Autodesk® Simulation Moldflow® Insight is a powerful tool to simulate the different stages of the injection molding process. New capabilities of this tool include a transient mold thermal analysis. This type of simulation combines the mold filling and packing simulation with a heat transfer analysis, hence providing increased accuracy in the mold thermal solution. Attendees see the variables that influence the analysis results and improvements that can be done to the model to more closely correlate with the real life. For this purpose, simulation results are compared to experimental results over a design of experiments varying coolant temperature, injection rate, barrel temperature, and cooling time. The experimental results, obtained using an instrumented mold, include temperature and pressure data. Finally, the differences between the transient cooling analysis and the conventional cycle average solution are compared as well as their correlation to experimental results.
- List the variables that may affect the accuracy of the simulation results
- Identify improvements that can be performed to a model in order to increase its accuracy
- Describe the benefits of the transient cooling analysis
- Distinguish the differences between cycle average thermal solution and transient cooling solution
Professor Stephen Johnston has his BS in plastics engineering technology from Penn State Erie, The Behrend College, and his MS and PhD in plastics engineering from University of Massachusetts Lowell where he is now an associate professor in the Plastics Engineering department. He teaches graduate and undergraduate courses in the areas of plastics product design and mold design, which heavily utilize Moldflow simulations. Johnston's research interests include part design and mold design utilizing computer-aided engineering and manufacturing technology. He also works in the areas of process monitoring, process control, and process development for injection molding. His research group is funded by industry to investigate aspects of the injection molding process. As a result, he is inventor on 3 patents and author of over 30 reviewed publications.
