The pressure inside the cavity is called cavity pressure. It is usually smaller than the specific pressure due to pressure losses.
Sensors inside the mold are used to measure the cavity pressure and to compare it with the injection molding simulation.
The time-pressure curve of a complete cycle helps to validate the vp-switch, as well as the effect of the packing phase.
The part quality can be evaluated easier.
