    摘要: A method for producing a thin magnesium based metal plate which comprises a casting step comprising supplying a molten metal of a magnesium based metal to a molten metal vessel, withdrawing the molten metal, and supplying it to the interstice of a casting twin-roll comprising a casting upper roll and a casting lower roll while applying a pressure to it, to cast it into a plate having a predetermined thickness and a predetermined temperature, and a rolling step comprising applying a pressure to the above cast plate with at least one pair of rolling rolls, to thereby produce a thin magnesium based metal plate; and an apparatus for practicing the method. The method has allowed the production of a thin magnesium based metal plate by plastic working with good efficiency, without the need of supplying additional heat energy in the rolling step.

    摘要: A metal flow system, for high pressure die casting of alloys using a machine having a pressurised source of molten alloy and a mould defining at least one die cavity, defines a metal flow path by which alloy received from the pressurised source is able to flow into the die cavity. A first part of the length of the flow path includes a runner and a controlled expansion port (CEP) which increases in cross-sectional area, in the direction of alloy flow, from an inlet end of the CEP at an outlet end of the runner to an outlet end of the CEP. A CEP exit module (CEM) forms a second part of the length of the flow path from the outlet end of the CEP. The increase in cross-sectional area of the CEP is such that molten alloy, received at the CEP inlet end at a sufficient flow velocity, undergoes a reduction in flow velocity in its flow through the CEP whereby the alloy is caused to change from a molten state to a semi-solid state. The CEM has a form which controls the alloy flow whereby the alloy flow velocity decreases progressively from the level at the outlet end of the CEP whereby, at the location at which the flow path communicates with the die cavity, the alloy flow velocity is at a level significantly below the level at the outlet end of the CEP. The change in state generated in the CEP is able to be maintained substantially throughout filling of the die cavity and such that the alloy is able to undergo rapid solidification in the die cavity and back along the flow path towards the CEP.

    摘要: An injection molding system includes a feeder (23) in which a metal is melted and a first chamber (30) into which a desired amount of melted metal is introduced. A piston (46) in a second chamber (50) first retracts to create suction, assisting in drawing in the melted metal into the second chamber from the first chamber and evacuating gas. A ram (32) then pushes some melted metal remaining in the first chamber into the second chamber, forcing out gas present in the second chamber. The piston then injects the melted metal out of the second chamber into a mold (14). The melted metal is maintained in a semi-solid state prior to injection into the mold.

    摘要: An apparatus for processing feed stock into a thixotropic state. The apparatus includes a barrel with first, second and nozzle sections. The first, second and nozzle sections are connected together and include surfaces that cooperatively define a central passageway through the barrel. The first section is constructed of a first material, the second end section is constructed of a second material and the nozzle is constructed of a third material. The first material exhibits a greater resistance to thermal fatigue and thermal shock than the second material while the nozzle section includes a bushing which inhibits heat transfer to the die, precluding excessive molding pressures and cycle times. The apparatus also includes a preheater for preheating the feed stock before entry into the barrel, a thermal gradient monitoring system, a novel robust nozzle construction, and a two-stage embodiment of the apparatus.
