Autodesk Moldflow Associate certification
On May 5, 2017, you can take part in the Associate certification managed by Jay Shoemaker, responsible for the Certification Program at Autodesk. To register for this please get in contact with Claudia.email@example.com.
The venue is the Lindner Congress Hotel in Frankfurt / Höchst. A limited number of hotel room is available for the participants at special rates, which can be called up as a self-payer until the middle of April under the keyword 'MF SOFTWARE'.
Overmolding of thermoplastic composites is a technology in which a thermoplastic composite is thermoformed and subsequently injection overmolded, as is shown in Figure 1. The near-net-shape manufacturing process is well suited for automated large series production of complex 3D structures with excellent structural performance and a high level of function integration. Although the feasibility of the process is increasingly demonstrated, it is acknowledged that there is a lack of proper design tools that can be used for a right-the-first-time design strategy. The COMPeTE project was established with the aim to create (numerical) design tools based on the basic mechanisms that underlay the overmolding of thermoplastic composites using commercially available software packages. One of the topics that is addressed within the project is the interface strength between the formed laminate and injected polymer. A test method was developed to characterize the bond strength under tensile and shear loading conditions. The characterized bond strength was used to develop and validate the numerical tools that predict the interface strength as a function of the injection molding process characteristics. The work was carried out by the TPRC and funded by industrial partners from both the aerospace and automotive industry. The TPRC acknowledges Safran, Boeing, Victrex, Johnson Controls, SMP, Harper Engineering, KraussMaffei and Autodesk for the funding of the project.
Mark Bouwman, ThermoPlastic composites Research Center (NL)
Mark Bouwman studied Mechanical Engineering at the University of Twente in Enschede, The Netherlands. He specialized in polymer science and composite materials during his master. He gained experience in this field during his internship at Daimler AG in Hamburg and his graduation project at the ThermoPlastic composites Research Center (TPRC) in Enschede. Currently, he is a researcher at the TPRC and conducts research on overmolding of thermoplastic composites. Together with industrial partners, a software tool is being developed to predict the interface strength of overmolded thermoplastic composites.
Miniaturization and function integration are common trends in industry. One consequence is that wall thicknesses of technical plastic parts get thinner and their design becomes increasingly demanding. Talking about thin walled parts with wall thickness below 1 mm, typical concerns are related to part filling, required injection pressure and flow length limits of the respective design, process, material combination. Often Moldflow simulations are used to analyze and answer some of those concerns at the earlier stages of a development project. Besides part design and processing conditions, material properties as well as the material modeling approach are challenged.
Based on a lab study comparing snake flow experiments and Moldflow simulations, this presentation examines the achieved accuracy when predicting flow performance. Different approaches for material cards including thermal dependent data, pressure dependency and extensional viscosity are studied. Real parts are studied as well and results are compared.
Dr.-Ing. Stephan Eilbracht, DuPont de Nemours GmbH (D)
Stephan Eilbracht is working as CAE specialist in the European Design Team at DuPont Germany. He is responsible for customer consulting and support in strategic development projects particularly when it comes to predictive engineering.
Before working for DuPont he graduated in mechanical engineering and polymer processing at RWTH Aachen University and the University of Wisconsin- Madison and worked for 5 years in processing R&D where he received his PhD. In 2015 he then joined the Design Team at DuPont Germany.
The presentation will focus on examples from micro-injection molding. Simulation results are compared with practical results and possibilities and limits are shown. The degree of filling (also for microstructures and 2-component parts), weld line position and pressure requirements are used as indicator variables. Particular significance is place on the setting of the heat transfer coefficients and on the PvT behavior.
Dr.-Ing. Gábor Jüttner, Kunststoff-Zentrum in Leipzig gGmbH
Gábor Jüttner studied mechanical engineering and plastic engineering at the Technical University of Chemnitz. In 1994 he became a research assistant with focus on processing-induced molding properties in injection molding, rheology and image analysis. After becoming his PhD in 1999 he took over the team management of the injection molding department at the Kunststoff-Zentrum in Leipzig as a research associate. Since 2014 he is team leader in the newly founded "MiKA - Mikro-Kunststoff-Applikation" at KUZ.
