Abstract[German]
Verfahren zum Herstellen, insbesondere Vergießen, eines Rotors, umfassend die Schritte: -Bereitstellen eines Rotors; -Einbringen von Vergussmaterial in den Rotor, wobei das Vergussmaterial zum Ende des Vergussprozesses eine erste Viskosität aufweist; Einbringen von Wärme in den Rotor ab einem zweiten Zeitpunkt, wodurch der Gelierprozess gestartet wird; -Nachdrücken von Vergussmaterial ab einem dritten Zeitpunkt, welcher zeitlich nach dem zweiten Zeitpunkt liegt.[English]
The invention relates to a method for producing, in particular for casting, a rotor, the method comprising the steps of: - providing a rotor; - introducing casting material into the rotor, the casting material having a first viscosity towards the end of the casting process; - introducing heat into the rotor starting from a second point in time, thereby initiating the gelation process; - pressing casting material starting from a third point in time which is after the second point in time.[French]
L'invention concerne un procédé de fabrication, en particulier de coulée, d'un rotor, le procédé comprenant les étapes consistant à : fournir un rotor ; introduire un matériau de coulée dans le rotor, le matériau de coulée ayant une première viscosité vers la fin du processus de coulée ; introduire de la chaleur dans le rotor à partir d'un second point dans le temps, ce qui permet d'initier le processus de gélification ; presser le matériau de coulée à partir d'un troisième point dans le temps consécutif au second point dans le temps.
