As well as classic extrusion, melt filtration, and gas venting processes of various plastics, MAS extrusion technology also enables the finishing of these commodity plastics with a multiplicity of additives. Post-consumer or post-industrial materials can be compounded extremely flexibly with reinforcing fibers (glass fiber, carbon fiber, or natural fiber), impact modifiers, stabilisers, or inorganic materials to improve form stability and fracture strength (using various filling materials such as chalk, talcum, or marbles).
The enormous conic concurrent twin screw enables the processing of all mill materials, as well as light recycling fractions, such as flakes, sheets, or fibers. Additives can be added via the large pour hole, eliminating the need for side springs.
he extrusion process is carried out at very low rotation speeds. Energy is inserted systematically in the homogenising section by the relatively high circumferential speed (large caliber in the rear area) in this section. The circumferential speed is comparatively low in the anterior mixing, gas venting, and pressurisation section. That’s why a simple heating-cooling combination is sufficient for temperature control in the discharge section. All this facilitates the highly energy-saving operation and material-friendly processing at the shortest process length, combined with excellent gas venting performance for the utmost economic efficiency in your production.
