Abstract
L'invention concerne un procédé de production d'objets à âmes internes moulés en matière plastique. Ledit procédé consiste à introduire une matière plastique dans la cavité d'un moule, à injecter un fluide de mise sous pression dans la matière pour la faire couler et l'obliger à épouser le profil de la cavité, la pression du gaz étant maintenue jusqu'à ce que la matière se solidifie et se supporte d'elle-même. Application à la production d'objets à âmes internes pouvant être utilisés dans les applications telles que des portes, des meubles, des plafonds, des parties internes d'avions et d'automobiles, des bacs de batteries, etc.
