Announcement of the 12th CONNECT!

This year, MF SOFTWARE is once again organizing the CONNECT! European Moldflow User Meeting. This will be the 12th anniversary of the event and, due to the Corona pandemic, it will be held online for the second time in a row.

Even if we have to do without the big CONNECT! in Frankfurt again, we are working on putting together an event that is all the more interesting and filled with top-class presentations. So stay tuned and of course Save the Date!

Addendum to the 11th CONNECT!

The 11th CONNECT! European Moldflow User Meeting and the first online event of this kind was a great success.

We would like to thank all participants and speakers for their participation, feedback and time together during this event, which was more unconventional due to the Corona pandemic. We hope to host the event in Frankfurt again next year and look forward to exciting presentations and a large number of participants.

Understanding the Effects  of Gravity and Inertia on Heavily Filled Polymers

This talk will discuss the effect of gravity and inertia on the filling behavior of heavily filled polymer systems compared to conventional thermoplastics where these effects are typically ignored. The advanced options to include gravity and inertia have long been available in Autodesk Moldflow Insight, however, it can be unclear when to incorporate these effects and how the results will be impacted. The impact can range from jetting into the cavity to flow patterns showing preferential flow through the cavity. While these effects have been traditional included in very thick thermoplastic parts, heavily filled systems can show these effects at conventional injection molding thicknesses. To start understanding what the extent of these effects could be; we will analyze the flow patterns of thermoplastics and heavily filled systems at different orientations with respect to gravity, thicknesses, and filling velocities.

Implementation of a 3D crystallization model using the Solver API feature

The ability to model accurately the crystallinity content evolution of a semi-crystalline material during a transformation process has been under investigation in the last couple of decades. The main motivation lies on the strong correlation between flow-induced crystallinity and material parameters such as viscosity and specific volume. Therefore, knowing how the crystallinity evolves during processing is crucial to estimate correctly the final properties of a produced part and additionally to enable a simulation-driven control of the production process. The ultimate objective of the work is to implement a user-defined flow-induced crystallization model in 3D in Autodesk® Moldflow® Insight. Hence, as a first step, we implemented and tested numerically a quiescent model using the Solver API feature. This presentation will focus on demonstrating the use of the Solver API tool for defining a 3D crystallization model in Autodesk® Moldflow® Insight Scandium 2019 while using the quiescent implementation as example.

SynAPI solutions by MF SOFTWARE

The presentation shows current topics from the area of API programming at MF SOFTWARE. Starting with the new tool for tolerance analysis during the development process, a software will be presented which allows to analyze different dimensions with their corresponding tolerances from CAD programs in Moldflow and to monitor them in the further development process.
The MFS Report Generator will be presented secondly, which allows the creation of user-defined reports. By batch processing of projects, this otherwise time-consuming activity can be shifted into the night and thus binds practically no more resources.
Finally, the new “Gate and Go” and the toolbox are discussed. “Gate and Go” is an application for designers that offers specific support with the use of red /green indicators and design instructions during the design process only by specifying an injection point (Gate) and starting the simulation (Go). The toolbox supports the administration of own macros and is the toolbox in which all available Autodesk macros and other MFS Mini-API solutions are collected.

ENGEL sim link – The Connection of Two Worlds: Simulation and Production

To this day, many findings from the simulation of injection moulding processes on the machine remain unused. ENGEL sim link makes it possible to transfer data from the simulation to the injection moulding machine and vice versa. This provides the machine operator with an initial proposal for mould sampling from the simulation, making use of the simulation engineer’s expertise and knowledge of the limits of the injection moulding machine used. In addition, ENGEL sim link can also be used to transfer data from production to Autodesk Moldflow to accelerate troubleshooting and increase process understanding. The simulation engineer thus has the opportunity to close the loop between simulation and production and create a digital twin.

Moldflow vs. Moldfloor – The Pressure to Do it Right

Moldflow simulation is used to support material selection, as a tool for the design of tools and components and as a processing guide. With regard to processing, an analyst can be asked to determine ideal process conditions in order to meet various requirements for part quality with the widest possible process window. Similarly, the analyst can be asked to correct errors / optimize an existing process. Some companies and OEMs evaluate an analyst on how well the simulation results and moldfloor match. However, sources of error between Moldflow and moldfloor must be considered. There are many process parameters that, if not correctly captured and/or reported or not well understood between the analyst and the moldfloor, have a very low chance of a good correlation between the Moldflow results and the moldfloor data. This presentation will highlight some of the sources of error, focusing on a few key points to consider when using simulation for process development and troubleshooting.

Optimization of Hot Runner Systems for Large Plastic Components

Plastic injection moulding is the most common production process for the cost-effective and time-efficient manufacture of high-quality plastic parts. To reduce waste in the upcoming production, hot runner systems and nozzles at the injection points are preferred to cold runner systems. Since the injection process also has a significant influence on the filling pattern, the fibre orientation and thus on essential structural component properties, a further objective in development is the design and optimisation of a suitable gating system.
However, complex part geometries usually require very sophisticated demoulding strategies. Consequently, there are only a few options available for the installation of hot runner systems. Many possible positions do not offer sufficient space for the nozzle and cooling. It is therefore worth spending time and effort to find the best balance between the gating and demolding system. On the one hand, this provides a high-precision mould and a production process for the best part quality, and on the other hand, a lot of time and money can be saved in production.
This presentation gives a short insight into the MAHLE pre-series (development) process to find and optimize an injection and removal system for a tool. The results of both the rejected and the final variant are shown to give an overview of the development steps that have been carried out.
