Extrusion International 4-2022

24 Extrusion International 4/2022 INDUSTRY NEWS  On August 1, 2022, Next Generation Recyclingmaschinen (NGR) saw a personnel change at the top management. Gerhard Ohler took over the role as CEO of Next Generation Recycling maschinen GmbH, based in Feldkirchen/Austria, succeeding Wolf- gang Steinwender, who has held this position since May 2020. Ohler has many years of international experience in extrusion technology and plastics recycling. Josef Hochreiter, CEO of Next Generation Group: "I am delighted to have gained an experienced manager for us in Gerhard Ohler. With this appointment, we will not only be able to successfully con- tinue along the pathwe have chosen, but also to break newground in plastics recycling. We have now created the best conditions to realize our mission "working for a better future" together with a highly motivated team and to continue to develop and build highly efficient recycling machines for our customers in the future.

In some extrusion ap- plications that utilize crossheads and inlines, layers of the exact same ma- terial are applied multiple times, us- ing 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 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 gen- eration multi-layer die to overcome these challenges, the engineers at Guill looked for a way to incor- porate this technology into an up- dated 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 toler­ ance stack up. The challenge was to create a hybrid design that incorporates the benefits of layer overlapping, while re- ducing unnecessary complex- ity and making the technol- ogy more cost-affordable for customers. This was achieved by overlapping layers in each semi-deflector, using a single cone. The highly efficient de- sign of the 800 Series Hybrid reduces cost and size, as op- posed to other methods of overlapping layers. Essential benefits of the 800 Series Hybrid include eliminat- ing weld lines in materials through patented overlapping technology, producing a more consistent fin- ished product; reduced sensitiv- ity to changes in viscosity; reduced sensitivity to changes in line speed; myriad material and multi-layer ap- plication possibilities; works in all tubing and jacketing applications with a wide range of materials; low residence time; compact design and a low tolerance stack-up error fac- tor, all resulting in improved con- centricity. The 800 Series Hybrid extrusion tool greatly reduces stagnation, be- cause overlapping layers are more inherently balanced than single layers and also because each semi- deflector is “tuned to flush.” Con- ventional deflectors must simulta- neously 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 mak- ing the viscosity more consistent in the deflector.
