摘要: A method and apparatus for injection molding a metal alloy wherein the is maintained in thixotropic, semi-solid state reciprocating extruder at temperatures above its solidus temperature below liquidus presence of shearing then injected as thixotropic slurry into mold to form useful product. Following completion stroke nozzle sealed by solidifying portion residue remaining nozzle.
