Extrusion Asia Edition 3-2016

在工艺技术方面全面进行了重新设计，较长的预热区和经 过优化的螺杆设计可实现更高的挤出产量。同时，新的几 何结构可保证加工过程中机械运动产生的剪切热与输入的 热能实现最佳平衡，从而实现PVC类材料的更稳定地加 工。新设计还可以减小机器磨损，同时保证仅采用一种螺 杆结构即可以加工多种不同的材料混配料。 近年来，挤出加工的众多终端制品几何结构越来越复 杂，壁厚则越来越薄，模头需要承受的背压也越来越 高。conEX NG挤出机结构坚固，可以承受高达520 bar的 模头背压。这一新的锥形双螺杆挤出机还能满足共挤解决 方案不断提高的需求。有几种节省空间的款式或底座设计 可选。由于改进了高度和倾角调节装置，能够极佳地适应 各种共挤加工的标准挤出机需求。 全新设计的conEX NG的其他优点包括极小的占地空 间、高性价比，和极低能耗。因此，conEX NG挤出机能 够与巴顿菲尔辛辛那提的多种机器完美匹配，其中包括适 用于管材、型材、热成型片材和造粒的各种挤出机。 27 Extrusion Asia Edition 3/2016 battenfeld-cincinnati 32547 Bad Oeynhausen, Germany 1230 Vienna, Austria www.battenfeld-cincinnati.com conEX NG series compared to its own proven konos and conEX predecessor series, but also compared to extruders offered by its competitors, battenfeld-cincinnati has completely re- designed its conical extruders in terms of process technology. A longer pre-heating zone and an optimized screw design pro- vide 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 materi- al 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 result- ing 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 solu- tions. It is available with several different space saver or pede- stal designs and can be optimally adapted to every basic extru- der, thanks to improved height and tilt adjustment facilities. Further advantages of the completely revised conEX NG are a re- duced 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.
