  • Course: Scientific Injection Molding II
  • Course #: PLST2245
  • Total Credits: 4

Course Description

This course is a continuation of Scientific Injection Molding I and is designed to introduce the student to Scientific/Decoupled molding methodologies and techniques, which are critical in medical and other plastics manufacturing. Students will learn Scientific/Decoupled II molding from the "Plastics Point of View", which includes building and documenting a Scientific/Decoupled II process. The course also includes plastics behavior and the molding machine controls, instrumentation devices used in molding, process documentation worksheets with studies and tests. Students will also apply their learning on interpreting machine and cavity pressure curves, and computerized data acquisition devices. This course utilizes Paulson Training Programs, inc. interactive web-based training.
