Laser Marking covers a broad Spectrum of surfacing Techniques including Laser Engraving, Laser Ablation (Abrasion), Laser Bonding, Hot-Branding, Foaming, Colour Changes and Annealing

OSTLING laser marking systems are extremely flexible and of high quality:

Using a highly precise laser beam, a permanent marking is applied to the most varied materials, such as metal and plastic.

With the affiliated software, there are no limits to your labelling ideas. Our laser marking systems are also exceptionally suitable for automated markings such as consecutive serial numbers, 2D codes (Data Matrix™), etc.

Typical application areas

• Tools
• Ball bearings
• Metal parts for the automotive or aviation industries
• Plastic products and components for household products
• High precision micro-encoding of medical instruments
• Decorative markings on promotional items and brand name products
  
  

These marking types are possible with marking lasers:

Engraving

A groove is etched in the component with a laser beam. The material vaporizes or melts in this process. The marking depth can be up to 50 µm.

Material abrasion

This is a special form of engraving. In the case of aluminium, an anodic coating, for example, can be removed in order to reveal the differently coloured layer beneath it.

Annealing colours

Here the heat of the laser beam and the atmospheric oxygen change the colour of the metal. There is no significant material abrasion. The laser beam penetrates max. 5 µm into the metal.

Colour changes

Marking by changing the colour can be performed with most plastics and some lacquers. Special additives ensure a high contrast colour change at the place where the laser beam makes contact.

Foaming

Due to the heat of the laser beam, the plastic is thermally disintegrated at the laser beam's point of impact. This results in gaseous decomposition products, the plastic foams.
