DuraFlow Feedblock & Co Extrusion Systems
![R-in-a-circle-trademark-1024x538noback c](https://static.wixstatic.com/media/4af150_2044dbf84ee54f01b224fddcc2519a08~mv2.png/v1/fill/w_14,h_14,al_c,q_85,usm_0.66_1.00_0.01,enc_auto/R-in-a-circle-trademark-1024x538noback%20c.png)
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.
