The case hardening process is drastically accelerated in the SyncroTherm® -unit,  so that the process matches the cycle-time of soft-machining. Instead of big batches with multiple layers, the components are treated in one layer only. These so called “2D-batches” guarantee a rapid and very homogenous heat treatment for all heat treatment steps such as austenitizing, carburizing and quenching. This homogenous treatment guarantees optimum reproducibility of the heat treat quality.
