Molten aluminum alloy is fed, via a riser tube, into a metal mold by applying a controlled overpressure to the liquid alloy contained in a furnace positioned below the mold.
Sand cores can be positioned inside the mold to create hollow cavities in the casting.
Feeding during solidification is effected by maintaining a pressure differential between the furnace and the mold.
|Directional solidification terminating at the sprue positioned on the lower part of the mold, reduces the need for risers thus improving output.|
|High dimensional precision.|
|Suitable for high/medium volume production of castings which have very high level mechanical features.|
