PET products 44 PET planet insider Vol. 16 No. 09/15 www.petpla.net Stretching the limits of PET processing Cypet Technologies Ltd. of Nicosia, Cyprus, manu- facturer of single-stage PET processing machines has successfully produced on its Cypet K 28 machine a 50l flat-based container for the storage of liquids, powders or granular products. A 50l beer keg and a 35l conical-based container could be used as a fermenter for home brewing of beer. With the machine model Cypet K 53 it is possible pro- ducing up to 100l PET containers. Such containers can replace HDPE drums, especially for single-trip applica- tions, resulting in weight reduction with the corresponding substantial savings in raw material cost. Cypets technol- ogy uses one clamping unit for both: the injection moulds for moulding performs and as well as for the blow moulds for stretch-blowing the bottles or jars. By using a strong clamping unit with ample space to house large moulds for big PET containers, Cypet machines are stretching the limits of PET processing to 50l and beyond. With their capabilities for container height, up to 850mm, as well as container body diameter, up to 450mm, Cypet machines are able to provide the PET industry the opportunity into new applications for the bulk packaging of foodstuffs, bev- erages, cleaning products and chemicals. The machines capabilities are also usable for taller bottles with a less diameter for equivalent volume, resulting in increased strength, allowing to optimise bottle weight in applications like water dispenser bottles. Cypet has patented, designed, developed and com- mercialised a total of eight machine models ranging from 120t to 530t clamping force for the production of PET containers. Containers sizes from 50ml to 100l, with neck diameters of up to 220mm. Five of these machine models are based on servo-hydraulic technology for energy saving, while three are all-electric machine models, partic- ularly suitable for clean room production of pharmaceuti- cal or foodstuff containers. The Cypet machines are fitted as standard with an air regeneration system, recovering the high-pressure blowing air for re-use. www.cypet.eu Eco-sustainable solutions The Smi laboratories has led to the launch of the Ecobloc series featuring integrated systems of stretch- blowing, filling/capping and labelling of PET containers with capacity up to 3l. The Ecobloc systems is said to be compact because of the modular frame, the application technologies ensures the synchronisation between the dry environment of the stretch-blowing module and the wet environment of the filling/capping module. Suitable for bottling lines of still and carbonated drinks, milk and edible oil, Smi’s integrated system of the Ecobloc series offers to the end user for example the machine’s modular and compact structure, which brings together the stretch-blow moulding, filling and capping modules in a single block and allows to eliminate the connection belts between blow moulder and filler and even, except in rare cases, the bottle rinsing machine. With this type of system, there is a reduction of water consumption, electricity, man- agement and in maintenance care. The stretch-blow moulding module of Smi’s Ecobloc is equipped with an air recovery system (ARS), which recov- ers up to 40% of the high pressure compressed air used in the bottle production process to reuse it either during the pre-stretch blow moulding stage or in the machine’s utility systems. The Ecobloc reduces the risk of contamination of the bottles on their way from the blow moulder to the filler thanks to a star-star system enclosed inside a hollow joining cavity equipped with steel guards. The stretch-blow moulding, filling/capping modules integrated in an Ecobloc system are governed by a single automation and control system that allows the management of the system by one line operator through a simple and user-friendly man-machine interface. www.smigroup.it
