With the TF420 fibre laser marking solution, Technifor have brought out a unit that is twice as compact as the previous generations, while keeping the same marking quality level, and providing a writing speed of up to 2.5 m per second, and a skipping speed of up to 5 m/s. It is designed for applications involving medium to large production runs: motor vehicles, medical fields, electrical or mechanical components, etc.

The TF420 is in a class apart, mainly because of its ease of integration. Thanks to its light source operating at 1.06 microns (diode) placed remotely in the control unit, its latest-generation new electronics, and a reduced number of optical components, the marking head takes up a volume of just 10 cu. dm. The light beam travels to the marking head along an optical fibre. The remote control unit can be fitted in a 19’’ rack and it features an integrated buffer memory.

The TF420 also provides a longer service life and enhanced reliability. Firstly, the use of a fibre laser increases the diode service life to 100,000 hours. Secondly, the TF420 marking head and its control unit have been designed with the lowest possible number of optical elements (no Q-switch, no crystal, no RF driver), to reduce maintenance and avoid drift in the settings of the optical components, to ensure constant marking quality over time. Thirdly, an electronic safety system featuring a reflectivity alarm stops the laser if the reflection level from the part is too high.

The TF420 system can be used to mark a wide range of materials, including plastics, metals, or ceramics, and also difficult surfaces such as cast aluminium, steel, or titanium.
