The Autodesk Moldflow User Experience Team will also be present to collect your requirements for new technologies. The main topics are:

 

Brand New Job Manager
tl_files/connect_template/bilder/news/2019/sjm.jpg

The Autodesk Moldflow development team has been working hard to build a create an entirely new job manager. You are welcome to test an early version of this new job manager in order to ensure it meets your needs. 

Design Adviser

If you want to be confident that your plastic part design can be successfully injection molded, while you are designing it, drop by to learn about the “Design Adviser”.

Ideal for part designers or analysts who are asked to make a part design manufacturable, this feature aims to reduce the number of design iterations your company goes through to achieve a successful design.

Test the latest unpublished generative design features that enable the creation of manufacturable designs for for a number of manufacturing processes.

Connected, Automated Simulation

The User Experience team is looking for simulation experts and/or part designers to develop a new tool for that will enable you to work together more efficiently.

If you are interested in discussing any of the above topics, please make a booking to talk to Moe Zun during the CONNECT! event here.

Flow-induced crystallization in polypropylene: how processing dominates structure development

tl_files/connect_template/bilder/news/2019/Peters_Gerrit_w110.jpg

Depending on the conditions, Isotactic Polypropylene (iPP) can form different crystalline phases and different crystalline morphologies, as it can be clearly seen in injection moulding samples by applying X-ray scattering methods. Over the sample thickness, a distribution of four different crystal phases (α, β, γ, meso) and multiple crystalline morphologies (spherulites and shish-kebabs) is found that depends on the local thermo-mechanical history.

A prototype industrial flow device (piston driven slit flow) combined with in situ wide angle X-ray diffraction and small angle X-ray scattering was used to measure the evolution of these (oriented) crystalline structures and phases for different flow conditions. On the basis of the experimental results, an accurate model was developed, able to describe flow-induced crystallization of isotactic polypropylene at high pressures and shear rates.

In the present work, the model is implemented in a two-dimensional finite element solver and fully coupled with nonlinear viscoelasticity, compressibility and non-isothermal flow equations. The build up and relaxation of the pressure difference and the development of the different structures and phases during and after flow are accounted for. Simulations are run for a wide range of imposed pressures and piston speeds and the model is tuned to represent the interaction between the crystallization process, the thermo-mechanical conditions and the rheological properties of the polymer.

Quantitative agreement with experiments is obtained. This experimentally validated model forms the bases for (commercial) more application directed software codes and for characterization methods.

Analysis of causes and process optimization of plastic parts with thermo-mechanical failure characteristics via Moldflow simulation

tl_files/connect_template/bilder/news/2019/Jakimenkow_Petrus_w110.jpg

The development and design of complex technical plastic components is a special challenge and in practice often leads to a compromise between economic, technical and manufacturing requirements for the component.

While the use of Moldflow simulations for molded part and mold optimization is now state of the art, the subsequent DoE simulation remains unused in many cases. This tool can be used successfully for the optimization of moulded parts and processes in order to prevent quality problems in advance.

How Moldflow can be used as a tool to analyze the causes of molded part defects and the subsequent optimization of the injection molding process is illustrated in this paper using a practical example on a valve housing made of PPSU with thermo-mechanical failure pattern.

 

Rasmus Knudsen, Novo Nordisk A/S (DK)

Standardization, automation and democratization of early phase Moldflow simulation through application programming interface

tl_files/connect_template/bilder/news/2019/Rasmus_Knudsen_w110.jpg

In Novo Nordisk developing a new injection device for drug delivery, e.g. insulin, takes a long time. Often 10,000 or more iterations are needed, each of them adding maturity, but on other side requiring time! It is estimated that the 80% of the engineering hours are spent in building, testing and verification of models – either as physical models (3D printing and soft tool moulding) or virtual models (e.g. structural and moulding simulations).

The Engineering Analysis Department delivers approximately 500 simulations pr. month. This covers structural, moulding and tolerance simulations/calculations. We have a dream: Being able, within a few years, to run a complete virtual test program of a device overnight with a single mouse click.

To fulfil our dream and at the same time speed up development time, we need to change the way we perform and think simulations by:

  • Making it fast and simple to do virtual testing
  • Doing more virtual testing by increasing capabilities within virtual testing

This presentation will focus on how the use the Application Programming Interface in Moldflow has reduced our average lead time on early phase simulations from 2 days down to 2 hours. It will show how design engineers with less than 5 mouse clicks are able to start an automatic Insight Moldflow simulation, and have the mouldability of their part evaluated and the results presented in a simple and easy-to-understand dashboard format.

Vereinfachte Kopplung con Strömung und eigens definierter Faserorientierung durch Moldflows Solver API

tl_files/connect_template/bilder/news/2019/Kugler_Susanne_w110.jpg

Short fiber-reinforced thermoplastics are a promising substitute for metal parts, since they are easy to process and show high mechanical strength. Accurate simulative prediction of failure and lifetime of such polymer parts can reduce development costs significantly.

This can be achieved by implementing more precise material models to describe the various properties. Additionally, the rheological properties of fiber-reinforced parts are anisotropic and dependent on the fiber orientation. Therefore, a coupling between flow and orientation increases the prediction accuracy.

In this presentation, we focus on the implementation of a state-of-the-art fiber orientation model and a simplified coupling to the flow using Moldflow’s Solver API feature. The main motivation behind this work is to obtain a better prediction of the fiber orientation in a simple plate in comparison to measured results.

 

 

We are looking forward to your participation.
