Method and apparatus for injection molding of semi-solid metals

摘要: A new method and apparatus for the injection molding of semi-solid materials (SSM). In this process (called Rheomolding), a superheated liquid metal is cooled into state in barrel special vertical injection-molding machine, with growing dendrites solid phase being broken small nearly spherical particles by shearing force generated screw barrel. Compared metal, SSM has lower temperature, shrinkage more stable flow pattern. Therefore, rheomolding can produce net-shape or metal-matrix-composite parts continuously at cost.
