Abstract

L'invention concerne un moule de co-injection à cavités multiples et un procédé permettant de produire simultanément une pluralité d'articles multicouches. Ce procédé fait appel aux éléments suivants : une structure de moule dans laquelle sont formées une pluralité de cavités, une première source d'alimentation qui fournit des quantités dosées d'un premier matériau de moulage, une seconde source d'alimentation qui fournit des quantités dosées d'une second matériau de moulage, un système (22, 24) de canaux chauffants communiquant avec la première et la seconde source d'alimentation, et permettant de transporter séparément les quantités dosées du premier et du second matériau dans une région adjacente à chacune des cavités. Cette région comprend un passage (16) commandé par une tige (30), et conduisant à la cavité (12) adjacente à travers une porte (14) qui présente la même section transversale que le passage (16). La tige (30) chasse la matériau du passage et assure le compactage dans la cavité.
