Twin-screw extruders use two co-rotating, intermeshing screws to continuously conduct feeding, conveying, plasticizing, shearing, mixing, and pressure build-up for stable and smooth extrusion. The extrusion process is the basis for production in engineering plastics compounding and pelletizing, functional masterbatch and additive processing, polyolefin polymerization and pelletizing in petrochemicals, plastic film, foamed materials, powder coatings, pet food and feed, lithium-battery and new-energy materials, and pharmaceutical manufacturing.
The extruder's processing section is made up of three main groups of assemblies: screw elements, screw shafts and barrels. All these assemblies work together to transport, plasticize, mix and react the material.
