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
