Laser coding technology guide

Laser coding is one of the most reliable, versatile and cost-efficient marking methods available.

The technology is perfect for high volumes of printing and creating easy traceability on food, drink and pharmaceutical products. A concentrated beam of light is deflected by mirrors through a lens to form characters by removing material or coating from the product or packaging. Accuracy is guaranteed, giving you 24/7 operation without the need for users to manually intervene.

Laser coding permanently changes the surface of the substrate. For example, when laser coding painted card, the very top layers of paint are removed revealing the contrasting bare card underneath. The same process on plastic changes the very chemical nature of the material, either melting it to leave a mark or causing a colour change. When laser coding on glass, the laser leaves micro cracks, scribing a permanent code without weakening the material.

For more information on laser marking technologies and for advice on selecting the right type of laser for your application, read our white paper:

Linx Fibre lasers can permanently mark on a wide range of materials, including metal, rubber, plastic, and packaging foils. The very fine spot size creates excellent quality codes and makes Linx Fibre lasers ideal for marking very small components, or large amounts of information onto small areas.

CO2 laser coding technology can be used to code and mark almost every kind of surface, from glass to plastic to coated metals, across every kind of industry and any production line.
