2015 - Welcome to the Moldflow Experience - Update

23. and 24. June 2015

6. CONNECT! European Moldflow® User Meeting

in Frankfurt/Main organized by MF SOFTWARE

Welcome to the Moldflow Experience

 

Only 5 weeks left until 6th CONNECT! European Moldflow User Meeting.

In addition to talks, which will be translated from English to German and vice versa by simultaneous translators, you can count on training sessions about MuCell or other software related and linked to Moldflow like e.g. Digimat.
The evening event on June 23, as well as the “Hot Runner” race at morning on June 24 offer the chance for conversations in a relaxed environment.

Your opinion counts!

Again, Caroline Dorin (Principal User Experience Designer, Design, Lifecycle and Simulation Product Group) offers individual appointments to discuss several topics. Some of last year’s users’ improvement wishes have already been implemented in the new Moldflow release.
This year Caroline asks for your feedback concerning different Moldflow features, amongst other things:

  1. requirements for a more comprehensive, multi-shot (>2K), multi-process overmolding simulation.
  2. issues in relation to warpage visualisation and the correct use of anchor planes
  3. further requirements for the “Pathlines” result
  4. some new geometry editing tools for Parametric Optimization and on some new workflows for material selection
  5. some incremental additions that have been made to the existing overmolding capabilities.

In case you are interested in an appointment, please contact Caroline Dorin caroline.dorin@autodesk.com directly. Also, Claudia Jehn jehn@moldflow.eu will happily accept your appointment inquiry.

 

Following the event, on June 25, you will have the Chance to participate in the tl_files/connect_template/bilder/news/2015/Zertifizierung.jpg
Associate Certification Exam, the first of three Autodesk Moldflow certification levels.

Moldflow applications from the perspective of an automotive manufacturer

Maik König, Audi AG

Due to the growing range of models, product variety and shorter life time of the different models, the number of required injection molding tools in addition to the development scope for plastic components is increasing. To avoid unpredictable start-up risks, caused by a high number of changes in the tool and related to that delay in deadlines, an early assurance of manufacturability already during the design phase is required. At this point begins the work of the department "Production-oriented influence on components”. That department is responsible for ensuring the manufacturability of purchased parts - from the concept phase to the start of the series tool. One important way for covering this are injection molding simulations. In practice we see that the quality and the way of handling the simulation results provided by partners is often very different. Excerpts which applications are needed by OEMS are part of the presentation.

 

 

Simulation of transfer molding process for power modules

Armin Kech, Robert Bosch GmbH

Within this work a comparison is shown between the single steps of the trans-fer molding process used for electronic packaging of power modules and the simulation in MOLDFLOW. The single steps are: - Preheat time of the pellets in the pot
- Transfer phase of plasticized pellets through the runner in the cavities
- Curing phase in the mold
- Post-Mold-Cure in an oven with nitrogen gas
Questions are addressed like the influence of active and non-active vacuum, wire-sweep or the formation of air traps during filling and curing phase. This work shows how MOLDFLOW is placed today and where there are gaps for a complete description of the process.

 

 

New scopes for component design through MuCell® process simulation with Moldflow

Harald Heitkamp, Trexel GmbH

The MuCell® microcellular foam technology in injection molding of thermoplastics offers unique flexibility in terms of design and cost saving opportunities that do not exist in conventional injection molding. The MuCell® method makes it possible to produce the plastic part with a wall thickness that meets the functionality of the components and does not have to submit to the design requirements of the conventional injection molding process. The combination of reducing the material density and the design of functionality often results in weight savings of about 20%. However, in order to consider this idea directly at the component design and efficiently use it, it is increasingly important to simulate the filling behavior of gas-laden melt in the cavity and to obtain information on cell distribution and density reduction of the overall contour, which in turn allows conclusions on the mechanical behavior of the designed components.

Moldflow ASMI 2016 offer this calculation option.

 

 

Autodesk Moldflow at the University of Bradford – short and long fibre reinforcement material injection moulding analyses

 

tl_files/connect_template/bilder/Referenten/2015/f_caton-rose_w142.jpg

Philip Caton-Rose, University of Bradford

Collaborations between University of Bradford and Autodesk Moldflow span over 15 years, with funded PhD students and research grant support investigating such effects as injection moulding process control, energy consumption, fibre orientation and more recently fibre breakage and micromoulding. Within this paper we present the latest results from our ongoing fibre orientation and fibre breakage Autodesk Simulation Moldflow Insights analyses, along with experimental investigations and validation studies. All currently available fibre orientation prediction models (Folgar-Tucker, modified Folgar-Tucker and Reduced Strain Closure) are discussed, and the relative effects of their various parameters. Some basic rules for optimum parameter selection are introduced based on simple laboratory based moulding geometries. Fibre breakage analysis is also discussed and related to fibre length measurements taken from extrudate, sprue and from within a centre gated geometry of various wall thicknesses. The importance of fibre length distributions input into Moldflow analyses will be presented as well as a view to the future in terms of collecting fibre length measurements along a typical injection moulding screw.

 

 


Induction heating simulation with Autodesk Moldflow

Dr. Stéphane Quilliet, RocTool GmbH

RocTool is the leader of induction heating variotherm systems. The main advantage of induction is the very fast heating, possible up to 400°C. Most of the applications in the automotive industry are related to elimination of any secondary operation like painting. It is now possible to simulate the induction heating with Autodesk Moldflow. We will describe the specific modeling and the heat and cool analysis. Consequently the filling and the warpage analysis are made under real heat & cool conditions. We will compare the results with previous reference FEM calculations.

 

 


We look forward to your participation!
