Today, there are many industries and products for which laser marking on metal is suitable. Laser engraving or laser labeling is a very good way of ensuring product traceability. Information can be engraved on different metal logos and labels with a laser. Some ceramics and plastics can also be labeled. 

Laser markings highlight industrial products of all kinds. Accurate and economical laser marking on stainless steel precisely attaches a simple and complex content even on titanium or aluminum. Integrated laser checks check-marked characters such as 1D/2D codes, serial numbers, alphanumeric characters, logos, or diagrams directly after marking.

Laser Marking on Metals Offers Many Advantages:

The power density of the laser beam is so high that the material melts and partially evaporates during processing. An indentation is created in the material, i.e. an engraving. In metals, the molten base material interacts with the oxygen in the air. For laser engraving on metal, the energy should be at least 0.4 kJ/cm².

In the metal industry and automotive industry, laser marking is commonly used to mark wear-resistant and anti-factor labels with laser engraving on stainless steel or to create aluminum. 

Various methods are suitable for laser markings, such as annealing or laser marking of aluminum and titanium. The provision depends on the specific application of the industrial sectors concerned.

In annealing, the metal is heated beneath its surface. This provokes a change in the color of the material. With different temperatures correspondingly different color tones are produced. This type of laser marking is suitable for all metals that contain iron, ie steel, stainless steel, chrome, or titanium.
