摘要： A method and apparatus for thixotropic molding of semisolid alloys are disclosed. The method comprises of feeding a dendritic-free feedstock bar into an extruder barrel, melting a terminal portion of the feedstock bar into a semisolid slurry by heating it to a temperature between its solidus and liquidus temperatures, and using the solid portion of the feedstock bar as an one-time nullplungernull to inject the semisolid slurry into a mold cavity. The apparatus based on the present method, which is equipped without a regular extruder screw or plunger, uses a feedstock bar as a one-time plunger to inject semisolid slurries formed from a terminal portion of the same feedstock bar.

摘要： 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.
