Flame-free Entry

avoids carbon loss and pre-oxidation.

If PM parts require a certain, precise carbon level after sin-tering the new flame-free entry is one of our best industrial furnace features to achieve this. aching a certain temperature but not yet under protective furnace atmos-phere carbon loss will occur. Once the carbon got lost, its almost impossible to ”repair“ this carbon failure afterwards inside the sintering furnace. Even with high content of carbon carrier gas. Therefore entry conditions at the

Precise carbon content of PM parts achieved by the flame-free furnace entry. Why?

Especially light PM parts passing the normal furnace entry flame are heated up still under oxygen of the surrounding atmosphere. Already re-
