PLST2250 Scientific Injection Molding III

This course is a continuation of Scientific Injection Molding II and is designed to introduce the student to Scientific/Decoupled III molding strategies and techniques, which are critical methods, techniques, and strategies in medical devices and other plastics manufacturing. The content includes practical application of cavity pressure control, instrumentation, and data acquisition to accomplish Scientific/Decoupled III molding and process control. Students will also apply their learning and skills on understanding Scientific/Decoupled III molding practices to produce process repeatability by machine and mold monitoring techniques to achieve the process control solutions.




PLST2245 and Injection Molding certificate or equivalent experience with instructor approval
