LASER LABELLING OF METAL

Metal laser marking with EcoMark

Whether in the automotive sector, medical technology, mechanical engineering, electrical engineering or sheet metal forming: product branding and coding are required to enable the traceability or saving of information. Data matrix codes for quality assurance, or functional labelling with information about the product characteristics, such as size or radius, can also be applied quickly and durably with a laser.

Different laser options

Branding by laser can be applied to the entire spectrum of metals. Laser engraving or laser labelling can be carried out on hard metals such as iron or steel in just as high quality and with as much precision as they can on soft metals such as aluminium or copper. This is possible due to the variety of laser labelling options for metals. Robust laser engraving, which leads to a clearly recognisable and noticeable indentation via melting and evaporation of the metal, is ideal for branding materials which have to withstand mechanical stresses. In contrast to this, annealing branding is used in particular in the medical field and in areas requiring strict hygiene, as local heating of the metal creates a coloured oxide layer. The surface remains even, thereby preventing the accumulation of germs. The removal of the layer of material, in which the coating and not the primary metal material is laser marked, also creates contrasting laser labelling. All three processes are durable as they are abrasion-resistant. They are also impervious to fluids such as water and oil, as well as to the effects of heat.

Lasers can work well under the difficult, harsh and challenging production process of metalworking, as they are robust systems which are well equipped against the various environmental effects such as heat, cold, moisture and movement.
