Abstract

Outillage pour l’injection d’une barbotine chargée Un outillage d’injection (100) comprend un moule en matériau poreux (110) comportant une cavité de moulage (113) destinée à recevoir une barbotine chargée de particules céramique, une enceinte en matériau rigide (130) dans laquelle le moule en matériau poreux est maintenu. L’enceinte comprend en outre un port d’injection (134), un évent d’évacuation (135) et un canal d’injection (1111) reliant le port d’injection à la cavité de moulage du moule en matériau poreux. L’outillage comprend en outre une douille en matériau non poreux (160) présente dans chaque canal d’injection (1111), la douille s’étendant entre le port d’injection (134) et la cavité de moulage (113) du moule en matériau poreux (110). Figure pour l’abrégé : Fig. 2.
