Low Pressure

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.
