For many machine types, we supply the mold with the highest cavitation, thereby enabling optimum preform output. For the Husky HyPET machine, we offer an upgrade set for 33% more preforms, without refitting on the machine! • 60 cavities for Netstal PETline 2000 • 96 cavities for Husky HyPET 300, • 112 cavities for KraussMaffei 350 Engineering made in Germany 128 for HyPET 400 Patent pending: MHT cool MAX ® post mold cooling How to make millions a day Sumitomo (SHI) Demag presented North America with El-Exis SP, a machine that is capable of producing over three million caps a day, every day, with energy efficiency The main attraction at Sumitomo (SHI) Demag’s stand at NPE was a series of two live demonstrations of its El- Exis SP (for Speed Performance) 450/920-3000 moulding machine, which produced a ‘waterfall’ of over 150,000 bottle caps in an hour. The 500t (US) machine, which was making its first appearance in North America, was moulding 1g HDPE water bottle caps in a 96-cavity Schottli AG hotrunner, in 2.3s cycles. The actual production rate of 150,260 caps/h is equivalent to output of 3,606,260 over a 24h period. The demonstration also included an IMDVista vision inspection system, which checked the parts’ inner and outer diameters, seal area and tamper evident band. The El-Exis SP is available in model sizes ranging from 165 to 825t (US). The company says that it has been designed for high-speed production of applications such as thin-walled food packaging, closures for beverages, cartridges, plant pots and buckets. The hybrid machine is claimed to provide speed with performance through the use of ultra-high-speed injection by hydraulic accumula- tor and servo-valve, along with an energy-efficient electric screw drive designed to maximise plasticizing capacity and melt homogeneity. A clamping unit with AC servo drive and hydrostatic transmission provides quick mould opening and closing, with low energy usage. The machine features a number of developments over its predeces- sors. It is designed to be up to 30% more energy-efficient than other high- speed hybrids and offers an increase in injection speed of up to 30% over Cumitomo’s El-Exis S model. The company says that it can achieve up to 1,000mm/sec, depending on configuration and can accelerate from standstill to 800mm/sec in 25 mil- liseconds. A position-regulated servo valve, combined with a high-resolution path measuring system, has been created to support fast and precise transfer from injection to hold pres- sure. The machine’s new NC5 Plus control system has been redesigned and features a number of proprietary functions for high-speed operation and efficient energy use. The 330 to 500 US ton models offer an expanded opening stroke, in order to meet requirements for moulding deeper containers, such as buckets. Sumitomo manufactures a range of high-precision IM machines for various applications. Its all-electric platform extends from eight to 606 US tons, including micro to mid- sized, high-speed, high-duty, vertical, insert, high-speed multi-shot and disc moulding machine series. It produces ultra-high-speed hybrid machines for packaging and other thin-wall applications. www.sumitomo-shi-demag.com
