Abstract
DES PIECES MOULEES CONTENANT DE L'ALUMINIUM, COMPORTANT DES PASSAGES INTERNES ET DES OUVERTURES, SONT FORMEES A L'AIDE DE NOYAUX PROFILES. CES NOYAUX SONT PRATIQUEMENT INORGANIQUES, SONT OBTENUS PAR MOULAGE ET FRITTAGE ET CONTIENNENT DU CARBONATE DE CALCIUM. LES PIECES MOULEES D'ALUMINIUM OU D'ALLIAGE D'ALUMINIUM SONT FORMEES EN COULANT LE METAL FONDU DANS UN MOULE DANS LEQUEL EST DISPOSE LEDIT NOYAU DE CARBONATE DE CALCIUM, POUR DEBARRASSER LA PIECE MOULEE DU NOYAU, ON LA MET EN CONTACT AVEC UNE SOLUTION AQUEUSE D'UN ACIDE INORGANIQUE, DE PREFERENCE L'ACIDE NITRIQUE.
