Areka MCX-25/50D Twin-Screw Extruder and Compounding Line

The Areka MCX-25/50D is a co-rotating, intermeshing twin-screw extruder with a 25 mm screw diameter and a 50:1 length-to-diameter ratio. Its modular screw design allows conveying, kneading and mixing elements to be arranged for each process, while independently controlled heating zones stage melting, dispersion and devolatilisation along the barrel. Polymers, fillers, fibres and additives are introduced through the main feed or side-feed ports by gravimetric or volumetric dosing units, and vacuum venting removes volatiles. Downstream, a water bath and strand pelletiser yield granules, while a filament line produces feedstock for 3D printing. The system supports the development of thermoplastic compounds, dispersion of nanoparticle and carbon-based fillers, polymer blending, reactive extrusion and biopolymer processing, and provides recipe validation before scale-up together with specimens for mechanical, rheological and thermal testing.
