The FG GROUP has invested in recent years on technology and innovation, in particular it has dedicated a section of a department of the headquarters to a modern machine of l.a.s.e.r Hardening.
This technology is adopted to harden the wear areas of the molds with the precision of an L.A.S.E.R. direct driven by an anthropomorphic robot to reach hardening depths that can vary between 0.8 and 1.5mm.
The surface heating cools suddenly thanks to the mass of the underlying steel that absorbs heat.
During the treatment, the surface temperature is controlled punctually by means of fast response optical pyrometers; with this system local melting problems are avoided, even if the laser beam passes over small holes or sharp edges, obtaining homogeneous heating near the latter.
The cooling speed is such as to produce quenching transformations without the aid of liquid quenching means traditionally used with induction hardening.
