Bipolar plates are one of the key components of fuel cells and redox flow batteries. They consist of plastics compounds highly filled with electrically conductive materials. To save space, cut costs, and reduce weight, there is increasing demand for the production of thinner plates without compromising robustness and service life. This can be achieved using modified polymers. With a new technology, bipolar plate films based on these modified polymers can be processed as coils.

The quality of final products can be increased by using measurement technology for monitoring production processes. Interest in it is increasing especially for compounding. There are various existing methods of non-destructive testing that can also be used inline in the manufacturing process. The different methods are suitable for different applications: an overview of the current capabilities and limitations of the various inline methods.

The patent on the operating principle of the co-kneader was applied for three quarters of a century ago. Compared to other extruder technologies, it features a clearly higher mixing effect while it processes the raw materials gently. Current applications for its further development range from reactive, shear-sensitive plastics to the compounding of high-performance engineering plastics.

Thanks to its special working principle, the co-kneader fulfills top mixing requirements. Until now, however, its design could not be based on simulation. Systematic investigation together with analytical and numerical models overcome this hurdle and provide the basis for computer-aided optimization.

Starting immediately, ips Intelligent Pelletizing Solutions GmbH & Co. KG, Niedernberg, is also supplying systems for the production of long fiber-reinforced thermoplastics (LFT). For this, the company is delivering complete systems from a single source ¿ from planning through construction to commissioning ¿ just as for strand and underwater pelletizing systems.

The mechanical properties of plastic compounds are an important quality criterion. At present, however, they can only be determined by laboratory measurements with a time delay. Online measurement procedures during compounding save time and prevent errors during the production process. A research project shows how the impact strength and hardness of the compound strand can be measured online.

A Closed Recycling Cycle – Now!

Gels in plastic melts represent a high risk to the part quality. Large-area filters, together with depth filter media provides a remedy. In the development of the scalable 15-inch disk filters, Seebach GmbH, Vellmar, Germany, used in-house simulation software to assign pressure losses to individual assemblies, and make appropriate adjustments.

Coperion GmbH, Stuttgart, Germany, presented advances in twin-screw extruders at K 2019. According to the manufacturer, they are suitable for performing high-quality recycling on an industrial scale, e.g. for regranulating plastics such as HDPE, PP, ABS, PS and PVC for the manufacture of films, recycling of PET as well as upcycling of materials.

Paint bucket or A-pillar finisher? In our thoughts and attribution of value, packaging items and high-tech components often represent opposites. Yet the two can complement one another – when you look at used packaging as a valuable raw material. At the fair, KraussMaffei will be showing the concept for a closed material cycle and is making plastics processing sustainable through this.
