American Kuhne Inc. (Booth N65033): Single-screw extruders up to 12 inches in diameter. A new gearless, direct-drive extruder designed to run at conventional single-screw speeds.

Screws have been cored for cooling since the early 1960s. In many processes, however, screw cooling is not utilized. Here’s an optimal design for a screw-cooling system.

Twin-screw extruders are well known for their compounding ability, but Keith Luker advocates single-screw extruders by his company, Randcastle Extrusion Systems Inc., dubbed “orderly mixers ...

Mixing in Single Screw Extruders is a must-have practical guide to the subject of single-screw extrusion. Avoiding mathematical theory, except when absolutely necessary, this authoritative handbook ...

By choosing the appropriate extruder, manufacturers can optimize processes, enhance product quality, and reduce waste and costs. Whether it’s a straightforward single screw extruder or a sophisticated ...

Extrusion Technology Mixing things up While single-screw extruders dominate the recycling space, twin-screw extruders are widening their niche, especially for value-added products.

The Turbo-Screw is said to increase throughput in plastic foam extrusion. The cooling screw has cross-flight holes that improve mixing and reduce energy use. The average throughput increase is said to ...

A significantly more efficient degassing system enables raw materials to be used even with a humidity of up to 0.5 %, says the firm, so that predrying can be minimized or completely eliminated. Due to ...

A single-screw extruder can perform the process without need of a second extruder. In some cases, the material spends less than 5 minutes in the extruder before it is entirely broken down.

We’ve seen lots of homebrew plastic extruders before, most of which use repurposed auger-type drill bits as compression screws.
