An opportunity in laboratory extrusion with catalyst material.  We have recently had some considerable success with one of our customers working with the extrusion of small quantities of catalytic material.

- The customer required an extruder that would be able to work with batches as little as 10 to 15 grams of material through an approximate 1 mm die but wished to increase the surface area of the resulting dried extrudate.

- Working in conjunction with our designers and technical support team some options were investigated and the best being the use of “clover leaf” (or tri-lobe holes) in the extruder die.

- The dies were developed for the extruder attachment from our [Caleva Multi Lab](https://www.caleva.com/products/multi-lab-for-pellet-research-and-development/).  The same technology can also be used with the [Caleva Variable Density Extruder](https://www.caleva.com/products/spheronization-kit-variable-density-screw-extrusion/).

- If this sort of technology would be useful to you or if you have other ideas that you want to explore with us then why not [ contact us](https://www.caleva.com/contact/) for a focussed discussion and see how we will help you.
