Course Overview
Presents a more in-depth coverage of injection molding: process and equipment specifications, operating characteristics, thermodynamics, as well as processing variables and their effect on product quality. For the extrusion process the principles of rheology are applied to the design of extrusion dies and to understanding plastic behaviour under processing conditions. Considerable laboratory time is spent learning to efficiently set up production scale equipment and to operate it effectively. Laboratory scale studies are designed to investigate material processing characteristics and product quality as they relate to rheological properties of plastics under various process conditions.
