The metal injection molding (MIM) process is a combined one of the injection molding and powder metallurgy, and it is used to manufacture complex metallic parts. Now Moldflow Insight software can simulate the MIM process and predict different common defects from the MIM process, such as weld lines, air traps, and "black lines" caused by the powder segregation. The Moldflow Research and Development Team has teamed with AAC Technologies (the world's leading comprehensive microcomponent technology provider) to simulate this process. This class will introduce the basic theory, challenges, and actual cases to show the MIM feature in Moldflow Insight software. Finally, an excellent correlation was achieved with validation data provided by AAC. This session features Moldflow Insight.
- Learn how to predict the various kinds of defects of the MIM, such as weld line and "black line"
- Discover the validity of the MIM simulation by comparing with experimental data
- Discover the best practices for using the MIM feature
- Learn how Moldflow collaborates with external partners
Wayne ZhongI received my doctorate from Huazhong University of Science and Technology in the year of 2013 and has served as advanced R&D engineer in AAC Holding Inc. from then on. My research major is plastic forming simulation and advanced manufacturing technology. My topic is Research on the Simulation Method in Metal Injection Molding of stainless steel with Moldflow. In this class, the application of MIM process in consumer electronics industry was introduced briefly. The filling behavior and density distribution were intensively studied by a combination of simulation with Moldflow and forming experiments. As a result, the forming defects were predicted preliminarily.
