Cover Outline Dimension Purpose of Simulation To analysis original design, and check flow, cooling, and warpage. 400mm 300mm Cover Outline Dimension p. 2/12

Plastic Properties Used for Simulation Trade name: Zytel HTNFE8200 1. Melt Density 0.95516 g/cm^3 2. Solid Density 1.1467 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

Conditions of Injection Process Filling Conditions Mold temperature : 80.0 deg.C Melt temperature : 325.0 deg.C Injection time : 1.4 sec Cooling Conditions Cooling time : 50 deg.C Packing Profile 9.0 20.0 t(s) MPa 49.1 Packing pressure at 80% of Max. injection pressure Injection position (2) PRESSURE [MPa] HOLDING TIME [sec] 49.1 0.0 49.1 10.0 p. 4/12

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

Result: Temperature at Flow Front Flow front tempurature 321.8 - 327.5 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

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

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

Result: Average Volumetric Shrinkage 6.7% - 14.2% Things to look for: High shrinkage areas Non-uniform shrinkage areas Negative volumetric shrinkage areas p. 9/12

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

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. p. 11/12
