Lectures

Prediction of voids in Moldflow and comparison with CT scans

Voids can be very critical for technical applications depending on their location in the part. Therefore an accurate prediction is needed. During the injection moulding process, an efficient holding pressure phase is required to decrease the risk for voids. If a new product is developed, the influence of part's geometry, feeding system and process settings can be simulated. This presentation will focus on Moldflow® software capabilities to predict the voids positions and sizes. The correlation with X-ray CT measurements will be shown. Furthermore, an investigation on scanning resolution will illustrate more details about the structure of voids and the influence on their detection with the defect analysis module from VGStudio MAX® software.

 

Dr. Sylvain Rivière

Dr. Sylvain Rivière, EMS Chemie AG (CH)

After graduating in mechanical engineering from the University of Strasbourg in 2008, Sylvain Rivière worked during one year on the screening of new polymer composites for the DuPont Company. Then he wrote a Ph.D. thesis entitled: «Optimization and simulation of reactive rotational moulding» at Arts et Métiers ParisTech, a French engineering school. Since 2013, he works within the CAE service of EMS-GRIVORY where he is in charge of structural analysis, Moldflow simulation and CT analysis for customer projects.

 

 

Simulative analysis of car interiors - identification of economic and technical potentials

The department "Production-oriented interference of components” is responsible for ensuring the manufacturability of parts which they are predominantly injection-molded plastic parts. Manufacturability includes the plastic-oriented component design but also a robust and reasonable tool design.

Within a project a large number of interior components were checked with Moldflow simulations. The main target was to evaluate the quality of the design and tool concepts.

The results were evaluated for component design and injection molding process. From this technical and economic potential aroused which will be used in future projects.

Maik König studied plastics engineering at the University of Applied Sciences in Darmstadt and graduated in 2008. After a first job within the company Röchling, he began in 2009 to work as an application engineer for MF SOFTWARE and moved to Audi in 2014 where he is currently responsible for the production-oriented interference of components.

 

Parameter identification for orientation models in injection molding simulations

The lecture deals with the so-called "integrative simulation" of short fiber reinforced injection molded components and the major challenges in the simulation chain. The fiber orientation calculation in the injection molding simulation is studied more in detail. The basic model of the orientation simulation and its development and the influence of the model parameters are discussed. It is shown how fiber orientaions and length distributions in test specimens, determined by experimental μ-CT analyzes, can be used to determine the parameters of the orientation model.

Validation of flow pattern in precision micro injection moulding simulations

Just as in conventional injection molding of plastics, process simulations are an effective tool in the area of micro injection molding. They can be applied in order to optimize and assist the design of the micro plastic part, the mold, and the actual process.

Available simulation software is however actually made for macroscopic injection molding. By means of the correct implementation and careful modelling strategy though, it can also be applied to micro plastic parts, as it is shown in the present work.

Process simulations were applied to two different microfluidic devices (a microfluidic distributor and a microfluidic mixer). One of the main goals of the simulations was the investigation of the filling of the parts at both part and micro features (micro ribs and micro pillars) level. The simulations were employed for the optimization of selected gate designs for both components, the process window, the polymer flow pattern, and the part quality. The optimized designs were implemented in the tool design and mold manufacture. The simulation results were validated by cross-checking the flow front behavior of the polymer flow predicted by the simulation with the actual flow front at different time steps. These were realized by molding short shots with the realized molds and were compared to the simulations at the global, i.e. part level and at the local, i.e. feature level.

Influence of injection molding parameters on warpage, field report

The HELLA Group develops and manufactures lighting and electronic components and systems for the automotive industry. The inherent plastic components have to comply with multiple requirements (structural, decorative, functional, ...). An overall target is often to minimize warpage which can be achieved by following specific design rules. In case that these are conflicting with the function of the part or styling requirements, a more detailed investigation of the influence of injection molding parameters on warpage is required. This presentation will focus on packing profiles and their influence on the shape of warpage obtained by simulations and will conclude by a comparison with physical parts.

 

Janez Turk

Janez Turk, Hella Saturnus Slovenija d.o.o. (SVN)

Janez Turk studied physics at the Faculty of mathematics and physics at the University of Ljubljana. His primary focus during his studies was the numerical side of physics, namely numerical methods.

The topic of his degree was "Advanced numerical methods for tridimensional analysis of nematohydrodynamics". For his research into this topic he used an open source finite volume method library, called OpenFOAM, for the development of a solver to describe the flow of nematic liquid crystals coupled with orientation. After his graduation, in 2013, he started his position as a moldflow analyst at Hella, a company specializing in automotive headlamp development. He has been at the company ever since. In October 2015 he enrolled into a postgraduate program at the University of Ljubljana to study residual stresses and deformation produced during injection molding process, whilst maintaining his position at Hella.

Marko Kolenc, Hella Saturnus Slovenija d.o.o. (SVN)

Marko Kolenc studied at the Faculty of Mechanical Engineering at the University of Ljubljana. One of his main interests during his studies was numerical simulations, especially the field of computational fluid dynamics. He first started work at Hella as a student and after his graduation in 2013 he continued his position as a moldflow analyst. As part of his work he is putting a great focus on matching produced plastic parts with injection molding simulations and using this knowledge to optimize production processes.
