| - | ===== Residence time ===== | ||
| - | |||
| - | For the calculation of the residence time the same conditions as for the calculation of | ||
| - | the melting profile have to be fulfilled. In addition to this the injection time is required | ||
| - | with **PSI**. | ||

| - | **Realization of the theoretical principles** | ||
| - | |||
| - | The screw is divided into at least 150 parts for the residence time calculation. Up to | ||
| - | the point of melt pool formation (OSW), there is no difference between the calculation of the | ||
| - | minimum residence time and that of the average residence time, since a block flow is | ||
| - | assumed, here. From the point of melt pool formation (OSW) the residence time is calculated | ||
| - | with allowance for the current density. When the residence time calculated equals the | ||
| - | metering time calculated, the residence time and the injection time will be added. | ||
| - | This procedure is continued until the screw tip is reached. | ||
