The Bonnot Company takes pride in its continuous commitment to innovation, consistently developing cutting-edge extrusion solutions for a variety of new materials.
In the 1970s, The Bonnot Company received an unusual request from a prospective client who had deceased animal carcasses and wondered if they could be sent in for testing. Taking a bold approach, we accepted the challenge and, in doing so, pioneered the development of the first pet food extruder. Throughout our rich history, The Bonnot Company has been open to testing a wide range of materials on our extruders, exploring the potential for creating usable products. We offer customization options for size, hopper opening, screw geometry, barrel length, materials of construction, and virtually any other specifications necessary to develop innovative solutions tailored to the unique needs of each material or customer. The aforementioned list is not exhaustive, as we have successfully produced extruders for numerous materials not explicitly mentioned, including graphite extrusion, silly putty, modeling clay, and many others. If your material isn’t listed, it doesn’t imply that we lack a solution or are unwilling to undertake the development work required to create a new solution. Recently, we even received a request regarding human biowaste, and though our team might not have been overly enthusiastic, we are conducting testing nonetheles

3 Applications for Benchtop Extruders

Benchtop extruders, also known as laboratory extruders, are used across industries for a wide variety of purposes. The Bonnot Company has been helping labs and testing facilities create custom machines for decades — with so many different needs to fill, benchtop extruders aren't a one-size-fits-all solution. Our custom-built lab extruders have helped countless clients complete highly specific jobs and push the limits of innovation in their industries. What we've listed here are just a few of the many applications for benchtop extruders.

Basic Theoretical Factors in Extrusion Augers

If you take a bolt, having a nut on it, and revolve the bolt, in a fixed axis, both the bolt and the nut revolve. Then, if you hold the nut with a wrench, and revolve the bolt, in the proper direction, the nut will travel forward and fall off the end of the bolt. A clay auger works in a similar manner. Inside of the closed auger barrel there is a “clay nut” which moves forward on the screw. The clay nut is ephemeral. The clay nut is constantly being destroyed by passing off the end of the auger, and it is constantly being reformed by feed material entering the closed auger barrel from the feed hopper, or vacuum chamber.
