Semipermanent Mold

Molten aluminum alloy is poured into a metal mold consisting of two or more parts which can be opened to extract the part.

Sand cores can be positioned inside the mold to create hollow cavities in the casting.

Solidification of the part takes place under the weight of the liquid metal riser, which is the last part of the casting to solidify, to compensate for shrinkage.


Suitable for very high volume production of quality castings.
Directional solidification for optimal distribution of microstructure and mechanical properties inside the part.
Good dimensional precision.
