Simulation is now well accepted as a scientific approach to casting methoding, ensuring design process parameters, internal quality, optimal yield and short development time of casting process. Method layout involves decisions regarding part orientation in mould, parting line, cores, cavity layout, feeders, neck and gating system. An improper method layout leads either poor quality or low yield, which affects the productivity. Method design is mostly carried out manually, using 2D drawing of the cast part. Then tooling is fabricated and the sample castings are produced to 3-4 trials to achieve sound castings, which involves lot of production cost in the from of wastage of manpower, time and hamper the day to day scheduled production. Computer simulation provides a clear insight regarding the location and extent of internal defects, ensuring casting are right as first time and every time.
