Laser marking machine

Laser marking is a process that by giving out energy which is conveyed onto a material alters the surface permanently. Energy is carried away by high intensity beam called laser beam.
Laser marking technology is widely spread and has some advantages when compared to traditional technologies, just to mention:
Versatility, unalterability of the result, high definition of laser marking, no contact between tool and piece, efficiency, an easy integration in production lines, high speed and process repeatability and last but not least very low running costs.
laser marking meets the demands of the industrial fields such as: traceability, certification, customisation, decoration,

Thanks to its long experience Sei has so far dealt with different applications such as: Static off line marking with manual or automatic piece manipulators , in line static marking, dynamic in line marking, 3 D marking for moulds. Intra-volume marking inside transparent materials.
Cutting of very thin materials, colouring/ decolouring of fabrics are realised by a wide range of laser marking systems based on sealed CO2 laser sources from 10 to 300watts and Nd: Yag lamp pumped up to 120watts laser sources or diode pumped sources up to 60Watts.
