Laser marking is one of the most reliable, versatile, and cost-efficient product marking methods available. Laser technology is perfect for food, beverage, and pharmaceutical products where high quality coding, high-speed production line marking or permanent traceability is required. A laser marking machine can also be used for static marking, where the product is placed rather than on a moving conveyor.
How does laser marking work?
Laser marking (or laser coding) permanently changes the surface of the material (or substrate) being marked e.g. when laser coding on painted card, the top layers of paint are removed revealing the contrasting bare card underneath.
A concentrated beam of light is deflected by mirrors through a lens (or system of lenses) to form characters by removing material or coating from the product or packaging.
Computer controlled, high-speed galvo motors maneuver the mirrors, working in two planes and enabling the beam to be rapidly steered across the surface to be marked at a pre-defined distance.
Accuracy is guaranteed, giving you consistent and sharp marking of text, numbers, codes or graphics, and 24/7 operation without the need for users to manually intervene.
Linx Laser Markers
Formerly branded Xymark, Linx laser coders require no consumables and have no regular servicing requirements. Laser is a clean and cost-efficient marking solution for manufacturing and production lines. For more information on Linx laser markers and a range of laser applications, browse our catalog:
Industrial Laser Uses
CO2 laser technology caters for most coding and marking requirements across all manufacturing and packing industries, it can be used on almost any material, from glass to plastic and paper or card to coated metals.
When laser coding on glass, the laser marking machine creates micro cracks, scribing a permanent code into the material without weakening it.
When laser marking on plastic the same process changes the very chemical nature of the material, either melting the surface to leave the desired mark or causing a color change to make it visible.
Fiber Laser Marking
Linx Fiber 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 Fiber lasers ideal for marking very small components, or large amounts of information onto small areas.
