Extrusion Dies
and Feedblocks

An Extrusion Die is the epitome of the words “Tailor-made” and requires the tool maker’s extensive special knowledge and experience.  esde Dies are perfectly integrated into the respective line for film and sheets.

First of all the manifold of the Extrusion Die is tailored to the customers’ specific requirements. Here we consider the width and thickness of the product as well as the specific kind of material and the desired output. For optimal melt distribution the coat-hanger manifold and the melt flow are simulated in great detail with the rear of the manifold flow channel in a rounded shape.

esde Extrusion Dies are able to easily adapt to many different tasks in the ongoing film production.  For example: Our deckling systems facilitate the width-reduction of the film up to 100 mm per side.  Furthermore we provide a fully automated parallel adjustment of the lower lip for conceivably easy setting of different sheet thicknesses.

• Extrusion Dies with slit widths from 145 to 4000 mm
• Finish on all flow surfaces: Ra 0.05 – 0.08 µm
• Surface finish on lip lands: Ra 0.02 – 0.04 µm
• Die body completely manufactured from tool steel, improved to 1100 N/mm2 

• Different coatings: Chromium, Chromium Nitrite, Nickel, Polymer-Impregnation, etc.
• Lip adjustment: Pressure, push-pull, differential thread, automatic
• Flex lip: Central adjustment („Fast-Gap“) for a faster positioning of the lower lip
• Upper lip: flexible, with restrictor bar
• Lower lip: fixed, removable, slidable, parallel adjustment (even in operation mode)
• Deckling: externally fixed, externally adjustable, internally adjustable, section deckling
• Insulation
• Lip tempering, lip heating
• Connection adapter
• Fastening and suspension attachments
• Trolley

For Coextrusion multi-channel Dies or Feedblocks are used.  They enable complex applications of up to 7 layers. 

The esde Feedblocks are equipped with fine adjusters to vary each layer.  All flow channels are individually supplied and purged with fresh melt.  Exchangeable selector plugs allow different layer structures.
