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.
Bonnot machines are built to last. Many are still running after decades of continuous use. But there will always be some parts that need replacing after years of hard work. For high wear, highly abrasive applications, such as chemical catalyst or carbon products, we offer a rebuild program.
As we have a dedicated hands-on approach to building your extruder, one of our vastly experienced engineers will know the inner workings of your machine. This translates into expert support to advise your maintenance and production team on the optimal solution.
When you need us, we react quickly, getting you back up and running as soon as possible. Our field service team will work closely with Bonnot HQ in Ohio to get you the parts you need…stat! We even keep an inventory of your machine’s spare parts on our shelves so we can send them to you in the case of a sudden need for a replacement park.
Full service operation
Experience in building machines
Cost effective
Here at Bonnot we also specialize in refurbishing and rebuilding our equipment and parts, which means that sometimes a rebuild can be a more cost effective solution. We can return the equipment and parts to original factory condition, and also take this opportunity to improve the design by incorporating newer technology.
This approach can be a more cost effective option for you when you’re looking to increase production. We can work with you to provide a recurring rebuild program that will save you money and reduce downtime.
All bushings and seals are replaced at this time also to return a machine to you ‘as new’. At Bonnot we have full manufacturing capabilities in house, so we can respond to emergencies for all parts in a very quick fashion. Please contact us if we can help you with anything we’ve touched on here…

Research and Development is rarely a straight line from problem to solution. More often, it is a series of adjustments, observations, and refinements.
