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.

Thermoplastic compounds with integrated electrical conductivity offer a potential solution to resolve EMI, EMS and electrostatic discharge challenges. These thermoplastic materials can deliver the appropriate level of electromagnetic shielding for electronics, while providing freedom to design complex geometries and opportunities to streamline processing by avoiding secondary operations.

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.

For Heavy-Duty Structural Components 

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.

As expected, the K 2019 displayed a wide range of machine technology and complete system solutions for plastics recycling. At least since the trade fair in Düsseldorf, Germany, it has become obvious that industry today can offer solutions for closing the plastic cycle.

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.

Evolution of Melt Filtration 

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.

The Barlog Group, with its companies Barlog Plastics GmbH, Overath and Bahsys GmbH, Overath, Germany, showcases a wide range of compounds for the mobility of tomorrow under the brand name Kebablend. These materials include thermally conductive plastics for thermal management of batteries in electric vehicles and magnetically soft injection molding materials for magnetic flow guidance, such as for contactless energy transfer. Barlog will also exhibit new compounds for electromagnetic shielding and a wide range of lightweight construction 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.

Attention to Detail

The manufacturers of machines and systems for plastics compounding are expanding proven series with new sizes and optimizing existing technology. Their main focus is on scale-ups between the systems. Despite highly customized special solutions, modular design enables integration into existing system technology.

The Formulation Is Not Everything

Munich-based mechanical engineering group KraussMaffei is repositioning itself and uniting all divisions under a single brand. At a time of accelerated technological change, the company is increasing its efforts to develop new products for digital solutions and new business models – and that includes plastics recycling.

Moving with the Times

Often pure plastic materials are not able to fulfill the increasing demands of plastic component. It is therefore necessary to adapt the properties of the plastics by adding other polymers or additives.
