Designing Plastic Parts for the Injection Molding Process

Get a fundamental overview of plastic part design for the process of injection molding – ideal for engineers and designers who are accustomed to working with metals, but faced with metal to plastic concerns. Examine plastic materials, behavior and selection, engineering design, manufacturing considerations and assembly methods.

This course can be applied to the Plastics Technology Certificate.

Who Should Attend

Engineers and designers who are accustomed to working with metals and are faced with metal to plastic concerns.
