Trials on the esde Flat Film Extrusion Line at

our Technical Center

Every trial is an extensive “getting to know” of our customers’ specific plastic materials.

This way we obtain important parameters about the processing characteristics of the material and, on this basis we can customize our extruders, dies and downstream equipment. The possibilities for modifications are numerous and multifarious. Difficult extrusion tasks request the imagination and inventiveness of our designers. Based on the analyzed test results we prepare a customer-specific machine concept in economical and procedural balance.

As in the end always two questions must be answered:

“What does it cost” and “What do we gain”.

The following parameters were also determined and made available for the customer:

  • Exact description of screw, feed section and drive
  • Extruder screw speed (rpm)
  • Motor torque (%)
  • Melt pressure (bar)
  • Temperature on each barrel heating zone, die, polishing stack

Test Report

Trials at our technical center help to gain important insight into the customer's specific requirements.

Test result

TOP film at all operating points, extremely high throughput. However, limited throughput for thin film resulting from line speed.
