  4. 4. Analysis results Cycle time 31.79s Maximum injection pressure 44MPa Clamp tonnage during filling/packing maximum clamp force 293tonne/ 433tonne Maximum Melt Front Temperature 230.7 Minimum Melt Front Temperature 111
  5. 5. Preprocess and mesh statistics Specification: ,
  6. 6. Material Data General: Recommended Processing: Rheology: PVT properties: Specification: Material is pp simulation infromation can find in Moldflow material data sheet.
  7. 7. Initial Nozzle/Gate Locations and sizes Gate dimension 1.5MM Cold/Hot runner& dimension Hotrunner 10 Gate type : 2 cavities hot runner Valve control No Specification: Gate location and size decide is based on mold design experience, Part modify refer to moldflow analysis and T0 samples. D1.5 D10
  8. 8. Fill time - Animate Shift+F5 watch the animation Short shot No short shot, fill is keep balance Specification: Blue to red stand filling order, for evaluate filling balance, red area is the finished at the end.
  9. 9. Fill time - Contour Short shot No short shot, fill is keep balance Specification: Blue to red stand filling order, for evaluate filling balance, red area is the finished at the end.
  10. 10. Bulk temperature at end of fill Specification: Temp keep balance, no obvious temp difference.
  11. 11. Pressure at V/P switchover V/P control Filling control Volume % at V/P 97.33% Specification: From thebmV/P pressure, pressure keep balance
  12. 12. Pressure at the end of fill Specification: Analysis by synthesis, pressure keep balance
  13. 13. System Pressure(Nozzle Pressure & Packing pressure Max. Pressure Time 1.62s Max. Pressure 55MPa Packing time 10s Packing pressure 44MPa Specification: Max. pressure 55MPa
  14. 14. Flow Front Temp Flow front Temp. Difference Temp. Diff. at A surf. (230.7-111 Recommended material Temp. 220 -260 Specification: Flow front Temp in the range of recommended material temp.
  15. 15. Clamp Force Max. clamp force 433tonne Clamp force limit tonne Specification: injection machine tonne meet to molding requirement.
  16. 16. Air Traps Specification: The part red circle pink point it indicate prelim air trapping location, all the place should be considerate add air veting.
  17. 17. Weld Lines Specification: Color lines indicate weld lines location.
  18. 18. Volumetric shrinkage at ejection Specification: The max. shringkage is 13.18%, Min shringkage is -0.4% at ejection. if increase the gate size , extend packing time can reduce volumetric shrinkage.
