KraussMaffei Berstorff Opens its Doors in the U.S.

On May 15, 2014 the subsidiary of the KraussMaffei Group in the USA is opening its doors to customers. As part of this event, which has already become a tradition, KraussMaffei Berstorff is displaying the efficient production of two-layered PE pipes on a running extrusion line, which is equipped with the KM-RKW 34-250 IPC multi-layer pipe head and the KMG 81-40/R twin-screw extruder. Another focal point is the recycling of polystyrene with a twin-screw extruder.

The KM-RKW 34-250 IPC pipe head is designed with an outer-layer adapter. It produces PE pipes with a diameter of 114.3 mm and a wall thickness of 12.7 mm (4" SDR 9 IPS), which are provided with an outer layer of 2 mm that serves as a protective layer. Pipes of this kind are primarily used in drinking water applications when routing without a sand bed. The system guarantees additional cooling of the pipe from inside using ambient air, which is sucked through the pipe opposite the extrusion direction using a side channel compressor. The outputs are significantly increased (by a maximum of up to 60 percent), without having to extend the cooling section in the process.

In addition, the KME 75-36 B/R single-screw extruder can be seen as an exhibit. The extruders in this series are excellently suited particularly for processing the material mixes used especially in the USA (called salt and pepper mixtures = natural and masterbatch). Their process concept guarantees gentle melt processing and therefore optimum melt homogeneity as well as a perfect mixing of masterbatch.

Furthermore, KraussMaffei Berstorff is presenting an in-line color spec monitoring color measurement system specially for masterbatch manufacturing on a ZE 25 laboratory extruder. The system significantly reduces the downtimes of twin-screw extruders, because color matching is particularly fast and easy during compounding.
