Fixed Geometry Coextrusion Feedblocks

Ultraflow® I Coextrusion Feedblocks

With nearly over a decade of field-proven reliability, Ultraflow I Feedblocks are currently in operation at hundreds of manufacturing sites around the globe. Exchangeable, streamlined Flow Inserts, the heart of the Ultraflow design, combine polymer streams in an optimal parallel-path manner. Should the coextrusion requirements change dramatically, these inserts are readily exchanged without having to disassemble the feedblock from the line.

Ultraflow I-S Coextrusion Feedblocks

This is a highly versatile line of coextrusion feedblocks. EDI's dependable Selector Spool technology, (which enables layer sequence re-arrangement), is provided upstream of our streamlined Flow Inserts (which have a contoured manifold design, like small dies). Layer sequence arrangements can be preset upstream of the combining point in the feedblock by installing a customized Selector Spool, without the need to remove the feedblock from the line. Layers then pass through exchangeable, streamlined Flow Inserts, which combine polymer streams in an optimal parallel-path manner. Should the coextrusion requirements change dramatically, these inserts can be readily accessed and exchanged.

Ultraflow II-C Coextrusion Feedblocks

This family of feedblocks is ideally suited for dedicated coextrusion structures on production lines with low to moderate throughput rates. The captured-insert design renders it both compact and economical. For well-matched viscosities and thick skin layers, this design is highly effective. A minimal need for operator interface ensures product consistency. The Ultraflow II-C Feedblock is elegant in its simplicity.

In-Die Coextrusion Feedblocks

The in-die-feedblock allows the final critical layers to be added within the die; shortening the path length of these important layers. This feedblock also holds similar exchangeable, streamlined flow inserts; allowing the inserts to be replaced if your production requirements change.
