Definitions

  • the invention relates to a die casting process for the production of low-gas, low-pore and low-oxide workpieces, in particular castings of approximately 1 to 3 kg shot weight, made of metals or their alloys, such as aluminum and aluminum alloys or the like, by means of a preferably horizontal cold chamber die casting machine Known type, the transport of the metal from the melting or holding device (holding furnace) into the filling chamber by means of vacuum through the nozzle of a suction pipe and the die is kept under vacuum.
  • An advantageous embodiment of the method according to the invention when using alloys with a lower fluidity than the aluminum alloys based on aluminum-silicon, aluminum-silicon-magnesium, aluminum-silicon-copper or similar alloys consists in that at Use a nozzle of 6 mm diameter on the suction pipe of the filling chamber via the suction pipe from 0.35 to 0.45 kg of molten metal per second from the start of the vacuum build-up until the shot is released and the average flow velocity of the melt at the smallest cross-section (nozzle) of the suction pipe to approx. 6.0 to 7.0 m / sec. is set.
