What option to use for your Fill+Pack Velocity/Pressure switchover point?

Let’s talk about Pressure (again). More specifically, how we transfer from the first stage filling to 2nd stage packing.
 
When setting up a Fill+Pack – you have several options to choose how you transfer. I usually use By % Volume Filled (98%) since that is how I was taught to process in college. If my customer is using a pressure transducer, I can choose By pressure control point. Several of my customers use Automatic which lets Moldflow select the transfer point (usually this is around 99% full but can vary based on the model). You can also choose to transfer by pressure, ram position, clamp force, or by time.
