esde Extrusion Dies We manufacture customized extrusion dies – based on modular designed die bodies, for specific applications, which fit perfectly into the line. In Order to fit We start with the customization of the manifold. Here we consider the width and thickness of the product, the specific kind of material and the required output. For an optimal melt distribution the coat-hanger manifold and the melt flow are simulated in great detail. The rear of the manifold flow channel has a rounded shape. Co-Extrusion For co-extrusion we use multi-channel dies or feedblocks. They enable complex applications of up to 7 layers. The feedblocks are equipped with fine adjusters to vary each layer. Exchangeable selector plugs allow different layer combinations as all channels are individually supplied and purged with fresh melt. Flexible and individual esde lines offer various options and are tailored to the customers’ specific requirements. For example our deckling systems facilitate the width-reduction of the film during production. We can also provide fully automated parallel adjustment of the lower lip for setting and adjustment of different sheet thicknesses. Configuration of the extrusion dies We offer a great variety of options: Extrusion dies with slit widths from 145 to 4000 mm Entire die body made of tool steel, improved to 1100 N/mm2 Different layers: Chromium, Chromium Nitrite, Nickel, Polymer-Impregnation, etc. Surface finish on all flow surfaces: Ra 0,05–0,08 µm

Surface finish on lip lands: Ra 0,02-0,04 µm Lip adjustment: Pressure, push-pull, differential thread, automatic Flex lip: Central adjustment („Fast-Gap“) 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 Adapter Fastening and suspension attachments Trolleys Film Extrusion Die with internal deckling, provides the optimal approach to the roll gap, slot width 2,300 mm Film Extrusion Die with...
