ments that increase productivity, improve part quality and optimise energy efficiency, the HyperSync is a truly synchronised system, where all parts are designed to work together,” he says. A key element of the HyperSync production system is Husky’s eIMC in-mould closing technology. “This servo-driven technology allows for the safe overlapping of mould functions, providing precise, controlled closing of flip-top closures while still in the warm position,” Zhang says. “The speed of closing is carefully controlled, allow- ing for quick closing movements with precision. This ensures the fastest closing speed while maintaining the ideal force required and ensuring optimal part quality. The use of eIMC in-mould closing technology provides up to 20% increase in productivity, with nearly two seconds saved per cycle depending on the application.”
Energy efficiency Wittmann Battenfeld sees the main current trend in packaging as a move towards energy efficient electrical drive technology and faster cycling and more dynamic injection machines. It also reports growing demand for machines that can run in cleanroom conditions. These are the key design aims for its new EcoPower Xpress
machine, which was shown in a 400 tonne prototype form at K2016. In the EcoPower Xpress 400/1100+, Wittmann
Battenfeld says that it has developed a high-speed, all-electric machine model geared to the primary requirements of the packaging and thin wall industries. The highly dynamic servo drive technology used for injection and clamp movement on the EcoPower Xpress are designed to deliver fast movements and ultimate control accuracy together with extremely high energy efficiency. The EcoPower Xpress 400/1100+ is the first size of this machine series, which will be available from the autumn of this year as a range with clamping forces from 210 to 500 tonnes.
In-mould labelling is also being used more widely in injection moulded packaging production and was demonstrated at K2016 on the EcoPower Xpress model producing PP lids in an 8-cavity mould supplied by Greiner Packaging on a 4.7s cycle time. The automation system inserted the IML foils, removed the labeled lids, presented them to an integrated camera for quality inspection, then separated the good parts from rejects. Features of the system include a compact design and the facility for fast foil changeover. Packaging is not all lightweight disposables. KraussMaffei has been focusing its packaging developments,
