Abstract

Des produits en alliage sont obtenus au moyen d'un moulage de précision à modèles perdus sans cire. Un modèle de cuve de moulage en céramique (34) définissant une forme de produit souhaitée est numériquement divisé en sections (10, 40, 42). Chaque section est transformée en un outil maître en alliage mou (14) incluant des inserts de précision (20) afin de pouvoir produire de petits détails. Un moule flexible (24) est coulé à partir de chaque outil maître et une section de la cuve de moulage en céramique est coulée à partir du moule flexible respectif. Les sections de la cuve sont assemblées en alignant des éléments de précision coopérants (58, 60) coulés directement dans chaque section et la partie d'alliage y est coulée. Aucune cire ni aucun outillage de modelage en cire ne sont nécessaires pour produire le produit en alliage coulé. Des éléments de surface usinés (54) peuvent être inclus à la fois sur les surfaces intérieure et extérieure des sections de coquille.
