流动轮廓图 The area with dense lines in the above picture represents the area with lower flow velocity; and the area with sparse lines represents the area with higher flow velocity.

11 Temperature at flow front
前端温度分布 Above figure showed the temperature at the part. Melt enters cavity at 280 C The polymer recommended temperature range: 270~290 C From above plot we can see that the temperature drop on the part are out of this polymer recommend rang and indicate flow relate problem were expected appear on this part, we suggest to injection this part by slow speed.

12 Pressure at V/P switchover

24 Conclusions &Suggestions
From the above analysis The cycle time is about: 1.5 (filling) (cooling + packing ) (open & eject) =27.5 sec This part will not have filling problem due to the pressure are within the moldflow recommend range. No weld lines were expected appear at this part. (refer page 16) Most of the air trapped appear at the edge of part that is easy to vent. (refer page 17) No sink mark appear at the surface of part. (refer page 19) This part have minimal uneven shrinkage at the X,Y,Z deflection.
