Hardening shop in Muurame, Finland

We have a big experience in a heat treatment of metals. Sten’s hardening shop was founded in 1981. Our hardening shop in Muurame is specialized in hardening of tools especially by gasnitriding, casehardening and vacuumhardening methods. Tools for the plastics processing industry i.e. injection moulding tools, die casting tools, blanking tools, punching and metal forming tools are hardened in state-of-the-art vacuum furnaces with maximum quenching pressure of 10 bars. Nitriding is done in two gasnitriding furnaces, each with possibility for nitrocarburizing and black nitriding. Our newest piece of equipment is the Ipsen vacuumnitriding furnace which will be in operation in August 2006. For case hardening we have two gascarburizing furnaces equipped with modern control and oxygen probes.
