Husky’s next generation HyPET boasts 12% higher productivity

Canadian firm Husky Injection Molding Systems has launched its next generation HyPET HPP5 preform moulding system. Building upon the proven technology of the HyPET platform, enhancements have been made that make it capable of delivering the lowest total cost to produce while providing exceptional preform quality, says the firm. These enhancements allow for up to 12% productivity improvement over the previous generation system and are complemented by all new levels of production flexibility, tooling compatibility and the industry’s first integrated solution for extended mould life.

“Husky is committed to offering customers the best return on their investments through continuous innovation. When developing our new HyPET HPP5 system, we listened to what our customers were telling us and with that feedback in mind designed a system that would help them run a more competitive injection moulding operation,” said Robert Domodossola, Husky’s Vice President of Engineering and Business Development. “HyPET HPP5 is the result of meaningful technology refinements to many areas that combined offer the most complete and integrated injection moulding system for preform manufacturing on the market today.”

Designed to satisfy the needs of customers with a large installed base of tooling, HyPET HPP5 offers customers the ability to utilise moulds from previous generation products. Simplified cross-generation mould compatibility packages make upgrading equipment easier and help to preserve valuable floor space, while allowing customers to manufacture a complete product range. In addition, a combination of technical solutions offer enhanced production flexibility, which makes the replacement of legacy assets more viable.

A key enhancement to the system is the addition of the industry’s first integrated solution for extended mould life, which helps to significantly improve performance and reduce maintenance costs. Benefits include a 60% increase between required mould maintenance intervals and extended tool life up to 10 million cycles without excessive wear or flash. Sensors ensure correct mould installation and detect misalignment between mold halves during operation. If misalignment is detected, sensors signal the operator through the Polaris HMI and provide specific instructions to correct misalignment, allowing the vertical position of the cold half to be adjusted and the mould aligned without the use of a crane. Additional features to reduce maintenance and machine downtime include an improved procedure to align neck rings to the cavity plate and specialised anti-wear coatings that extend greasing intervals up to 120,000 cycles.

Furthermore, the CoolPik dehumidification unit, standard on the new system, has also been improved by replacing the desiccant wheel dehumidification and air to water heat exchanger with refrigerator combined cooling and dehumidification. It thus, offers air cooling and dehumidification efficiency improvements that can yield a more than 20% reduction in energy consumption. For carbonated soft drink preform applications, when combined with better melt control and other advantages, a cycle time improvement of up to 3% can be achieved.

Other features are that the software and hardware have been designed to work together seamlessly. The system has undergone considerable improvements to streamline operation, including upgrades to increase automation and simplify controls. The Polaris HMI has been redesigned with a 19-inch full colour LCD display, more intuitive layout for easier access to screens, and the ability to monitor and control auxiliaries. Operating software and menu screens have also been enhanced to simplify start-up and logic has been provided to act on the auxiliary feedback and alarms during operation. The Altanium temperature controller is now also fully integrated and can be controlled using the Polaris HMI. Further simplifying start-up and improving ease of use is Husky’s patented intelligent Mold ID technology, which provides information on mould maintenance, process set-up and operation for each start-up.
