Definitions

  • DE-A-3416132 discloses an apparatus for casting, comprising: a pressure vessel; means for pressurizing the vessel, the pressurizing means being fluidly connected to the vessel; a crucible disposed in the pressure vessel within which material is in use melted; a mould chamber within which a mould is held, the mould chamber being in fluid connection with the crucible; and means fluidly connected to the mould chamber for evacuating the same; whereby melted material in the crucible can be drawn to the mould chamber as the evacuating means acts on the mould chamber.
  • the present invention provides a reinforced part characterized by being formed by forcing with a gas a melted material into a reinforcement contained in a mould chamber inside a pressure vessel.
  • the step of forming a solidification plug such that further evacuation is prevented from the pressure vessel 12, as shown in Figure 8, and the melted material is prevented from leaving the vessel 12 via the snorkel 30.
  • the continuous pressurizing from the pressure pump 25 of the vessel 12 forces the melted material 16 through the feeder tube 38 into the mold chamber 18. This continuous pressure causes the melted material 16 to penetrate into the fiber array mold 20 and eventually fill the fiber array mold 20, as shown in Figures 9 and 10.
