Patent 7469738 was granted and assigned to Husky Injection Molding Systems on December, 2008 by the United States Patent and Trademark Office.
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.
