DuraFlow   Feedblock & Co Extrusion Systems 

Allied Dies offers a superior designed and manufactured  Co-Extrusion Feedblock to compliment our current product line of Film, Coating and Sheet Dies.  Our Co-Extrusion Dies are designed with low-shear flow passages that enhance uniform layer distribution and improve overall gauge control, while minimizing residence time: resulting in less frequent cleaning, excellent color changes and the ability to process thermally sensitive polymers.  Our Dies equipped with DuraGauge     Lip Adjustment System offer a fast responsive and repeatable cross web gauge control for uniform roll build up.

As you know, the purpose of a Feedblock is to combine the melt stream of various polymers, arrange them into the appropriate layer sequence and deliver that "sandwich" of material to a Die.  The Feedlock should have provisions to compensate for some viscosity mis-match of the confluent polymers.  It should also match the shear stress and average velocity of the polymers as they converge.  We designed the DuraFlow    to optimize the co-extrusion process.  The layers are combined over a flat profile, rather than round, making any compensation for layer uniformity much easier.  The feedblock was designed to provide uniform layer distribution, minimize interfacial instability and process a variety of polymers.  Additionally, the design is very functional form an operational, maintenance and cleaning standpoint.

Whether its oxygen or moisture barrier for rigid or flexible packaging, adding colored cap layers, burying recycle, adding a heat - seal layer, making stripes or combining any performance enhancing polymers, Allied Dies, Inc. has the  expertise and products to help improve your product.
