A Benchtop Extruder with Variable Die Diameter and Depth with Both Radial and Axial Extrusion
Only the Caleva Variable Density Extruder ® (VDE ®)can offer a selection of extruder die apertures and bore lengths for both radial and axial extrusion methods.
With aperture diameters from 0.2-2.0mm, and bore lengths from 0.2-12.0mm, the optimal length to diameter ratio (L:D ratio) can be selected to produce the ideal density extrusions to suit your application.
The extruder can be purchased with radial, axial or both configurations. The equipment can be upgraded later according to need.
The unique ability of the VDE ® to produce extrusions using either the Axial or Radial methods, coupled with the range of die L:D ratios allows for quick and easy laboratory evaluation of various densities and formulations. There is nothing else available that offers this degree of flexibility and ease of use in a single piece of equipment.
The VDE ® from Caleva, for the development of pellets by Extrusion and Spheronization. The most flexible and productive laboratory extruder available. The only bench-top extruder with variable die diameter and depth with both radial and axial extrusion!
