Extrusion Heads

Our Extrusion Heads ensure 
excellent uniform distribution, 
precise melt transport, and short 
color-change intervals for all blow molding plastics. 
We make differences between:

  • Spider-type heads to produce mono-layer packaging (often canister, or containers)
    The technical conception of our Spider-Heads ensures uniform material distribution and is suitable for different sizes of heads, with die diameters from 25 mm up to 650 mm.
  • Coextrusion Heads (CoEx) to produce multi-layer packaging made of different raw materials. This procedure integrates barrier layers, conductive layers or bio-plastic-layers in seperate layers into the article. This gives you the technical solution for many special requirements on article properties out of the various areas of application. We offer proven solutions with multi-layer Extrusion Heads for up to seven material layers for every area of application.


We have extensive experience in the multi-layer Extrusion of hollow articles and are the world's leading Provider of 4 and 6-layer Systems for the production of hollow plastic articles with barrier properties.
All our products are designed for Long-term Performance and in comparison always the most cost-effective solution!

Accumulator Heads

Accumulator supported heads enable
a discontinuous production process and 
are usually used for:


  • Technical components (e.g. car ventilation systems, air ducts)
  • Large containers (e.g. barrels, IBCs, storage tanks)
  • Containers with high parison weights
  • Sequential Co-Extrusion products (SeCo = the extrusion of different materials one after the other)
  • Processing of technical plastics
  • Bottles with color gradation effects

Furthermore, an extrusion head equipped with an upstream accumulator is also suitable for continuous extrusion due to an integrated bypass system, thus  ensuring a variety of application options.
