Break-through innovation: SyncroTherm®
The all new SyncroTherm® - unit from ALD Vacuum Technologies provides for the first time the complete and total integration of heat treatment into the manufacturing work center. With this unit, the case hardening process is fully synchronized with the cycle of soft-machining, therefore allowing a continuous "One-Piece Flow".
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.
