Smart assistance systems are paving the way for self-optimizing production. Automatic correction of quality-relevant parameters is already reality for individual phases of the injection molding process. At K 2019, Engel presented the iQ weight control with the example of a recyclate application for the first time.

The ComoNeoPredict process monitoring system is a proven option for ensuring the required quality in the injection molding production of medical devices.

In the medical technology industry, a high and validated product quality is inevitable.

When Validated Quality Is Not a Competitive Advantage

A tool logbook on paper is often not to hand just when you need it most. Or it is incomplete, since it is time consuming to keep the information up to date. A cloud-independent, electronic tool log, which is directly integrated into the tool could make all the relevant data available directly.

Data Management at the Tool

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.

Part 2 of the series on the Plastics Innovation Center 4.0 (PIC 4.0) at RWTH Aachen describes the procedure by which industrial use cases of a Smart Factory are identified and converted into real testbeds within the PIC 4.0.

Use Cases of Digitized Plastics Processing

Maintaining competitiveness while producing in Germany requires not only cost-efficient production, but also high-quality products. Vorwerk Elektrowerke is accepting this challenge. In collaboration with the Institute of Product Engineering at the University of Duisburg-Essen, Germany, the company is testing a 100 % inline quality monitoring system as well as a quality prediction using machine learning.

Customers who choose the Kobold VK 200 vacuum cleaner expect top quality. To ensure this, efforts for the introduction of Industry 4.0 measures are taken in the production plant in Wuppertal, Germany

Inline Quality Monitoring and  Data-Based Quality Prediction

Because it has not yet been possible to exploit the full potential of digitization in plastics processing, the Institute for Plastics Processing at RWTH Aachen University is building a new application-oriented research infrastructure along the lines of a Smart Factory. Kunststoffe is accompanying the building of the Plastics Innovation Center 4.0 with a series of publications. Part 1 describes the concept and the initial demands on the physical infrastructure.

Moving with the Times

A consistent flow of data and information is essential for digital solutions and meaningful analytics. The introduction of potential solutions is therefore often associated with high costs for data preparation.

M-Hub was launched at the K-show 2019. One year after, the app has reached more than 8000 professionals and 1500 companies from more than 80 countries.

The Plastic Industry in Your Hand

After the focus was on individual manufacturing and model-supported process set-up in recent years, the Institute for Plastics Processing (IKV) at RWTH Aachen University is linking the two aspects of digitalization and circular economy at K 2022.

After the focus was on individual manufacturing and model-supported process set-up in recent years, the Institute for Plastics Processing (IKV) at RWTH Aachen University is linking the two aspects of digitalization and circular economy at K 2022. The aim is to make the processing of post-consumer recyclates (PCR) reproducible with a digital solution from the field of process control.

Exchanging the material batches (PP Systalen, Duales System Deutschland; color masterbatch: LyondellBasell) changes the part quality as a result of viscosity fluctuations. These changes are identified by means of process indicators and subsequently compensated via the “Injectix” automated process control concept. Injectix combines the phases, regulating the entire injection and holding pressure phase of the injection molding machine (Wittmann Battenfeld) via the cavity pressure (2x pT sensors: Kistler) as controlled variable. This achieves a more robust process control, since no changeover processes occur in the controlled variable. Injectix continually detects process changes during part filling, so that the cavity pressure reference can be adjusted based on live data. After manufacturing, the injection-molded parts are transferred to a quality inspection cell (Kistler), which checks quality parameters such as weight, dimensional accuracy and color quality.

As a demonstrator, a stacking box (mold maker: Kroma International; standards: Hasco) is produced consisting of 100 % PCR. A laser-marked QR code (Datalogic) provides project information and process data.

The QR code on the PCR component provides project information and process data.
