Injection molding is a complex manufacturing process involving temperature and pressure. During the molding process polymer materials experience complex molecular chain deformation while undergoing temperature and pressure changes. Molded part properties and performance are dependent on and influenced by design complexity and the molding process. In this lesson you will learn about molded-in stress, specifically flow-induced residual stress, and why it is an important aspect of molding high quality parts.
This lesson covers: the significance of flow-induced molded-in stress in the injection molding process, how polymer material affects flow-induced molded-in stress, and how processing conditions impact flow-induced molded-in stress.
