K 2019 Preview: Injection Molding Goes for the ‘Green’ : Plastics Technology

‘Circular Economy’ joins Industry 4.0 as common themes of injection molding exhibits in Düsseldorf. If you attended a major international plastics trade show in recent years, you were likely bombarded with messages that the future of plastics processing is “digitalization,” also known as Industry 4.0. That theme will continue in force at October’s K 2019 show, where numerous exhibitors will present their latest features and products for “smart machines, smart processes and smart service.”  But another overarching theme will claim pride of place at this year’s event—“Circular Economy,” which refers to the whole range of strategies for recycling and reuse of plastics waste, as well as design for recyclability. While this will be one of the dominant notes sounded at the show, other elements of sustainability, such as energy savings and lightweighting of plastics parts, will be heard frequently as well. How does injection molding relate to the idea of the Circular Economy? A number of exhibitors will endeavor to answer that question: •  Because variation in melt viscosity is one of the major challenges to molders of recycled plastics, Engel will show how its iQ weight control softwa...

Blow Molding at NPE2018: Blow Molding Systems Run the Full Spectrum at NPE : Plastics Technology

Machines for every process—shuttle, wheel, reciprocating-screw, accumulator-head, suction-blow, injection-blow, compression blow, and one- or two-stage stretch-blow molding—will be running in Orlando. There will be a host of new models, including electric and servo-hydraulic types. Among the new crop of electric machines is Bekum’s EBlow 407DL (double-sided, long-stroke) shuttle machine, to be shown with a special quick-mold-change upgrade (15 min without tools). Pet All Manufacturing is exhibiting for the first time its new ISBM-180E all-electric, four-station rotary one-stage PET stretch-blow machine with a 15-ton clamp and six to 10 cavities for containers from 10 to 100 ml. Jomar has extended servo-hydraulic drive to its three largest injection-blow machines, including this 135-tonner. Its Intellidrive system saves up to 50% of energy consumption and speeds dry cycles. Liberty injection-blow tooling system from R&D/Leverage is said to solve longstanding problems with setup, maintenance, and quality. Mini Hercules from Graham Engineering is a new small-shot (2.5 to 8 lb) accumulator-head machine that can perform color or material changes in 1 hr. S.T. Blow Moulding of Ita...
