Twin-Screw Extruder
SMART EXTRUSION FOR CIRCULAR SOLUTIONS
THE POWER OF CONICAL EXTRUSION
The MAS twin screw was developed specifically for deployment in recycling and achieves its full potential in the upcycling sector. Flexible, resource-efficient twin-screw extruders ensure the environmentally friendly processing of recyclable plastics fractions and the highest quality of the resulting granulate.
The proven MAS innovation is now used more than 200 times worldwide and generates high-quality material for the important recycling cycle. Experience top-level engineering.
OPTIMISED EXTRUSION PROCESS
Conventional twin-screw extruders are frequently converted and configured for use in recycling. MAS extruders were developed specifically for this very purpose and are a tailor-made and future-proof solution for twin-screw extrusion in the world of recycling. The innovative, patented MAS technology unites the excellent homogenization and degassing performance of co-rotating twin-screw extruders with robust mechanical engineering and a broad range of applications for a wide variety of recycling fractions to perfection. The patented conical co-rotating design of the process unit features a large feed opening. This means the extruder has a larger feed volume and can reliably collect light material fractions at low screw drive. The increasingly smaller diameter results in increasingly slower circumferential speeds toward the discharge, and thus lower shear and more environmentally friendly plastics processing.
This optimal balance of conical process unit, faster processing, shorter retention time, and lower cone revolutions increases the specific throughput volume and reduces energy consumption. Undesired byproducts, gasses, and odors are reduced to an absolute minimum. The result is considerably more usable high-quality granulate for the recycling and upcycling cycle.
