3. Plastic Properties Used for Simulation
Trade name: Zytel HTNFE8200
1. Melt Density g/cm^3
2. Solid Density g /cm^3
3. Ejection Temperature 95 deg.C
4. Transition Temperature 264 deg.C
5. Maximum Melt Temperature 350 deg.C
p. 3/12

4. Conditions of Injection Process
Filling Conditions
Mold temperature : 80.0 deg.C
Melt temperature : deg.C
Injection time : 1.4 sec
Cooling Conditions
Cooling time : 50 deg.C
Packing Profile
t(s)
MPa
49.1
Packing pressure at
80% of Max. injection pressure
Injection position (2)
PRESSURE [MPa] HOLDING TIME [sec]

5. Result: Fill Time & Path Line
Fill time contour
Things to look for:
Short shot - Hesitation - Over packing
Air trap - Weld position
p. 5/12

6. Result: Temperature at Flow Front
Flow front tempurature
deg.C
Things to look for:
Hot spots
( around the gate, and areas where excessive shearing heating occurs)
Cold spots
( indicating hesitation)
Checking whether the material is shearing heating or cooling excessively.
p. 6/12

7. Result: Clamp Force History Graph
Max. 85 tonne
Things to look for:
To check the clamp force whether exceeds the guideline value of injection molding machine or not.
p. 7/12

8. Result: Plastic Grow From Gate Position
Red color : plastic from lower gate
Blue color : plastic from upper gate
Things to look for:
Equal distribution of colors will also have a uniform filling pattern and be balanced.
If the distribution of colors is not equal, then the floe is unbalanced.
p. 8/12

9. Result: Average Volumetric Shrinkage
6.7% %
Things to look for:
High shrinkage areas
Non-uniform shrinkage areas
Negative volumetric shrinkage areas
p. 9/12

10. Result: Weld Lines and Weld Surface
Weld surface formation
Weld line position
Things to look for:
To check position of weld help identify structural problems, and visual defects like line, notch, or color change on surface of part.
p. 10/12

11. Result: Warpage, Deflection
Warpage contour
( Scale factor : 10 times)
Max. 1.7mm
Things to look for:
To check regions in which there is high deflection, and a way how the part was deformed by orientation, differential shrinkage and cooling effects.
