Husky raises the productivity bar for closures and showcases technology for faster PET mold changeover

Husky Injection Molding Systems today announced that at Chinaplas 2008 it is demonstrating innovative new solutions that will help customers be more competitive by improving cost-effectiveness and productivity. Husky is unveiling two systems at the show (Shanghai New International Expo Centre, Hall E2, F01): a HyPET 90 preform system with Flex Mold and a Hylectric 400 for lightweight closures. HyPET 90 preform system – flexible and cost-effective with Flex Mold The HyPET 90 is a flexible and cost-effective PET system featuring Flex Mold, an innovative, modular, low cavitation PET preform mold. Chinaplas 2008 is the first time Husky is demonstrating this new technology since announcing it at K2007 in Dusseldorf. Flex Mold is ideal for customers who use the same machine for multiple applications and therefore need to change molds with minimal downtime. This is particularly important for converters that are producing smaller volumes of preforms – in the range of 5-30 million per year. With Flex Mold, the bodies of the cavities can be changed while the gate pad remains in the mold. The unique design of the mold eliminates the need to cool down and reheat the hot runner during a part changeover, greatly reducing system downtime. Mold change times can be reduced to as little as a quarter of the time taken for a conventional mold. System details are as follows: Machine         HyPET90 RS 45/45Mold 8            cavity Flex Mold Part weight   16.1 grams Resin             PET Cycle time     9 seconds Auxiliaries     Integrated with new Polaris interface to Piovan (resin dryer, mold dehumidifier and soft drop) Hylectric 400 closure system – improved productivity and lighter, safer parts The Hylectric 400 is the industry’s highest output system for finished water closures, producing in excess of 1 900 closures per minute. The Chinaplas system is producing closures that combine Corvaglia’s patent pending Break Then Leak (BTL) technology and Husky’s lightweighting capabilities. As a result, the application offers both superior tamper evidence protection and reduced part weight. System details are as follows: Machine          H400 RS95/80 Mold                 96 cavity Corvaglia closure mold Hot runner      96-drop Ultra 750 HT-S6 Part weight    1.7 grams Resin              HDPE Cycle time      2.9 seconds Auxiliaries      Piovan dehumidifier, Greenbox cap cooler, IMD inspection sorter system, GIMA packing automationHusky is also showcasing the following at Chinaplas 2008:  The latest hot runner technologies, including the new “ECO hot runner”, an entry level hot runner system for applications requiring injection pressure of up to 2 000 bar (29 009 psi) HyMET, Husky’s unique metal molding technology that enables companies to produce lightweight, low cost, high quality parts for the consumer electronics and automotive markets A range of manufacturing software and services that help customers achieve the lowest cost of operation in their injection molding facilities
