KraussMaffei Berstorff to present a new laboratory and pilot system Schaumtandex ZE 40 / KE 90 at K 2013

Schaumtandex ZE 40 / KE 90 is a unique overall machine concept for developing and optimizing foaming processes

– Unique overall machine concept comprising a twin-screw extruder and a single-screw extruder for physical foaming of plastics.

– Lower energy consumption during melt cooling

– New performance category with maximum user-friendliness

– Appearance at the K 2013 trade show under the motto "Trendgineering"

(Hanover, August 14, 2013) KraussMaffei Berstorff will present a new member of its proven premium quality Schaumtandex series at K 2013 in Düsseldorf (October 16 to 23, 2013, Hall 15, Booth B27 / C24 / C27 / D24). The new Schaumtandex ZE 40 / KE 90 is a unique overall machine concept for developing and optimizing foaming processes.

Modular design permits processing of different raw materials

"Due to their high consumption of raw materials and energy, existing production machines are not economical for testing new processes or modifying process parameters," said Hilmar Heithorst, Divisional Manager Sheet and Foam Extrusion Lines at KraussMaffei Berstorff. "Even at low speeds when the test results can only be transferred to a limited extent, our production machine quickly consumes a few hundred kilograms of material," added Heithorst. The advantages of the new machines for customers can be seen precisely here. For example, the melting extruder - a ZE 40 UTXi twin-screw extruder - can be individually configured through the modular design of barrels and screws in order to process formulations with up to 10 different components. With regard to melting, the modular process concept of the ZE 40 UTXi offers ideal conditions for processing all standard plastics and numerous high-temperature plastics up to a maximum temperature of 350°C. Liquid, environmentally-friendly propellants are injected directly into the processing zone via injection nozzles and are mixed homogeneously in the plastic melt. Thanks to the C clamp housing connections and the compact design, the processing unit in the ZE 40 UTXi can be very easily converted in order to change the formulation.

Lower energy consumption during melt cooling

The specially designed KE 90 single-screw extruder for melt cooling cools the melt containing propellants down to a temperature just above the solidification point. Active melt sealing prevents the propellants from leaking into the gearbox. The special geometry of the screw ensures optimum melt cooling through modern calculation and simulation methods at low drive power. Energy consumption is reduced by between 30 and 40 percent. "Melting and cooling extruders are optimally coordinated to optimize the cooling effect and quality, even with maximum output, high propellant content, or sophisticated formulations," said Heithorst.

New performance category with maximum user-friendliness
The Schaumtandex machine is equipped with a control cabinet and a 19" monitor as standard features. All control functions can be triggered by simply pressing a button. The entire operating concept is intuitively designed and is easy to understand. The large monitor provides a total overview of the extrusion process and the machine functions.

The easy operation and robust technology of both the Schaumtandex ZE 40 / KE 90 machine and the smaller ZE 30 / KE 90 ensure production stability and genuine downscaling of production machines with all technical features.
