9. CONNECT! European Moldflow® User Meeting

 

5th - 6th June 2018, Frankfurt/Main

 

Only a few weeks to CONNECT! 2018

 

There are many good reasons for your participation in CONNECT! 2018. Besides two full days of lectures on Moldflow, hands-on labs and an exhibition on related topics, CONNECT! offers a valuable opportunity to get to know other Moldflow experts and highly responsible Autodesk Moldflow staff members.

We cordially invite you to participate in CONNECT! 2018 as well!

 

Specific Topics

CADdoctor

 

tl_files/connect_template/bilder/news/2018/caddoctor_kl.jpgThe distribution of CADdoctors by Autodesk was discontinued. Up to 30 days after expiration of your individual maintenance, however, you still have the opportunity to continue using the product at unchanged conditions.

For all questions about CADdoctor, MF SOFTWARE and its sales partner CAMTEX will be at your disposal during the event.

 

 

 

Moldflow User Experience Team

This year MOE ZUN from the Moldflow User Experience Team is available for individual appointments to discuss your experiences with Moldflow and to present new functions in the early development stage. The following topics will be of particular interest in 2018:

 

  1. New concepts about a generative design tool that would help you design cooling channels for injection molds.
  2. Mold fatigue - in which typical scenarios do you commonly experience this problem and how is it currently solved?
  3. "First Time Right" Molding - a new workflow should make it possible to define upfront dimensional requirements which will drive changes to the part geometry. This uses local windage corrections.
  4. New ways to provide material data to Autodesk, consume and search for material data in Moldflow.

 

Appointments can be made directly with Moe Zun via the following website:

Metallic Effect Pigments - Development of a Method to Predict Optical Defects

Metallic effect pigments are added to thermoplastic materials to achieve a metal-like optical appearance at the component surface. The application of such materials in automotive exterior components manufactured by injection molding offers a great cost potential, due to the elimination of expensive painting processes. The pigment orientation as a result of the manufacturing process can lead to optical defects at the component surface, especially in case of inhomogeneous pigment orientations. The challenge in component and tool design is therefore the assurance of a production-oriented design in the early phase of the vehicle development process. AUDI AG is working together with PEG GmbH on the development of a methodology to predict optical defects. In this presentation, the fundamental problem will be presented on the basis of experimental investigations and the procedure for simulative analysis of optical defects will be explained. The method is applied to different components and the currently achievable prediction accuracy and possible development potentials are discussed.

Microstructure Prediction of Weld Lines in Short Fiber-reinforced Injection-molded Thermoplastics

The mechanical design of short-fiber reinforced thermoplastics requires taking into account the particular mechanical properties of the weld lines, which depending on the material, the processing conditions and the end-use mechanical solicitation can become critical spots of the injection-molded part.

Today, a common mechanical simulation approach for short-fiber injection-molded thermoplastic parts is the main-field analytical homogenization. In this modelling approach, the mechanical properties of the constitutive phases and the fiber microstructural information (aspect ratio, content and orientation) are the inputs for computing anisotropic mechanical properties at the macro-scale and solving the mechanical response of a complex part using, for example, a FE-analysis. In such context, the accuracy of the prediction of the anisotropic mechanical properties in the vicinity of the weld lines is strongly dependent on the correct description of the fiber microstructural information at the weld line zone. We present in this work an extensive characterization of the fiber orientation and fiber content in frontal and flowing weld lines produced by injection molding of short glass fiber-reinforced PBT. At the same time, we compare the measured fiber orientation in the vicinity of the weld lines with the in-Moldflow predicted fiber orientation and we discuss the current level of prediction accuracy and the open challenges in terms of prediction of fiber microstructural information at the weld lines.

Consideration of the pressure level for viscosity determination in the high-pressure capillary rheometer

Knowledge of the flow behaviour of plastic moulding compounds plays a central and leading role in plastics processing to enable the processing and the selection of suitable process settings. This applies not only to the selection of processing parameters, but also in particular to the simulative design of injection molds and processes with the highest possible accuracy at the same time. An important but currently only in a few cases considered and integrated aspect is the influence of the pressure level on the local viscosity of the plastic melt. In plastic injection moulding, high pressure differences are necessary in order to achieve sufficient flowability of the material. The resulting material-, geometry- and process-dependent compression can lead locally or globally to a strong increase in viscosity up to crystallization and solidification.

In this paper the experimental analysis method for the determination of pressure level dependent viscosity values in a high pressure capillary rheometer will be presented and illustrated with examples. In addition to the determination of the viscosity as a function of the pressure level with the aid of a counterpressure chamber, a pressure-controlled determination and the measurement of the shear rate and compression-dependent viscosity with a new type of testing device is particularly important. Among other things, the pressure levels in the test chambers and the inlet and outlet areas of the capillaries are discussed. The determined viscosity values show the high dependence of the viscosity on the pressure level which again depends strongly on the existing flow velocity. This potentially leads to solidification and thus underlines the necessity that this aspect must not be neglected in the determination of characteristic values, but especially also in the simulation.

Effect of tool bending on part deflection: a research case

Simulation tools becomes more and more popular in the last decade up to become a necessary tool for any kind of new product development. Ease of use and automated diagnostic are some keys of such diffusion lowering the required skills to understand and manage results. Anyhow successful approach to simulations cannot forget to consider the actual degree of approximation of reality. In this paper has been studied the molding process of a front lens made in polycarbonate by equipping the tool with pressure and position sensors. The test were then replicated using by different simulation model and compared to the real measurement in order to create a correlation between cavity pressure, tool bending and part deflection.

Simulation of glass fibre reinforced components in the automotive industry - A field report

The use of glass fibre reinforced plastics is standard for many components in the automotive industry. The glass fibre content significantly increases the mechanical strength of the components. However, the local mechanical properties of the component are strongly dependent on the local fiber orientation. Throughout the entire product development process, glass-fibre-reinforced components are simulated using Moldflow in order to obtain early information on quality. The fiber orientation calculated by Moldflow is also used for subsequent mechanical strength calculations. Therefore, the accuracy of the calculated fiber distribution is essential. Moldflow offers various models that can be optimally adapted using model parameters. The comparison between practice and simulation is also an important part to verify the results.
