The company’s new Fractional Lobed Elements are designed to create turbulence in the melt flow without causing stagnation. They can replace conventional kneading blocks, completely removing any right-angled face to the melt flow. ❙

Sikora’s Purity Scanner reliably removes contaminants from pellet streams
with an optical system to identify pellets with metallic and organic impurities as small as 50 microns on the pellet surface or even fully contained within the pellet. Contaminated pellets are separated by air jets in order to ensure that they do not get into the extrusion process. The scanner is designed for a throughput of 500, 1,000 or 2,000 kg/hour and it can be integrated into existing feeding systems. It can handle neat poly- mers, compounds or masterbatches. ❙

Steer is
promoting the benefits of its
new generation of Fractional Lobed Ele- ments
Steer is launching its new generation of Fractional Lobed Elements which have been designed for improved reliability, reduced wear and increased uniformity of melting and mixing. Conven- tional kneading blocks are known for their ability to disperse, but can be too harsh for many applications, says Steer. Even relatively gentle right-handed kneading blocks present a perpendicular face to the flow causing melt stagnation and large pressure and shear peaks, it claims.
Materials testing
Atlas Materials Testing is showcasing two of its full-spectrum xenon instruments that enable users to test the weatherability of their products realistically under accelerated conditions. The Ci4000 Weather- Ometer features a new user interface along with innovative data acquisition software and an online specimen surface temperature measurement system. The Suntest XXL+ is a flatbed xenon exposure instru- ment featuring an extra large 3,000 cm2
for large components and three-dimensional parts ❙

88 COMPOUNDING WORLD | March 2015
Instron is showing its new Advanced Video Extensom- eter (AVE 2), designed for compliance with the ISO 527-2 and ASTM D638 testing standards. The AVE2 is a fully-integrated device that adapts to the normal fluctuations of environmental conditions in the labora- tory, such as thermal and lighting variations. Instron claims the AVE2 device is the only video
specimen tray
extensometer technology on the market to use a real-time 490 Hz data rate while also being able to provide 1 micron accuracy. ❙

Wittmann is showing its latest large gravimetric blender – the Gravimax G56 – designed for the mixing of up to six different components. Offering a blending volume of up to 5 kg, this new unit is said to provide the same control features, easy access and process reliability of the company’s smaller models. Dosing is carried out by pneumatically operated, wear-resistant metering valves with cylinders located outside of the material flow, which prevents material from bridging and makes the cleaning process easier. The new unit also includes an RTLS (Real Time Live
Scale) weighing unit that determines how often and for how long every metering valve must be activated, allowing a metering accuracy of ±0.1% to be main- tained. The SmartRegrind function automatically switches supply to prevent the processing
machine coming to a standstill if there is a lack of granulate. ❙

Zhang-Jiang Automation is showing its automatic systems for materials weighing and conveying. It offers complete systems for a wide range of plastics applica- tions, including compounding, PVC pipe production and wood-plastic composite (WPC) extrusion. Zhang-Jiang is located in Jiangsu, China, and is owned by Taiwan- based Pai-Ying. ❙
