  1. Moldflow Analysis Report CASE 6k4.2_454042_0323 2005.3

  2. ANALYSIS AIMS • To analysis original design, and check flow,cooling,and warpage. 1280mm

  3. Plastic Material Introduction ASA Luran S 797 G:BASF 1. Melt Density 0.94527 g/cu.cm 2. Solid Density 1.058 g /cu.cm 3. Ejection Temperature 95 deg.C 4. Recommended Mold Temperature 60 deg.C 5. Recommended Melt Temperature 250 deg.C 6. Absolute Max. Melt Temperature 280 deg.C 7. Melt Temperature Minimum 240.0 deg.C 8. Melt Temperature Maximum 280.0 deg.C 9. Mold Temperature Minimum 40.0 deg.C 10. Mold Temperature Maximum 80.0 deg.C 11. Maximum Shear Rate 50000.00 1/s 12. Maximum Shear Stress 0.3000 MPa PVTprofile Viscosity model

  4. Part Introduction The thickness of part is balance,the base of thickness is 2.54mm.

  5. (100 ,390) (100 ,160) (100 ,-160) (100 ,-390) Feed System Design 1X1 cavities，pin gate, the size is 2.3mm.

  6. Processing conditions Filling Conditions : Mold temperature : 80.00 deg.C Melt temperature : 280.00 deg.C Injection time : 1.4 sec Flow rate: 1920 cm^3/sec Cooling Conditions: Coolant Temperature(Cavity) 50 deg.C Coolant Temperature(Core) 4 deg.C Packing Profile : P(MPa) Packing pressure at 40% Max. injection pressure 49.1 11.4 35.0 t(s) PRESSURE [MPa] STEP DURATION [sec] 49.1 0.0 49.1 10.0

  7. Circuit coolant temperature Circuit coolant temperature of part is shown by picture.

  8. Temperature (top),part Top temperature of part is shown by picture.

  9. Temperature (bottom),part Bottom temperature of part is imbalance,please increase the cooling at corner of part.

  10. Fill time Shown by picture is the filling status,the flow is balance .

  11. Temperature at flow front Temperature at flow frontis balance shown by picture，the melt Temp. is 280 degree .

  12. Air traps Air traps are show by picture，please attention venting。

  13. Weld lines The black lines is the possible weld lines.

  14. Shear rate The shear rate is highly,please attention the injection speed.

  15. Volumetric shrinkage Volumetric shrinkage is imbalance.

  16. Frozen layer fraction

  17. Injection Pressure & Clamp Force Max.: 2211.3 ton Max.: 122.6 MPa Pressure at injection location Clamp Force The Clamp force is bigger,because the Viscosity of material is big.

  18. Deflection– X direction Deflection of X direction is bigger. 1.9mm 1.7mm

  19. Deflection– Y direction Deflection of Y direction is big.

  20. Deflection– Z direction Deflection– Z direction is bigger.

  21. Summary The results： • The flow status good, the flow is balance,so the pressure of injection and packing is big. • The mostly deflection cause by cooling and shrinkage,please attention the cooling and packing to adjust.
