  • Publication number: 20090098234
    Abstract: A screw is provided for an injection unit having an inner diameter surface and a raised outer diameter surface on the screw flights. Carbide inserts such as a carbide wire or a plurality of short carbide inserts are mounted to the outer diameter surface to reduce wear on both the screw flights and the inner surface of the extrusion barrel.

  • Patent number: 7469738
    Abstract: 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.

  • Patent number: 7255151
    Abstract: An injection-molding process for molding a metal alloy into a near net shape article that is characterized in that the processing temperature of the alloy at injection is approaching the liquidus, preferably having a maximum solids content of %, whereby a net-shape molded article can be produced that has a homogeneous, fine equi-axed structure without directional dendrites, and a minimum of entrapped porosity. Advantageously, the resulting solid article has optimal mechanical properties without the expected porosity and solidification shrinkage attributed to castings made from super-heated melts.

  • Patent number: 7237594
    Abstract: An injection-molding process for molding a metal alloy into a near net shape article that is characterized in that the processing temperature of the alloy at injection is approaching the liquidus, preferably having a maximum solids content of 5%, whereby a net-shape molded article can be produced that has a homogeneous, fine equi-axed structure without directional dendrites, and a minimum of entrapped porosity. Advantageously, the resulting solid article has optimal mechanical properties without the expected porosity and solidification shrinkage attributed to castings made from super-heated melts. Also disclosed is a metal-matrix composite including a metallic component, and also including a reinforcement component embedded in the metallic component, the metallic component and the reinforcement component molded, at a near-liquidus temperature of the metallic component, by a molding machine.
