Abstract

L'invention se rapporte à un procédé de fabrication, comprenant les étapes suivantes : -introduire le matériau à mouler dans un moule (14); -disposer le moule dans une enveloppe (12) comprenant une prise de vide 05); -réaliser une dépression dans l'enveloppe par formation d'un écoulement gazeux par la prise de vide; -déformer le moule; -arrêter l'écoulement gazeux; et -appliquer une pression sur au moins une partie du moule, éventuellement avec interposition de l'enveloppe, au moins après l'arrêt de l'écoulement gazeux. L'invention se rapporte aussi à un dispositif pour mouler des pièces.
