PROCESS AND APPARATUS FOR CASTING METAL ALLOYS UNDER PRESSION |
摘要 |
<p>A method and apparatus for injection molding a metal alloy wherein the alloy is maintained in a thixotropic, semi-solid state in a reciprocating extruder at temperatures above its solidus temperature and below its liquidus temperature in the presence of shearing and then injected as a thixotropic slurry into a mold to form a useful product. Following completion of the injection molding stroke the nozzle of the extruder is sealed by a solidifying a portion of the residue of the alloy remaining in the nozzle.</p> |
