摘要 | The precision of ceramic component gotten by some Solid Freeform Fabirication processes based on paste extrusion is dependent to a considerable degree on paste extrudate. To get clearer understanding about paste extrudate, the experimental works were carried out to investigate some important extrudate features for ram extrusion process in this paper. The velocity, diameter, liquid content and mass of extrudate of alunima paste by ram extrusion were studied. The liquid content of extrudate tests show that the occurance liquid phase migration depends on the ram velocity. Without liquid phase migration, the extrudate velocities have a corresponding relations to extrusion force. The dilation of extrudate occurs in commonly used ram velocities. So extrudate velocities should not be calculated by nozzle diameter but by the average diameter of dilated extrudate. The mass of extrudate in the very end of extrusion is greatly reduced and should not be used. |
