  1. PRODUCTIVITY IMPROVEMENT PRESENT METHOD Component Name : U- Bolt Component weight : 6Kgs Number of Castings per Mold : 2nos. Total Good Casting wt : 12Kgs Total Pouring wt : 20kgs Yield : 60%

  2. Picture shows Metal Filling at various intervals The colour scale shows the temperature at each location

  3. Picture shows Solidification at various intervals The colour scale shows the % of Liquid metal available

  4. Picture shows Hotspot inside the Casting & Feeder Hotspot specifies the isolated regions and solidification time

  5. Picture shows the possible porosity areas

  6. PRODUCTIVITY IMPROVEMENT PROPOSED METHOD Component Name : U- Bolt Component weight : 6Kgs Number of Castings per Mold increased to : 4nos from 2nos. Total Good Casting wt increased to : 24Kgs Total Pouring wt : 37.5kgs Yield increased to : 64% from 60%

  7. Picture shows Metal Filling at various intervals The colour scale shows the temperature at each location

  8. Picture shows Solidification at various intervals The colour scale shows the % of Liquid metal available

  9. Picture shows Hotspot inside the Casting & Feeder Hotspot specifies the isolated regions and solidification time

  10. Picture shows the possible porosity areas

  11. Result after implementation of this method Number of good casting per mold increased to 4 from 2 Yield improved by 4% from present method Additional cost spent on 2 cores and one sleeve per mold will be taken care by productivity increase.
