| Abstract: |
| A model for simulating the non-New tonian flow of rubber compound in pin barrel extruder was established.The characteristic curves of pressure field，flow field and screw were obtained by calculating with the model.The results showed that the extruder productivity decreased as the non-New tonian fluid characteristics of rubber compound strengthened and the backward fluxes resulted from the cuts on the screw channel increased；the pins on the barrel had little effect on the extrusion behavior；and the extrusion behavior of the pin barrel extruder was similar to that of the extruder with cut screw. |
