Accuracy of injection molding simulation is influenced by many factors such as modeling of part geometry, mesh type and density, mathematical solution, and process settings. The focus of this class is the influence of material data on simulation precision and accuracy. This class outlines the background behind the development of Autodesk world-leading material-testing laboratories, the importance of material data to accurate simulations and, through sensitivity studies, the influence of uncertainties in material properties on simulation results.

Dr. Russell Speight is currently Senior Manager, Principal Materials Engineer at Autodesk Australia, based in the Autodesk Research and Development offices in Melbourne. He completed his Ph.D. in 1993 entitled "In-line Process Measurements for Injection Molding Control," University of Bradford, UK. Russell is an Honorary Visiting Professor of Polymer Process Measurement Technology, University of Bradford, UK, School of Engineering, Design and Technology, Advanced Materials Engineering. He is a Chartered Engineer and Fellow of the Institute of Measurement and Control, UK, with over 20 years in the plastics industry; and with over 60 research publications, he is a referee for international journals.
This class will demonstrate how the use of experimental test data of several tensile specimens of varying fiber orientation can help determine an adequate failure criteria for a given reinforced thermoplastic. This criteria can then be utilized to better predict failure of complex part designs with widely varying fiber orientations. Data for a 30% glass-reinforced PEEK material will be shown as an example of this approach to orthotropic failure analysis.
The Autodesk® Moldflow® product team and the University of Bradford have a long-standing collaboration investigating key injection molding effects such as fiber orientation, residual stresses, warpage, post-injection product performance, heat transfer, and feature replication. This class will focus on academic and industrially relevant components from the initial design phase, through production using both conventional- and micro-injection molding, to final product property assessment in terms of mechanical performance, geometric tolerances, and feature replication.
This class will show you how Autodesk Moldflow can be integrated as a new discipline in numerical optimizations of mechanical part behavior. We will show the influences of fiber orientation on mechanical behavior due to changes in design variables. We will also show how the workflow changes when Moldflow is incorporated into the optimization process. Finally, we will give examples of the use of the new method of integrative optimization.
Sabic is a major manufacturer of long fiber filled polypropylene. These long fiber filled plastics can be used to produce light weight structural components with excellent structural properties. Light weighting products is particularly important in the Automotive and Transportation industry, where weight reduction is a major driver for improving fuel economy and reduces the overall carbon footprint over the product life. To leverage the high strength-to-weight ratio, the design of the products have to account for the manufacturing process. The Autodesk Moldflow 2012 release includes the ability to calculate the orientation of long fibers during the injection molding process, which is the main component in understanding the strength characteristics of the products. The understanding of the strength of the products can then in turn be fed back into the design to optimize the design of a lightweight, yet strong, plastic product.
In this class, you will learn how to set up, run, and interpret the results for a Design of Experiment (DOE) analysis. The DOE tool in Moldflow Insight is now very powerful and can help you solve many problems. Setting up a DOE analysis to target specific requirements is the key to getting the most from the analysis. This class will introduce you to tips and tricks to get the most from the DOE analysis.
This class will discuss the requirements and workflow for simulating flow imbalances in injection molding that are caused by shear heating in branched runner systems. Validation case studies will also include the MeltFlipper design, as well as in-cavity flow imbalances that lead to race-track effects. This class will focus on the use of the Autodesk Moldflow Insight software.
Fiat is one of the top car manufacturers in the world and is using the power of simulation extensively in their product development. In this class, we will show how simulation technology can be used to validate design and quantify defects that can show up during manufacturing and final assembly. We will visualize production defects in plastic parts using Autodesk® Moldflow® and Autodesk Showcase®.
This class will discuss the tools available in Autodesk® Moldflow® Insight for simulating the dynamic temperature changes experienced in the mold during an injection molding process by using the Cool Finite Element Method (FEM) functionality. Topics covered will include modeling requirements, process setup and workflow, theory, result interpretation, and validation examples. Focus will also be given to new functionality available in the Scandium Technology Preview supporting dual-domain part models, thermoset molding and variable coolant inlet temperature processes, including Rapid Heating and Cooling of the Mold (RHCM), also known as Rapid Temperature Cycling or Variotherm. In addition, examples will be shown to demonstrate how to model complex 3D cooling channels (conformal cooling).
Do you use CAD models with Autodesk Moldflow products? If yes, then don't miss this class. We will discuss how to leverage Autodesk Inventor® Fusion technology as the front-end modeler and idealization tool for Autodesk Moldflow. We will show how to use Inventor Fusion to import CAD data, then edit and simplify it in preparation for Autodesk Moldflow simulation. We will discuss the techniques to simplify a part model and make design changes, such as modifying the part thickness and adding ribs, using Inventor Fusion. We will also discuss the alternative workflow of starting the simulation process in Autodesk Moldflow Insight, launching Inventor Fusion from Autodesk Moldflow Insight to modify geometry, and then rerunning the solver analysis in Autodesk Moldflow Insight.
