Trials on the esde Inline-Extrusion Facility

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 in this trial and made available for the customer:

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

Test report

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

Test result

Good quality film, absolutely quiet extruder operation without any problems. Film at about 80–100 °C running out of inline polishing stack into deep-drawn machine.
