26 Extrusion International 5/2019 EXTRUSION INTERNATIONAL INDUSTRY NEWS New800 Series Hybrid Extrusion Tooling 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 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, inconsistent wall thickness, plus material and process variations. Additional errors include difficult-to-process ma- terials and demanding applications where there is zero fault tolerance. Seeking to design the next generation multi-layer die to overcome 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 chal- lenge was to create a hybrid design that incorporates the benefits of layer overlapping, while reducing unnecessary complexity and making the technology more cost-affordable for customers. This was achieved by overlapping layers in each semi-deflector, using a single cone. The highly efficient design 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 finished product; reduced sensitivity to changes in viscosity; reduced sensitiv- ity 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 materials; low residence time; compact design and a low tolerance stack-up error factor, all resulting in improved concentricity. The 800 Series Hybrid extrusion tool greatly reduces stag- nation, because overlapping layers are more inherently balanced than single layers and also because each semi- deflector is “tuned to flush.” Conventional deflectors must simultaneously achieve a balance between flushing, balanc- ing and eliminating the weld line. There is less difference be- tween the slowest moving material and the fastest moving material in the deflector channels, thus making the viscosity more consistent in the deflector. Guill Tool & Engineering Co., Inc. www.guill.com SI Group, a leading global developer and manufacturer of performance additives, process solutions, pharmaceuticals and chemical intermediates, announced an agreement to sell the majority of its global industrial resin businesses and its Brazilian specialty business to ASK Chemicals, a portfolio company of private equity firm, Rhône Group, LLC. The transaction includes SI Group’s industrial resins products and associated manufacturing sites in Rio Claro, Brazil; Ranjangaon, India; and Johannesburg and Durban, South Africa, as well as li- censed technology andmultiple tolling agreements globally. ASK Chemicals, headquartered in Hilden, Germany, is amarket leader in the foundry materials sector and manufactures binders, coat- ings, feeders, filters and release agents, as well as metallurgical products including inoculants, inoculationwires andmaster alloys for iron casting. The deal is expected to close later this year. “While the industrial resins business has long been a part of the SI Group portfolio, the decision to sell this portion of the business affords us the opportunity to reshape our portfo- lio,” said David Bradley, President & CEO of SI Group. “The sale of this business provides proprietary technology and know-how in the industrial resins business to ASK while re- aligning our focus around performance additives.” SI Group will carve out related businesses at these four sites, including the manufacture of global rubber & adhesives and oilfield products, as well as foundry products in Brazil, and will operate tolling agreements with ASK.
