conEX NG: maximum productivity for global demand

At the booth of battenfeld-cincinnati, visitors can expect not one, but two premieres this year. In addition to the new solEX NG high-speed single screw extruder series, the machine manufacturer is also presenting a new conical twin screw extruder series. The conEX NG series, consist-ing of three models, fulfills all current demands of the global extrusion industry for the flexibility required to produce a wide range of different high-quality products at low cost.

As an extruder specialist with more than 50 years of experience, battenfeld-cincinnati is thoroughly familiar with the requirements of the market and the needs of its customers. With the new conEX NG, the machine manufacturer is launching a global machine which offers a robust, mechanically flexible drive train and an improved screw tempering system. Due to the identical mechanical design of the screw core, the latter can easily be adapted to different temperature control systems and consequently to different markets and end products. The machine also caters to the continuously increasing tool back pressures and is able to operate under a permanent process pressure of up to 520 bar.

In order to achieve significant improvements with the conEX NG series compared to its own proven konos and conEX predecessor series, but also compared to extruders offered by its com-petitors, battenfeld-cincinnati has completely re-designed its conical extruders in terms of process technology. A longer pre-heating zone and an optimized screw design provide higher outputs. At the same time, the geometry concept ensures a balance between mechanical energy input over shear and thermal energy input, which increases the bandwidth of PVC-based materials to be processed. This minimizes machine wear and simultaneously ensures that a great variety of material blends can be processed with just one screw configuration.

The sturdy mechanical machine structure enables the extruder to handle the high tool back pressures of up to 520 bar resulting from the more and more complex geometries and thinner wall thicknesses of the end products. The conEX NG is also the right answer to the increasing demand for co-extrusion solutions. It is available with several different space saver or pedestal designs and can be optimally adapted to every basic extruder, thanks to improved height and tilt adjustment facilities.

Further advantages of the completely revised conEX NG are a reduced footprint, high price performance ratio and lower energy consumption. In this way, conEX NG extruders fit perfectly into the wide range of machinery from battenfeld-cincinnati, in which suitable extruders for pipe, profile, thermoforming sheet and pelletizing applications can always be found.
