4-in-1 Sorter for PET Recyclers

Both the quantity of recycled plastics waste and of processed recyclates is continually increasing. However, there are still difficulties with the quality of the recycled plastics, which are impeding replacement of virgin material. In recent years, machinery manufacturers and plastics producers have introduced various further developments that improve the properties of recyclates as well as eliminate unpleasant odors and contaminants.

The latest trend in digitization  is the Artificial Intelligence of Things. It amounts to “marrying” Artificial Intelligence with the Internet of Things. In the following interview, Martin Dimmler and Martin Rugfelt discuss how companies can profit from AIoT and what plastics manufacturers can learn from its pioneers in other industries.

“Intelligent Automation Brings Systems Closer to their Optimum”

With the Metroflow gravimetric material loader from motan colortronic, plastic processors can automate important areas of the production process cost-effectively and efficiently.

Apart from injection molding and in-mold labeling (IML) additional automation steps are necessary to make the entire process for producing container packaging as efficient as possible. For this purpose, Beck Automation offers customer-specific solutions for the downstream handling of such packaging.

The aim of the project was clear: a highly automated turnkey system must replace several decentralized, operator-guided machines in order to be able to mass produce enclosures for a vacuum sensor with three inserted pins in a way that is smooth, automated and therefore faster than before in large-scale production, and error-free. The plastics processor Goerlich chose the machine manufacturer Arburg as a partner in its goal of achieving greater production efficiency.

The XPlanar motor system combines the advantages of conventional transport systems with magnetic levitation technology. This opens up completely new possibilities for handling and positioning products in the machining process. The floating effect obviates the need for mechanical guiding components and helps Plasmatreat to simplify the system configuration for plasma treatment.

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.
