UNIQUE BENEFITS

Security of investment:

Simple adaption of the flexible, innovative system to commercial changes

Adaptability:

The system can be modified due to simple adaption to different material fractions, thereby guaranteeing commercial flexibility.

Resource efficiency:

Targeted and therefore reduced energy input along the processing unit thanks to air cooling in the discharge area

Low consumption:

CO2– reduction thanks to revolutionary process technology

Easy operation:

Reliable and user-friendly handling thanks to logically designed touch panel

OPTIMIZED
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.

The twin-screw extruder
in deployment

The innovative MAS extrusion system is used in the processing of different plastics fractions, such as materials of the lowest bulk density, mill materials, flakes, new products, and fibers. Additives, filling materials, and fibers can be added directly via the feed opening without complicated and high-maintenance side dosing. This means:

  • Joint recycling and compounding of several products (e.g., LLDPE with LDPE, sheets with mill materials)
  • Higher-quality granulation of sheets compared to conventional extruders
  • Material inclusions (e.g., glue on sheets) are removed completely to ensure maximum product purity
  • Considerably higher recycling ratio and better quality possible for PET
  • No material back-up at the feed thanks to conical construction

Low maintenance
design

The conical construction facilitates generously dimensioned screw bearing and a massive screw construction while keeping the machine’s dimensions compact. Flexible conversions of existing systems are possible without any loss of quality or functionality.

At the same time, the twin-screw extruder stands out due to its comparatively low wear and tear and its easy maintenance. MAS screws consist of several elements that can be replaced individually. The extrusion system features state-of-the-art technology even after repairs and replacements thanks to ongoing, certified innovation and further development.
