Direct Extrusion

Direct extrusion or single-line compounding allows semi-finished products such as films, plates, pipes or profiles to be produced in a single process step. In direct extrusion, the intermediate granule production step, which is typical for plastics and other products, is skipped. As a result, the investment and operating costs and energy requirements of the production process are significantly reduced. Today, some products can only be produced by the single-stage direct extrusion method.

Polymer materials provide improved mechanical properties when exposed to less heat and shear forces through direct extrusion.


  • The granule production step, which requires a second process, is eliminated.
  • Polymer, will be expose to less heat and shear forces.
  • Formulation informations remains within enterprise.
  • Production planning and product design flexibility is high.
  • It saves energy
