Re: Imbalance during pack
Question:
In fill phase, what % of final part weight is achieved ?

89%, all geometry has received plastic at that point. After that, I am trying to get rid of sinks by adding the material during pack.

Re: Imbalance during pack
The problem you are seeing seems to be a difference in the relative pressure losses in the flow path form nozzle to cavity between the high-shear portion of the cycle (Fill) and the low-shear portion of the cycle (Pack). Brent, as usual, is on the trail of a solution. Typically you want to have the fill-only parts at 95 to 98% of final weight. If you can get more material into your cavities during Fill, then the pressure differentials during Pack should have much less effect.
