Extrusion line for tiny technical profiles

The benefits of the standardized techBEX complete line concept can be summed up under the motto "quality meets cost-efficiency" according to battenfeld-cincinnati. They are said to be a perfect example of high-quality manufacturing made in Europe, available at an attractive price and with short delivery times. techBEX lines cater particularly to companies with a wide product range and small production lots.

battenfeld-cincinnati has designed its techBEX lines so that they can handle a wide variety of applications with a high degree of standardization. This means that they are equally suitable for producing hollow profiles from resins including ABS, PS, PA, PC, PMMA, polyolefin or PVC for the building, furniture and automotive sectors and for making sealing profiles from thermoplastic elastomers as well as small pipes up to 63 mm in diameter. The high degree of standardization not only makes the attractive price and short delivery times possible, but also fosters extremely easy operation thanks to among other factors a reduced number of interfaces.

The individual components of techBEX lines are an extruder from the successful alpha series and the techBEX extrusion downstream equipment package. alpha single-screw extruders are available with screw diameters of 45, 60 or 75 mm and with either smooth or grooved feed zones. All extruders feature high screw torque and a wide processing window. A choice of optimized screw geometries ensures enormous flexibility regarding the types of polymers to be processed, and the pft power feed technology of the 28 or 30 L/D screws ensures reliable specific outputs. The extruder concept is rounded off by energy-efficient AC drives. For dry blend processing, the conical twin-screw extruder models Konos 38 and Konos 50 can also be used.

The downstream equipment package includes a calibrating table from the CT series with a length of either 2.5 or 3 m, a B 100 E belt haul-off, an SP 50E cutting saw and a PA 150/3m tilting table. The calibration table can easily be adjusted manually in lateral and longitudinal directions as well as in height. Thanks to its C fastening rails, it can be adapted to a variety of dies. It comes with a central water tank and a central water and vacuum distributor and ensures a stable vacuum thanks to its powerful vacuum pumps.

The B 100 E belt haul-off with its separate AC drive for each haul-off transport belt and length measurement device to trigger the cutting saw ensures smooth, gentle haul-off for the profiles. The cutting saw powered with a servo motor delivers precise cuts and is easy to operate, thanks to its own control system. It also provides easy access to the saw blade to facilitate maintenance. The special features of the tilting table include two pneumatic cylinders and the option to combine two 3 m tilting tables into one with a total length of 6 m.

The downstream equipment package is delivered completely pre-assembled, including electric wiring, so that it can be started up immediately on site. Both the techBEX downstream package and the alpha extruders are designed to function as parts of the complete line, but they can also be used as flexible individual units.-[email protected]
