FAQs- Linx Fibre Laser Coding Machines
Fibre laser coding machines are used to permanently mark text, barcodes, DataMatrix codes, QR codes, serial numbers, logos, and date/batch codes onto a wide range of industrial materials — including metals, plastics, rubber, and packaging foils. They are commonly used in pharmaceutical, medical device, automotive, electronics, and FMCG industries where permanent, tamper-proof traceability codes are required.
Fibre laser coders such as the Linx FSL20 and FSL50 can mark on metals (including aluminium and stainless steel), rigid and flexible plastics, rubber, and packaging foils. Because the laser ablates or engraves the surface rather than using ink, the code is permanent and resistant to heat, moisture, and abrasion — making it suitable for harsh industrial environments.
The Linx FSL20 has a nominal laser output of 20W, while the Linx FSL50 has a nominal laser output of 50W. The best choice depends on the substrate, line speed, mark size and contrast requirement. Linx can test your material to confirm the right configuration.
The Linx FSL20 and FSL50 fibre laser coders are built around a laser tube with a rated lifespan of over 100,000 hours. At continuous 24/7 operation, that equates to more than 11 years of use, significantly reducing downtime and replacement costs compared to CO₂ laser coders or ink-based coding systems, which require more frequent consumable changes and maintenance.
