Single-screw extruder „Standard Line“ with Co-extrusion

We count on the single-screw extrusion technology.
With our long-developed and unique feed zone, up to 100% recycled plastic can be processed. The specially designed screws, which are calculated down to the smallest detail, guarantee fast and, above all, gentle melting of the material.

This guarantees a high quality of the melt.

Extrusion die

Extrusion die

We also have many years of experience in the manufacture of wide gap dies. Each die is calculated and designed in-house. Therefore, we are enormously flexible and can adapt them to any customer requirement.

In our portfolio we have:

  • internal / external deckled dies
  • with / without automatic die
  • with / without restrictor bar

Single-screw extrusion with direct drive and high-performance energy control means significant energy-saving options.Proven single-screw solutions also mean:

  • Small number of rotating parts
  • Low friction, abrasion and wear
  • Low shearing stress on parts and materials
  • Gentle material melting process
  • High IV retention
  • Low energy consumption
