Extrusion 6-2023

The highly efficient design of the 800 Series Hybrid re- duces cost and size, as opposed to other me- thods of overlapping lay- ers. Essential benefits of the 800 Series Hybrid include eliminating weld lines in materials through pa- tented overlapping tech- nology, producing a more consistent finished prod- uct; reduced sensitivity to changes in viscosity; reduced sensitivity to changes in line speed; myriad material and multi-layer application possibilities; works in all tubing and jacketing applica- tions with a wide range of materials; low residence time; compact design and a low tolerance stack-up error factor, all re- sulting in improved concentricity. The 800 Series Hybrid extrusion tool greatly reduces stagnation, because over- lapping layers are more inherently bal- anced than single layers and also because each semi-deflector is “tuned to flush.” ➠ Guill Tool & Engineering www.guill.com Guill announced the introduction of a new version of its popular 800 series, known as 800 Series Hybrid. In some ex- trusion applications that utilize cross- heads and inlines, layers of the exact same material are applied multiple times, using a single die. This method is used to reduce the propensity for errors caused by gels breaking through a thin wall, weld lines, inconsistent wall thickness, plus ma- terial and process variations. Additional errors include difficult-to-process materi- als and demanding applications where there is zero fault tolerance. Seeking to design the next generation multi-layer die to overcome these chal- lenges, the engineers at Guill looked for a way to incorporate this technology into an updated version of the 800 Series. This led to the creation of the 800 Series Hy- brid. The inherent benefits of the 800 Se- ries are retained, including compact design, low residence time and a com- mon deflector bore that eliminates toler- ance stack up. The challenge was to create a hybrid design that incorporates the benefits of layer overlapping, while reducing unnecessary complexity and making the technology more cost-afford- able for customers. This was achieved by New 800 Series Hybrid Extrusion Tooling announced Conventional deflectors must simultane- ously achieve a balance between flushing, balancing and eliminating the weld line. There is less difference between the slow- est moving material and the fastest mov- ing material in the deflector channels, thus making the viscosity more consistent in the deflector. x 300 mm) macht das eine Gewichtsein- sparung von 4 kg bis 4 kg Kunststoff, die nicht produziert, verarbeitet, recycelt oder entsorgt werden müssen.
