The new extruders and extrusion components from battenfeld-cincinnati, Bad Oeynhausen/Vienna, which were presented at the K, furnished direct proof of their efficiency. During an Open House event staged simultaneously at the Kempen facility, the machine manufacturer presented three extrusion lines in operation to some 600 visitors on two days: a profile extrusion line, a pipe extrusion line and a film extrusion line.
“We are more than satisfied with both events – the K and the Open House”, says Jürgen Arnold, CEO of battenfeld-cincinnati. “600 visitors at our Open House and twice as many actual negotiations with customers at the K, that is definitely a complete success.” The very positive response to the new brand of battenfeld-cincinnati was not only reflected in the numerous conversations with decision-makers from the industry. “Order entry at the K also considerably exceeded our expectations, and numerous new projects were started as well.”
In the extruders and extruder components presented at the K, the know-how from Bad Oeynhausen and that from Vienna were combined for the first time. The focus in the new developments was invariably on meeting the customers’ demand for energy-efficient, high-performance solutions. All three complete lines presented at the Open House met this demand in a special way.
The Packaging Division presented a 3-layer PET film extrusion line equipped with the BC 1-90-34 D PWE 140 extruder, which is specially laid out for direct processing of PET flakes without pre-drying. With an output of 600 kg/h, an r-PET resin with an initial moisture content of more than 1,000 ppm was processed into the middle layer of the film. Thanks to the use of virgin material for the outer layers, which were co-extruded with an output of 100 kg/h, this PET film is suitable for any food packaging application. The special process technology characteristics of the main extruder lie in the combination of a conventional single schrew with a modified planetary roller unit, which provides the degassing performance that is necessary for an initial moisture content of more than 1,000 ppm. Another highlight of this line was the polishing stack, which is perfectly geared to the high line output. Quite apart from that, polishing stacks from battenfeld-cincinnati are designed for easy operation and maintenance.
The Infrastructure Division presented an extrusion line in Kempen with variable parameter settings for three-layer PO pipes with diameters ranging from 125 to 250 mm, with a maximum output of up to 1,200 kg/h. Apart from the extruders, the highlights of this line include the innovative Efficient Air Cooling (EAC) system and the patented, electrically adjustable calibrating unit for different pipe diameters. EAC is a part of greenpipe, the new overall concept of battenfeld-cincinnati, which contributes to pipe production with extremely low energy and water consumption with several features developed in various sizes. The main extruder used was the size 75 model of the new single-screw solEX series, which was presented to the public for the first time. This new extruder series enables above-average output with low melt temperature. For instance, the solEX 75-40D on display reaches an output of up to 1,200 kg/h in HDPE processing. Consequently, these machines, which are available in five sizes with screw diameters of 45, 60, 75, 90 and 120 mm, are ideally suited for high-speed extrusion of PP-b and HDPE pipes.
The Construction Division showed a twin-strand extrusion line for PVC window main profile production with an output of 420 kg/h. twinEX is the name of this new twin-screw extruder series, from which a twinEX 93-34 model was integrated in the line on display. Thanks to their 34 D processing length, the four models of this parallel, counter-rotating twin-screw extruder series reach impressive outputs ranging from 100 to 1,000 kg/h.
The main feature accounting for this increase in performance is the completely revised processing unit. In combination with the most powerful drive unit currently available, powered by an AC motor, the outputs as mentioned above have become possible. The drive unit is kept very compact thanks to its U-shaped design, so that the extruder does not require more space in spite of its longer processing unit.
With the three lines presented and the individual components shown at the K, battenfeld-cincinnati demonstrated in an impressive way that the solutions that have been jointly developed meet the demand for high efficiency and performance in every respect.
