Abstract
L'INVENTION CONCERNE LE MOULAGE D'ARTICLES METALLIQUES. LE PROCEDE DE L'INVENTION PERMET DE FABRIQUER UNE ROUE DE TURBINE 10 EN MOULANT TOUT D'ABORD SEPAREMENT LES AUBES 14, PUIS EN MOULANT LE MOYEU 12 DE FACON A ACCOUPLER LES AUBES 14 PREFORMEES. LE PROCEDE DE MOULAGE COMPENSE LA DIFFERENCE ENTRE LES COEFFICIENTS DE DILATATION DES AUBES METALLIQUES 14 ET DU MOULE DE CERAMIQUE QUE L'ON UTILISE POUR COULER LE MOYEU. APPLICATION A LA FABRICATION DES MOTEURS A TURBINE.
