| Abstract: |
| The three-dimensional models were established for wide sheet extruder die with both end feeding to simulate the flow field.The results showed that，the pressure gradually became uniform at lateral while it decreased at extrusion direction.Comparison study between 5 and 8 mm of damper height showed that the lateral velocity distribution of outlet area was affected by the height of damper，and by adjusting the height of damper properly，the extruding pressure and velocity of the fluid flow became more uniform at lateral. |
