Abstract

L'invention concerne un procédé de fabrication d'un collimateur de coulée. Ce procédé consiste à préchauffer un moule (102), à remplir ce moule de matière en phase liquide (110), et à appliquer simultanément un vide (104), de la chaleur et des vibrations (106) sur le moule jusqu'à ce que la matière atteigne une phase sensiblement solide.
