 4PO5 Upper CasingBrand new casting |
---|
 Scanned model analysisDedicated software is used for surface interpolation. This "digital metrology is the starting point for a new clean CAD model. |
---|
 Foundry simulationMetal 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 coreSand cores and mold parts are 3D printed on a "sandprinter" without tooling. |
---|
 3D printed sand core3D sand printing allows hollow sections and ducts to be directly integrated in the molds |
---|
 Mold assemblyThis mold was made of 7 different sand parts. |
---|
 Mold assemblyThe assembled mold is sealed, Only breathing holes and metal inlet remain open |
---|
 Raw castingOnce 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 |
---|
 StraighteningIn some case straightening is required after quenching. |
---|
 Deep hole drillingSome ducts may be drilled for accuracy and clean surface finishing |
---|
 MachiningMachinig is made on a 5 axis machining center |
