Simulation in laboratory and compounding

The flexibility and high performance of the Brabender® twin screw technology allow for optimum adaptation of the processing machines for laboratory and small-scale production to all processing tasks relevant for most different polymers.

A special screw configuration software helps to build up the screws from a construction kit so as to perfectly suit to the respective application.

Extensive ancillary and downstream equipment enables modular construction of complete extrusion lines.

The basic steps of compounding can perfectly be realized with corotating twin screw extruders. This makes modular co-rotating twin screw extruders the ideal companion for plastics from synthesis up to recycling.

Profit from the harmonized, modular conception of screws and barrels for optimally realizing all processing steps (feeding, conveying, plasticizing, dispersing, reacting, venting, pressure build-up).

The system configuration of each model can easily be adapted to the individual processing task - anytime and at low cost. Or combine several processing steps within a continuously working extruder and use your Brabender® twin screw extruder as a modern in-line compounder.

Depending on the extruder size, on the material to be tested, and on the processing task, throughputs up to 60 kg/h can be reached. This opens up the entire application range to these extruders - from material development up to small-scale production of sheets and films.

Of course, the necessary additional equipment like measuring and control units or metering systems (gravimetric, volumetric, liquid) as well as down-stream equipment is available, too, allowing for modular setup of complete extrusion lines. Expansion is possible whenever needed.

  • Good feeding characteristics, even with materials with poor flow properties
  • High conveying constancy without pulsation or irregular thermal loads
  • Narrow residence time spectrum of the melt within the screw area
  • Constantly high quality of the extrudate
  • High output at long energy transfer
  • High energy input as compared to the free screw volume
  • Well-defined plastification time and purposive shearing
  • Gentle mixing at low energy input and high-quality homogenization
  • Gentle material treatment without temperature peaks even at high speed
  • Variable shearing by using mixing and kneading elements
  • Kneading blocks with different disk widths and offset angles
  • Good control of the pressure in the melt for optimum venting
  • Self-cleaning of the screws by intermeshing flights
