A injection molding process injects a semi-solid slurry with a solids content ranging from approximately 60% to 85% into a mold at a velocity sufficient to completely fill the mold. The slurry is injected under laminar or turbulent flow conditions and produces a molded article that has a low internal porosity.

L'invention concerne un procédé de moulage par injection, qui consiste à injecter, dans un moule, une suspension épaisse semi-solide présentant une teneur en matière sèche variant entre 60 % et 85 % environ, à une vitesse suffisante pour remplir entièrement ledit moule. L'injection de la suspension épaisse, qui est effectuée dans des conditions de flux laminaire ou turbulent, permet d'obtenir un article moulé présentant une porosité interne peu élevée.
