Pneumatic conveying of a raw material from the silo to the processing line does not sound like a very spectacular task. But in everyday routine, problems often occur. The manufacturer AZO is pinning its hopes on software that uses artificial intelligence to find the optimum operating point.

Prometheus Should Handle It

Infrared heating technology has become established as the standard in the processing of thermoplastic composite materials. The focus is on process control. On the one hand, it is important that the heating process is fast, on the other hand, the material must not be overheated. It is also important to achieve excellent temperature homogeneity. Simultaneous processing of blanks with different thicknesses is a particular challenge.

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.

In order to avoid bubble ruptures during the production of blown film, the velocity of the cooling air is often reduced. The use of air guiding systems (AGS) can prevent such bubble instability. A novel AGS was developed at IKV in Aachen, Germany, using iris diaphragms in order to increase the cooling efficiency of blown film extrusion and thus improve the productivity of an existing plant

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.

In the wake of the developments in processing methods, the technology of ancillary equipment is also making advances. The key drivers of the developments are cost savings from increasing the energy efficiency of dryers and greater precision in dosing equipment.

Closing a Gap

Many so-called “low carbon footprint technologies” are already available and could be utilized immediately in plastics processing. But what carbon reduction measures are not only environmentally effective? Using practical examples, gwk shows how the use of efficient temperature-control technology rapidly pays off economically, too.

The multi-stage regenerative impeller design of the new Conair HRG Series vacuum pumps is the key to developing deep vacuum power for conveying plastic pellets over long distances, while keeping noise levels comfortably low. An optional variable-frequency drive is available to save energy and enables the use of the new pump in Conair Wave Conveying systems.

Extrusion blow molding enables cost-effective production of hollow plastic articles with complex geometries and differing volumes. One disadvantage, however, is that blow-molded components often fail at the weld line. Variothermal temperature control can be utilized to significantly improve the quality of the weld line.

Besides custom-made automation solutions, there is also increasing global demand for standardized robots. In many automation projects, they help to achieve a combination of high performance and high cost-efficiency. With the new pic A pneumatic sprue picker, the market now has a flexible, compact solution for separating sprues, and easy removal of small injection-molded parts.

Sesotec GmbH, Schönberg, Germany, extends its range of free-fall metal separators with the Rapid Pro-Sense 6. This system is optimized for applications in the plastics industry, especially for granulate and compound producers. Used for quality assurance it, among other things, also is suitable for applications involving abrasive material. The model features a high detection accuracy and thus provides protection against complaints caused by metal particles, and the logbook function allows full traceability. Constant high product quality is thus guaranteed.

At the Hannover Messe in Hanover, Germany, which has just been postponed, B&R Industrial Automation GmbH, Eggelsberg, Austria, will be one of the first to present an automation portfolio that speaks OPC UA over TSN. And with that, the vision of interface free communication from the sensor to the cloud is now a reality. The open standard means OEMs are no longer locked in to a specific vendor and enjoy greater freedom in the design of their machines.
