Résumé : |
In the second part of the series, calculations were carried out on the throughput behaviour, pressure build-up capacity and the melting process on the basis of an exemplary geometry. These results are now to be examined in more detail and subsequently optimized. For this purpose, the effects of adjusting some selected geometry parameters have to be investigated and interpreted. |
Note de contenu : |
- Results of the first calculation
- Step 1 of Optimizing the geometry : shortening the metering zone
- Step 2 of optimizing the geometry : increasing the metering zone depth
- A multi-purpose screw geometry
- Table 1 : Geometry optimization, test 1 : Metering zone shortened, compression zone lengthened
- Table 2 : Geometry optimization, test 2 : Screw with increased flight depth
- Figure : Through empirical tests and simulation-supported test series, a screw can be designed in a tailor-made manner for the respective application
- Fig. 1 : First test for geometry optimization : Pressure curve along the screw at stroke position 50 mm
- Fig. 2 : Second test for geometry optimization : Pressure curve after the increase of flight depth by approx. 28 % |
