In cars, LEDs are taking over ever more applications and are increasingly used as differentiating design elements. In order to ensure a high luminous efficiency even with complex geometries and elongated structures, Engel has developed a new plasticizing process for manufacturing light guides.

The transformation of the automobile also strongly affects the vehicle interior. Light is gaining in importance as a design element

Less Granules  Stock Means More Quality

The required screw diameter can be ascertained on the basis of the shot volume. The formula for the average residence time can be used to estimate the degree of utilization and the thermal load on the material.

Various shapes of plasticizing screws. The correct design is approached in several steps

Part 1 of the Series Discusses the Basic Design of a Plasticizing Unit and the Correct Choice of Injection Unit

All about Plasticizing Screws

To be able to carry out the practical test in a resource-saving manner, the designers use simulation tools to assess the screw geometry. What is important here is explained using a 3-zone screw as an example.

The screw geometry is finely optimized in several calculation steps until the desired result is achieved. Subsequently, test screws are manufactured in original size and tested in practical tests with various material types

Part 2 of the Series Deals with Basic Methods for Evaluating a Screw Geometry

Lightweight parts, energy-saving processing or the practice of combining several process steps into one can all be subsumed under one current buzzword: sustainability. A technology that is highly promising in this regard is thermoplastic foam injection molding.

In physical foam injection molding, a blowing gas is injected into the polymer melt during plasticizing

A Special Process that Is Becoming a Sustainable Normal Case

In the second part of the series, calculations were carried out on the throughput behaviour, pressure build-up capacity and the melting process on the basis of an exemplary geometry. These results are now to be examined in more detail and subsequently optimized.

Through empirical tests and simulation-supported test series, a screw can be designed in a tailor-made manner for the respective application

Over past months, many in-house workflows and development processes have slowed down and also changed. Nevertheless, time has not stood still, also not in injection molding technology. The debate and development have been shaped by two themes: digitalization and the circular economy. Below are some examples of developments and projects that underpin this trend.

A Question of Class

On the test stand: the University of Paderborn, Germany, investigated conventional and new concepts for extrusion screws in order to achieve higher throughputs while retaining machine sizes. The energy-transfer screws, a further development of the wave screw, scored particularly well.

On the Wave to Successful Mixing

Skilful application of the evaluation and analytical options afforded by process simulation, including designing the best temperature-control system and making comparisons with alternative manufacturing processes, smoothes the way to efficient product development and manufacturing. Doing this from the very start of a project enables investments to be weighed and qualified, and technical, economic or environmental concerns to be taken into account, as exemplified here by a part with a high-gloss surface.

Engel’s new “Parameter Limits” feature provides a remedy. It supports injection molders in keeping the parameters constant within a process window.

With the new Parameter Limits feature, tolerance ranges for up to 150 process parameters can be fixed directly in the machine control system for up to 150 process parameters. A change of the selected setpoint values is then only possible within the defined process window.

Keeping Setting Parameters  under Control

In production and research, process data and previously defined quality values are tracked to determine optimization models and pursue consistent quality management. In contrast, data that is not relevant to the specific application is rarely recorded.

Structure and interconnection along the information-pyramid subsequently generate knowledge from sensorsignals.

The iQ product family from Engel will gain a new member at K 2022. iQ hold control automatically determines the optimum holding pressure time for the particular mold with no input from the operator.

 The optimum holding pressure time is often lower than that established at the beginning. In these cases, the cycle time is shortened.

Products made from bio-based plastics must undergo the same testing procedures as conventional plastic products to access the market of the European Union (EU). Thereby a health risk for consumers is excluded. Biodegradable or compostable plastics must undergo additional tests.

Biodegradable plastics certified for industrial composting have to meet a fixed limit for heavy metals and other toxic and hazardous substances
