| Abstract Scope |
Cold-walled, horizontal injection molding has proven to be a commercially viable process for producing high-quality net-shaped parts from bulk metallic glasses (BMGs). The current talk focuses on the initial development and testing of a lab-scale version of a pneumatically-driven, cold-walled injection-molder designed in 2007 and built in 2012 at NASA JPL/Caltech. The equipment was used to study the manufacturing of BMGs and BMG metal matrix composites under a variety of molding conditions. Infrared imaging was calibrated with embedded thermocouples to produce non-contact temperature measurements and processing profiles were developed under different induction coil designs. Lessons-learned in the development of BMG injection molding continue to have implications on current manufacturing methods. |
