Extrusion International 3-2020

22 Extrusion International 3/2020 INDUSTRY NEWS Guill announces the introduction of a new version of its pop- ular 800 series, known as 800 Series Hybrid. In some extrusion applications that utilize crossheads 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, in- consistent wall thickness, plus material and process variations. Additional errors include difficult-to-process materials and demanding applications where there is zero fault tolerance. Seeking to design the next generation multi-layer die to over- come these challenges, 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 Hybrid. The inherent benefits of the 800 Series are retained, including compact design, low residence time and a common deflector bore that eliminates tolerance stack up. The challenge was to create a hybrid design that incorporates the benefits of layer overlapping, while reducing unnecessary complexity andmak- ing the technology more cost-affordable for customers. This was achieved by overlapping layers in each semi-deflector, us- ing a single cone. The highly efficient design of the 800 Series Hybrid reduces cost and size, as opposed to other methods of overlapping layers. Essential benefits of the 800 Series Hybrid include eliminating weld lines inmaterials through patented overlapping technol- ogy, producing a more consistent finished product; reduced Guill Tool & Engineering www.guill.com 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 ap- plications with a wide range of materi- als; low residence time; compact design and a low tolerance stack-up error factor, all resulting in im- proved concentricity. The 800 Series Hybrid extrusion tool greatly reduces stagnation, because overlap- ping layers are more inherently balanced than single layers and also because each semi-deflector is “tuned to flush.” Con- ventional deflectors must simultaneously achieve a balance between flushing, balancing and eliminating the weld line. There is less difference between the slowest moving mate- rial and the fastest moving material in the deflector channels, thus making the viscosity more consistent in the deflector. Eco-PET Reduces Plastics Consumption in Packaging Packaging solutions made from Eco-PET are 20 to 30% lighter than conventional PET packaging. Depending on the application, they can be manufactured translucent or in any desirable color. The pearlescent effect gives the packaging a very elegant and high-quality look and feel. Thermoformed trays and cups made from Eco-PET feature excellent rigidity and are insensitive to scratch marks making them suitable to safely stow berries or other delicate foods. This helps not only to reduce food waste but also protects the environment, as each produced tray uses 20 % less plastic. It goes without saying that lower plastics consumption is significantly cutting manufacturing cost. Eco-PET packaging can be produced from recycled bottle flakes and is fully recyclable after being used itself. It can be manufactured on any existing or new PET sheet extrusion line by incorporating Promix technology. By adding small- est amounts of environmental friendly gases, microcells are generated, resulting in a lighter product weight.
