| - | The pressure profile is calculated from the screw tip back to the location of the melt vortex | + | The pressure profile is calculated from the screw tip back to the location of the melt pool formation. Before this location, solid conveying takes place, which shows an exponential pressure build-up. |
| The pressure profile calculation begins at the screw tip. Based on the calculated throughput, the pressure drop within a computation interval is determined and added to the previous absolute pressure. In injection molding machines, the pressure in the screw antechamber (at the screw tip) results from the set back pressure. | The pressure profile calculation begins at the screw tip.
