Scanned model analysis

Scanned model analysis

Dedicated software is used for surface interpolation. This "digital metrology is the starting point for a new clean CAD model.

Foundry simulation

Foundry simulation

Metal flow and cooling is simulated to save numerous real life trials, and to design the sand molds by predicting potential cracks or porosity.

3D printed sand core

3D printed sand core

Sand cores and mold parts are 3D printed on a "sandprinter" without tooling.

3D printed sand core

3D printed sand core

3D sand printing allows hollow sections and ducts to be directly integrated in the molds

Mold assembly

Mold assembly

This mold was made of 7 different sand parts.

Mold assembly

Mold assembly

The assembled mold is sealed, Only breathing holes and metal inlet remain open

Raw casting

Raw casting

Once cooled down, the sand is removed from the part and metal feeding ducts are cut away. Aluminium parts are tempered and quenched. The part then goes through X-Rays and die penetrant checks

Straightening

Straightening

In some case straightening is required after quenching.

Deep hole drilling

Deep hole drilling

Some ducts may be drilled for accuracy and clean surface finishing
