Quality assurance: Defective castings cost money to produce as well as recycle. Many internal defects (like shrinkage porosity) are caused by an incorrectly placed or sized feeder. This can be checked by modeling the current methods design and simulating the casting. Then the methods design is modified to eliminate the internal defect and improve the quality level of castings.

 

Yield optimization : Excessive number and size of feeders results in poor yield. The yield can be improved, while ensuring the desired casting quality, by optimizing the feeder and gating design. This is achieved by simulating many alternatives for methods design and layout, and selecting the most optimal one. Such an exercise is not possible by foundry trials due to the time and cost involved.

CAD Compatibility

 

The solid model of the as-cast part required for simulation can be created using a 3D CAD program, and exported or saved as an STL (ASCII) file. AutoCAST-X can import part STL files from all popular CAD programs such as Autodesk Inventor, CATIA, I-DEAS, Pro-Engineer, SolidWorks, SolidEdge and UG-NX. Foundries can also request part models from their OEM customers, who usually donít mind sending an STL file, since this cannot be modified and therefore offers some degree of protection.
