Project of the month August 2017:Multifunctional single screw line

The task:

  • Extrusion line to process TPU for a flat profile, for tubing, and to run a crosshead die to sheath cable strands.


Standard set-up

The solution:

  • Single screw extruder ME 45/5x30D to process TPU, combined with a fusion pump.
  • Calibration unit ME 10/6.1 with a closed water system integrated into a 2.0 m long intermediate frame.
  • Sample-Sizer roller haul-off with a depositing device.


Total length of the line 8,250 mm
