PREFORM PRODUCTION 21 PET planet insider Vol. 14 No. 12/13 tional cooling layout options, increase the degrees of freedom in preform design and can permit further reduc- tions to be made in the weight of the preform. Sensors ensure correct mould installation and detect misalignment between mould halves during opera- tion. They signal the operator through the Polaris HMI with specific instruc- tions to correct any detected misalign- ment, allowing the vertical position of the cold half to be adjusted and the mould realigned without the need to resort to a crane. The general industry change times for a cold half from the point when pro- duction is stopped to new tool installation is approxi- mately 4h or more. By way of an option, there is now the possibility of reducing the change time to 1h. This is made possible by hydrau- lic rapid clamping systems, a new hot runner design that allows the hot runner to remain hot, and special quick coupling systems for water supply. Additional features to reduce maintenance and cut downtime include an improved procedure for align- ing neck rings to the cavity plate, and specialised anti- wear coatings that extend greasing intervals up to 120,000 cycles. Performance and energy The CoolPik dehumidifica- tion unit, standard on HyPET HPP5 systems, now features refrigerator combined cooling and dehumidification, in place of desiccant wheel dehumidi- fication and air to water heat exchanger. These changes are claimed to offer reduction in unit energy consumption of more than 20%. In the case of CSD preform applications, when combined with better melt control and other advan- tages, a cycle time improve- ment of up to 3% can be achieved, according to Husky.

System The complete software and hard- ware system on the latest HPP5 has undergone improvements to stream- line operation, including upgrades to increase automation and simplify con- trols. The Polaris HMI has been rede- signed with a 19-inch full colour LCD display, with a more intuitive layout for easier access to screens, along with the ability to monitor and control auxiliaries. Operating software and menu screens have been improved to simplify start-up, and logic has been provided to act on the auxiliary feed- back and alarms during operation. The Altanium temperature control- ler is now fully integrated and can be controlled using the Polaris HMI. The HPP5 incorporates Husky’s patented intelligent Mold ID technology, which provides information on mould mainte- nance, process set-up and operation for each start-up. www.husky.co
