Can anyone advise how to perform RJG Dynamic Cavity Imbalance?
Many thanks

Re: RJG Dynamic Cavity Imbalance
You essentially turn off pack/hold and get the parts about 95% full under the same conditions you derived in your fill viscosity study. Then weigh each cavity and see how balanced your fill is. There are many reasons for an imbalance; differences between cavities, worn gates, unbalanced cooling lines and different shear histories just to name a few.

Also make sure to have a charge (rotation) delay time of may be 5 seconds also. if not, since the gate is not frozen the back pressure may fill your parts.
