10. CONNECT! European Moldflow User Meeting 2019
Save the date - On June, 4th and 5th 2019 MF SOFTWARE celebrates the 10th anniversary of CONNECT! in Frankfurt Main.
Lectures about new and existing functions in the Moldflow software, exchange of experiences among the Moldflow users but also directly with Autodesk as well as workshops and information about adjacent products should help you to achieve faster and greater success.
Together with you and also with new participants we would like to celebrate our 10th anniversary with a varied program.
The registration is open now. If you need a hotel room a contingent of rooms at discounted prices is available at the event hotel.
As in previous years all lectures will be translated simultaneously.

Commitment to Success
The injection molding of plastic parts is an extremely complex and is often oversimplified. Despite significant advancements over the years, our industry is still struggling to understand and manage the extreme conditions experienced by a melt as it flows through a mold and forms into a plastic part. After over 40 years since the introduction of injection molding simulation, these extreme conditions continue to handicap the development and application of this technology. If we are to be committed to success, we must continually challenge and question what we think we know. We must recognize that today’s state-of-the-art is simply tomorrows outdated practices and therefore must continually strive to do better. This presentation will present on some of the research and development conducted at Beaumont Technologies to help capture, study and manage some of the issues our industry is challenged with every day.

Multi-scale 3D-Modelling of the filling behavior of micro structured plastic optical components
During the injection molding of micro structured optical components, such as for example Fresnel lenses, the filling parameters of the process have to be tuned in a way that both the microstructures and the full part scale meet the geometrical specifications to achieve the desired functionality. Process aspects such as formation of weld lines, cavity balance, hesitation and full replication of the micro features can be predicted using simulation. To do so, governing equations, boundary conditions and model geometry have to be developed and validated for the multi-scale nature typical of micro structured components. In this research, 3D modelling of the filling behavior of a micro structured Fresnel lens was performed using the Moldflow® software. Meshing using selected domain regions together with localized selection of HTC (Heat Transfer Coefficient) was critical for the experimental validation of the models both at the micro and the macro dimensional scale, which was performed using an integrated approach including the injection molding short shots method, optical coordinate metrology and laser confocal microscopy.

Validation of the Moldflow prediction of sink marks and voids using series products and test components
In technical plastic components, voids and sink marks are frequently occurring failure characteristics which range from optical failure to component failure. In order to avoid voids and sink marks in the development phase and to show customers possible effects, exact prediction methods are necessary. Moldflow Insight offers various possibilities for this, e.g. the analysis of volume shrinkage. Since volume shrinkage values do not allow a direct statement on the depth of the sink marks and/or the size and number of the voids extensive tests for validation have been carried out. The main focus was on glass fibre reinforced PA and PBT. The results and their interpretation will be presented in extracts during the lecture.
We are looking forward to your participation.
