser marking is ideal for the task. Depending on the material the suitable marking processes can be annealing, polishing and deep engraving. For example, stainless steel can be laser marked through annealing without leaving a tangible depression on the surface. From soft metals like aluminum over steel to very hard alloys, a broad range of metals can be marked with Trotec laser marking systems.
