CAPPING / CLOSURES 45 PET planet insider Vol. 12 No. 09/11 www.petpla.net With these optimisations and improvements, energy con- sumption in the Netstal range (based on the production of a PCO 1881 closure weighing 2.3g) can be compared as fol- lows: Compared with the Syn- Ergy range there is a saving of up to 13% with the Evos range and up to 40% with the Elion range, following identical pro- cess parameters (see table) Continuing reduction of clo- sure weight leads to increased output and an improvement in economic efficiency. The turning point became clear in 2009/10, when output could be signifi- cantly increased due to a sub- stantial reduction in cycle time (see graph). Competitive advantages for closure manufacturers in this highly cost-intensive applica- tion are significant. As well as higher output per m², lower electricity consumption is a core feature of economically efficient manufacturing. The lower costs of closure manufacture that can be achieved with the measures described above, together with further improvements in closure design, mould and automation performance, are becoming apparent in series production. Specialists from Netstal’s CAP Business Unit are in the very early phases of evaluat- ing customer requirements and needs and implementing them in complete, ready-to-use produc- tion lines. www.netstal.com (Data in kWh) Synergy Evos Elion Main Drive(s) 78 56.3 25 Screw Drive 23.5 25 25 Heaters Machine and Mould 24 27 27 Total 125.5 108.3 77 Sleevematic ES – the sensa- tionally saving-savvy system for super-elastic sleeves. www.krones.com PACK EXPO 2011 Las Vegas, 26 – 28 Sep.
