This is a question similar to others I often receive…
If I’m using a DII process, why should I turn off pack/hold time when I am filling 98% during first stage?
Turning off pack and hold is a great way to verify your fill is properly established, especially when you document the fill weight.
This is typically done when you are establishing a process… or troubleshooting.
Usually when I develop a process… I document the fill (short shot), pack (full with sinks), and then hold (gate seal).
I also like to take a picture of the 1st stage short shot to document the appearance.
