PETpla.net Insider 10 / 2010

TRADE SHOW PREVIEW 62 PET planet insider Vol. 11 No. 10/10 www.petpla.net Thin-walled preform claims shorter cycle-time and energy saving Swiss company Hofstetter will be showing its latest devel- opment in the field of thin-wall. It will be demonstrating a PET mould with 60 cavities at the K fair, which features an updated design that is claimed to offer improved energy efficiency and cost-effectiveness. Operated on a 200t moulding machine plat- form, this new generation of Hofstetter’s moulds is also delivered with OHXtreme coating. The company has been applying this coating for eight years and says that it delivers increased wear resistance in assembly group components. The original base preform was a 12.5g - 0.5l Bague 30/25. By analysing and rede- signing every detail of it, the developers in Uznach, Switzerland have managed to achieve a weight reduction in the region of 1.65g. The main factors contributing to this cut in weight are a spe- cial, Hofstetter-designed neck; the ‘Cappello’ contour at the base and a market-leading level of preform wall thickness. In achieving these advances, Hofstetter says that it has drawn on its 40 years’ experience in the production of moulds for thin-walled packag- ing articles. The company also mentions that all the redesigned, weight-reducing components are already present in moulds now running at various customer operations. Hofstetter presents its redesigned mould as a step forward in the ongoing drive for shorter cycle times, while helping to reduce the associated high wear of mould parts. The new product is also claimed to reduce energy use and resources consumption in PET bottle production. As well as its new mould and preform design, Hofstetter will also be showing a new cube mould for the production of tubes with integrated moulded lid and in-mould-labelling. This system has been developed in cooperation with Engel and Beck. www.hofstetter.ch Hofstetter AG Hall 1 Booth A40 Starlinger & Co GmbH Hall 9 Booth D21 Recycling technology Starlinger Recycling Technology will be exhibiting three recycling lines and new developments in its recoStar line, which is designed for recycling of PE, PP, PA, PS, PET and other plastics. A recoSTAR universal 65 VAC with an output of up to 200kg/h will be in operation twice a day, processing PP sack fabric. This machine’s heavy-duty sin- gle-shaft cutter, arranged parallel to the extruder, enables it to process films and materials such as tapes, fibres and start-up lumps. A new feeder system means that ground material and granulate can both be processed, without an additional dosing unit. The recoStar basic 85 with an output of 450kg/h will be demonstrated on stand B47 in hall 16. It can be used for all polyolefins, technical plastics and foamed materi- als. It is equipped with an agglomerator for predrying and compacting. Starlinger says that its recoStarPET iV technology yields recycled PET with the same properties as virgin material and decontamination values which allow direct food contact. The company’s SSP (solid state polycondensation) reactor series now includes a 15,000l model and a flake-only solu- tion. Other models include the recoStar direct recycler, which processes pre-ground and dry materials, and the recoStar compact, which is suitable for recycling polyolefin films either off-line or in-line. www.recycling.starlinger.com Efficient and economic recycling Austrian specialist company Erema will use the K Show to premier its new TVEplus recy- cling system. New developments include enhancement of degassing and homogenisation performance, as well as downstream components said to improve maintenance and cleaning. The stand will feature tailor-made systems for bottle-to-bottle-PET recycling systems and inline technologies for the direct production of materials from PET bottle flake. Erema says that its TVEplus technology facilitates the processing of even extremely difficult waste materials in a single pass. Vacurema technology enables processing of rPET that is suitable for food contact. Its recycling systems all feature the ecoSAVE technology introduced in 2010, claimed to reduce energy consump- tion by a further 10%. Erema subsidiary 3S, of Roitham, Austria, will be presenting a new system for measuring wear on extruder cylinders. Erema Hall 9 Booth C05
