Counter-rotating twin-screw extruders are primarily used for processing PVC products, including pipes, profiles, sheets, pellets, and films. Conical twin screws and barrels are extensively utilized in the extrusion of PVC pipes, profiles, and pelletizing processes.

Twin screws come in parallel and conical designs.

Counter-rotating twin-screw extruders feature two screws that rotate in opposite directions. This type of machine, often intermeshing, is commonly used in the profile, PVC, or wood composite industries.

These machines typically operate at much lower screw speeds and generally have significantly smaller length-to-diameter ratios. The opposite screw rotation results in lower shear compared to single or co-rotating machines.

Conical twin-screw extruders have a taper, with a feed section much larger than the end of the barrel. These machines often feature barrel venting, but their barrels and screws are not modular, meaning they might need to be customized for specific applications.
