Linx FSL20 & FSL50
Precision marking on many materials
Permanently mark on a wide range of materials, including metal, rubber, plastic, and packaging foils. 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. Text, machine readable codes, graphics and logos are all marked with extreme clarity for traceability; ideal for pharmaceutical, medical devices, automotive and electronics industries, as well as FMCG packaging.
About Fibre Laser Marking
Fibre laser marking uses a highly focused beam of light to permanently change the surface of a material, creating clear and precise marks without contact. The laser beam is controlled digitally to produce text, barcodes and detailed 2D codes at high speed.
Fibre lasers are especially effective for marking metals and hard plastics, delivering very fine, high‑contrast results that remain readable over time, while operating without consumables to help reduce running costs and maintenance.
““With our fibre lasers we have developed a coder that meets our customers’ most important criteria – easy integration, reliable operation and the flexibility to deliver high quality codes of any description across the widest range of substrates”
Mark Cooper, Senior Director Product and Marketing, Linx Printing Technologies
