Flex Vacuum Furnace

Our Flex is the most innovative and popular solution of ECM’s Low Pressure Carburizing furnace range.

The modular and compact design of the Flex vacuum furnace meets the highest demands in terms of productivity and part quality. The Flex can receive oil quenching cells (hot or cold), simple gas or reversible dual stream (up to 20 bar) quenching and heating cells, their number depending on the required production capacity. Convective cells to high temperature tempering are also available. A light heat-insulating transfer machine ensures that loads can move from one cell to another.

Our patents avoid the use of vacuum tight doors between different heating cells. An optional version AMS 2750 E is available. This modularity guarantees the possibility to mix any type of treatment recipe with a continuous workflow.
