production system, which processed 100% post-consumer recycled resin, producing a 12.1 g preform on a 96-cavity mould and running a 6.2 s cycle time.
Also debuting at K2019 was NexPET,
Husky’s flexible, lower cavitation system and mould for the middle output and multiple package market. Enabling the highest levels of preform quality at the lowest total cost to produce, NexPET is engi- neered to reduce the initial system invest-

technology. The company says that this is the first product of a new series of faster machines with improvements in precision and speed of injection. The operator interface is also optimised through a new control panel – the new HP series has been designed to pay particular attention to integration/ interconnection from an IIoT perspective. The machine shown at K2019 was a 450-tonne eK- W45HP/2200, with electric plasticisation and injection under accumulator, controlled by a double servo Moog valve and closed loop control. The special screw is designed to favour MuCell microcellular foam technology, able to reduce the amount of raw material on the product and the cycle time, without affecting aesthetic qualities. The company says that the machine is dedicated
to packaging, a sector that requires – in addition to energy savings that only electric or hybrid ma- chines can offer – even higher performance in terms of speed and accuracy. For this reason, the HP series has movements with direct torque motors on the clamping and plasticisation units, directly coupled to the toggle and screw rotation move- ments, without the use of belts or gear reducers. The new injection unit features a double servo Moog valve and electric plasticising for higher speed and precision. Husky introduced a range of new, flexible,
versatile PET preform moulding solutions at K2019 to satisfy customers’ increasingly diverse applica- tion and production needs. The new HyPET 5e systems platform is the foundation for a versatile, energy efficient family of PET preform moulding solutions capable of handling diverse output and performance needs. The HyPET 5e core system is an energy efficient platform, offering a versatile solution for standard preform designs and is upgradeable to address different business needs. The HyPET 5e+ is an evolution of the core platform and includes an upgraded options package to accommodate higher performance and production needs. In addition at K2019, Husky demonstrated the HyPET HPP5e, the company’s highest level

ment and future tooling costs – making customers more competitive to capture market growth. Husky displayed a 48-cavity NexPET mould, which is designed to be part of a complete NexPET system. (Also see Injection World November-December 2019 issue for more on Husky’s K2019 exhibits.) Negri Bossi has developed the Nova eT
range, aimed at the packaging, closure, medical and optical moulding sectors, being precise, efficient and fast. The Nova eT range runs from 50 to 350 tonnes clamping force and features the Smart Flex-2 clamp units that are specifically designed for electric actuation and reduced dry-cycle times. The whole range features gener- ous tie bar spacing, high injection speeds and the Tactum multi-touch controller, with its scroll, zoom and swipe capability. At K2019, a Nova e130T machine, fitted with a 40 mm barrier screw, ran a packaging mould manufactured by Molmasa, based in Spain. This demonstrated a new method for producing high-quality plastic blown bottles directly from the injection moulding machine. The solution offers a compact and reliable moulding system based on a horizontal injection moulding machine, coupled with simple and fast start-up, plus high quality of the final product.
