SHOW PREVIEW | NPE 2018
2013, we have sold more than 40 models.” The company says that its KMD 73 K/P – which will be seen at the show – has high output, robust machine quality and high pressure stability. These are ideal properties for window profile production, it says. The process concept makes the series very
process-reliable, and very flexible for using various formulations. The optional bimetallic lining of the barrel, paired with a tungsten carbide welded screw – a requirement of the North American market – also makes it suitable for use in pipe extrusion. Also at NPE, the company will show the calibra-

extruders and machine builders: n It only takes half turn of the Cam Lock to remove and install the deflector and tip; n No fastening hardware is required; and, n Tooling retainers provide gum space adjustment; The die head is suitable for high- and low-vol- ume applications, which are accommodated with the changing of just one component. A family of crosshead designs is available and users can specify the ‘calibre’ (that is, the maximum die internal diameter) A vacuum chamber and kit for assembly and disassembly are included with the unit. Optional keyed tooling capability offers machine designers and end users quick orientation, so the overall unit design enables faster disassembly, proper cleaning and restart, allowing the line to become more profitable, more quickly, says Guill. �

KraussMaffei Berstorff will highlight its solutions for the construction industry at this year’s NPE – in- cluding conical twin-screw extruders for profile production and its QuickSwitch technology for fast diameter changes during pipe production For example, the KMD 73 K/P conical twin-
screw extruder demonstrates performance and flexibility. The QuickSwitch calibration basket up to 500mm stands as an example for a high degree of automation. “We are seeing high demand for conical profile machines that can be used both as main extruders and as co-extruders, especially in North America,” said Matthias Sieverding, president of extrusion technology at KraussMaffei. “Since introducing the conical extruder series to the American market in

tion basket of its QuickSwitch system. The exhibit demonstrates the effective diameter range from around 11 to 20in (280–500mm). The system is of particular interest for large pipe dimensions, because when a change is made to another dimension, the low quantity of waste has a positive impact on material costs. All process parameters can be set exactly, stored in the control system and called up again at any time. The company will also show its KM-VT 250/1/6 vacuum tank. Its integrated vacuum control and frequency-controlled pumps, which are fully integrated into the C6 line control system, provide for optimum activation, energy savings and uniform product quality, says the company. �

Maag will use NPE to showcase a variety of its products and processes. Its Extrex X6 class gear pump delivers volumetric
efficiency at high counter pressures and with the lowest amount of shear stress, it says. This results in a reliable and gentle transfer, boosting and meter- ing for a wide range of thermoplastic polymers, with no adverse effects on product quality. At the same time, its FSC plate screen changer
for extrusion processes is equipped with a pres- sure-adaptive sealing system that allows the required sealing forces to be adjusted to the actual melt pressure automatically. Their solid and robust construction, available in all sizes and designs, ensures a reliable and leak-free filtration of molten polymers. Its new extrusion cart has a space-saving move- able tripod design, which reduces inline footprint compared to four-wheel designs. The modular system allows for one size cart to handle the four most common size extrusion pump models for 3.5, 4.5 and 6in extrusion lines. With a simple adapter plate change, the original cart can handle a larger pump or gearbox, without replacing the cart should
