Modify the density, pore size and porosity of the extruded material

The Caleva CML extruder attachment is the smallest in the family of screw driven extruders that can offer the operator the ability to extrude the material at high, medium high, medium low, or low density. By management of the extrudate density physical properties of the extruded material can be influenced. The most important of these are likely to be:

  • Density
  • Hardness
  • Porosity

Other attributes of the material could be product dissolution rates, friability and other factors yet to be confirmed. Each of these would be product and process dependant.

Trials are currently underway to quantify these potential changes. These results will be reported here when we have them.  If you would like to have additional, and updated information, then please contact us (info@caleva.com) and we would be happy to discuss this further.
