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.

How to Select the Right Extrusion Cutting Machine

The Bonnot Company has been in the business of extrusion for over 125 years, so it's safe to say we've been around the block when it comes to creating high-quality machines for a variety of industries and applications. But the extruders themselves aren't the only things we specialize in — to ensure we can tackle any need, we've developed plenty of extrusion cutting machines to work right alongside them. Take a look at some of the extrusion cutting machines we offer and learn which ones might be best suited to your unique needs.

Food Extrusion Innovations That Can Enhance Food Manufacturing Efficiency

The demand for healthier snacks has skyrocketed in recent years, which means that snack recipes and their production processes have changed. Both affect the food manufacturing process since recipe and temperature changes can alter the most effective way for foods to be extruded.

How the Right Extruder Can Affect Catalyst Properties

The size and shape of catalysts can have a major effect on how much activity they produce and how effective they are at their jobs overall. Particle size, in particular, can increase activity or create pressure drops, which can not only affect the outcome of the reaction but they also can affect your bottom line. Catalyst production can be costly, so creating the best possible product every time is a must.

Extruder Types and Key Industry Capabilities

What can extruders do? To put it simply, just about anything. Extruders are a key component of the manufacturing process, so when combined with feeding, cutting, de-airing and other forms of equipment, they can create everything from pet treats to hydrocolloid used for colonoscopy bags. Let's explore the most common types of extruder machines and the industries they can serve.

What is an Extruder, and Does Our Company Need One?

To understand what an extruder is, we must first know what the process of extrusion is. Extrusion is when a material, usually pellets, dry powder, rubber, plastic, metal bar stock or even food is heated and pushed through a die. A die is essentially a mold that shapes the material as it is forced through the small opening to the other side. It's one of the most common ways to produce sheets and strips of stock metal, plastic and rubber shapes.

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.
