Extrusion International 2-2019

22 Extrusion International 2/2019 INDUSTRY NEWS Battery Separator Film Production The EV offensive of the European andGerman automobile in- dustry will soon lead to production plants for batteries and the necessary supply chain in Europe and Germany. Battery separa- tors are an important element for function and safety.Manufac- turing demands highest quality and efficiency. Moreover pos- sible investors count on sustainability. The industrial solutions of Brückner Maschinenbau for the pro- duction of battery separator films are based on extensive inter- nal R&D. For the Battery Show Europe 2019, the company pre- sented various in-house developed stretching technologies for all three common manufacturing methods: wet, semi-dry and dry. Brückner’s portfolio comprises technical solutions for both machine components and complete production lines. Main highlights: • Patented film transportation system with relax chain for low- shrink separator films • Simultaneous stretching process for highest quality require- ments • Line concepts with special focus on environment friendly and sustainable processes Sales and marketing director Karl Zimmermann says: „Because of our nowmore than 20 positive references from leading inter- national battery separator producers we see best chances for us to take part from the beginning, when battery production and separator filmmanufacturing will be settled in Europe and Ger- many. Production efficiency, consistently high film quality and the further development of environmental standards are our core issues.“ Brückner Maschinenbau GmbH & Co. KG www.brueckner.com Latetst Battery Separator Film Technology Guill Tool & Engineering www.guill.com Co-Extrusion Crosshead for Irrigation Tubing 30mm (1.18”). The Series 824 design allows the emitter inser- tion tool to pass completely through the crosshead ID. Gum space adjustment is performed with die nut rotation, while the Guill 2-stage clamping mechanism allows easier concentricity adjustment. Quick-change tooling and a tool kit for disassembly and re-assembly are provided with the unit. Bill Conley, sales manager for Guill, comments: “On this project, the customer challenged us with an application that required precise placement and bonding of preformed emitters within the extruded tubing without melting them in the crosshead. It was also necessary to process either a low-cost ABA layer con- struction or single-layer construction within the same unit.” With the Series 824, the customer realized cost reductions, bet- ter quality, less scrap andmore uptime in their process. TheGuill cool-tube design prevented the emitter from melting in the head and the overall unit mechanics allowed more rapid and easier changeover from a co-extrusion to a single layer. On this project, Guill also supplied the customer the company’s extrusion tool cart, which facilitates easy alignment and tool changes. The removable cart swing gates stay free from accu- mulated process fluids, while the adjustable height means the cart is compatible with virtually any extruder model. Thermal isolation in the design keeps heat in the head, not the cart. Guill Tool introduced Series 824, a co-extrusion crosshead de- signed for irrigation tubing with an emitter tool. Manufactured from stainless steel, this new crosshead features balanced flow design with spiral technology that improves flow characteristics at all extruder speeds. Dual feed ports provide concentric com- pound flow, while the splits flow fromone extruder to feed the inside and outside layers via a manifold assembly. Series 824 is adaptable to all popular extruders on the market currently. Capacities include a max. die ID of 1.875”, max. core OD of 1.250”, max. tip OD of 1.500” and max. emitter tool OD of
