Patent abstract

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.
