What is Twin-Screw Extrusion?

Twin-screw extruders are well-established in the industry for mixing, compounding and processing of viscous materials. They are used in a great variety of polymer, pharmaceutical and food applications. The flexibility of twin-screw extrusion equipment allows designing these machines specifically to the desired task.

Twin-screw extruders can have a conical or parallel design. The two screws can be counter-rotating or co-rotating, intermeshing or no-intermeshing. Also, the configurations of the screws themselves can be varied using different conveying and mixing elements.

Counter-rotating twin-screw extruders are used mainly for processing PVC products, such as pipe, profile, sheet, pellets and film. The co-rotating units are used for compounding materials where thorough mixing is important.

Co-rotating twin-screw extruders usually have modular configurations, which makes the equipment quite flexible for adapting to changing applications and material properties.
