Abstract

Die Erfindung betrifft eine Vorrichtung zum Stauchen poröser rotationssymmetrischer Sintermetallteile, wobei die Umformung bei hoher Wirtschaftlichkeit kontinuierlich erfolgt. Im Gegensatz zum Stand der Technik können bei der Erfindung poröse Sintermetallteile im Durchlaufverfahren auch mit Hinterschneidungen oder sonstigen oberfläch­ ennahen Profilierungen beziehungsweise Einformungen ver­ sehen werden.
