Hardening technology in perfection – decades of experience and newest technology

In 1939 HEKO GmbH has already carbonized chains via kiln annealing equipment. Since then the heat treatment of HEKO products has been developed consequently. As a result of regular investment in modern equipment and the continuous qualification of our personnel we are able to offer high-standard know-how. HEKO achieves high surface hardness by using most modern technology.

The new ModulTherm system represents the technological leadership within the sector of low pressure carbonizing. Flexible qualities of the ModulTherm system permit a quick exchange between different charges. HEKO is therefore able to supply other manufacturers of high wear resistant components with this progressive hardening technology. Capacities are available for charges of every volume.
