Geo designer sand casting
- 2. Powered by CAST-DESIGNER SAND CASTING Geo-Designer
- 3. Powered by CAST-DESIGNER Objective • Objective of this case study is to demonstrate capabilities of GEO-DESIGNER, DFM Software for CASTINGS. • Through DFM lots of time, effort, and material can be saved, which eventually reduce product development cost. • GEO-DESIGNER can help engineer to check various deign concepts they have in their mind at the early stage of design before go for full simulation. • The DFM analysis takes approximately 5-10 minutes which helps to validate your gating system before for full simulation.

- 13. Powered by CAST-DESIGNER MDI- Mass Distribution Index Based on the change in MDI value, the circumference of the part gets transparent. Finally it will show you the thick mass region in the casting which likely to become a shrinkage porosity. It can be checked in part stage itself. MDI- Mass Distribution Index
- 14. Powered by CAST-DESIGNER Geometry Analysis Geo-Designer Geo Designer is a quick up-front DFM (Design For Manufacturing) Analysis Tool in Cast Designer. Mass Distribution Index (MDI) Analysis. It is highly useful to find thick region or high mass region in the part. Normally, the high mass regions are solidified in the last. Mass of the part is calculated using Ray method (360 degree). MDI Results: MDI 1.0 means regions with around 1.0mm thickness becomes transparent. Regions above MDI 1.0 is highlighted in corresponding colour in the colour bar. By keep increasing the MDI value, regions with highest mass / thickness can be determined. These are generally called as “Hot Spots”. These regions normally create Shrinkage porosity in the part.

- 28. Powered by CAST-DESIGNER Summary • Conclusion of the MDI- Mass Distribution Index – Found isolated regions in the casting geometry. – Those identified regions compensated with higher modulus riser/feeder geometries. – Based on the MDI results the Riser/feeder geometry can be modified. – Once the Riser/feeder geometries are corrected it can be go for further Simulation process.
