Marshmallow Pellet Extrusion Testing
How Bonnot's test room used a cooker extruder to develop a low-density marshmallow pellet that floats on water — and what it took to get there.
Custom Engineering
One of The Bonnot Company’s core competencies is our custom engineering. Oftentimes our competitors take the “one size fits all” approach to extrusion solutions. Our philosophy has always been and continues to be, modify an existing machine, or develop a brand-new design to achieve a customer’s objective. It is a strategic advantage for us.
Often we are approached with a new material, a new challenge, something that may not have been extruded successfully before.
Often we are approached with a new material, a new challenge, something that may not have been extruded successfully before. This gives the customer unique technology that best suits their process and offers a competitive advantage over their competition.

130+ Years of Custom Engineering Heritage
For over 130 years, Bonnot Company has thrived by embracing custom engineering. Our journey began with developing extruders for processing clay and sand into bricks, establishing us as a leading supplier in the industry. We then expanded into the chemical sector, creating extruders for soap production and later, for processing chemical catalysts.
