In this e-Learning module, shrinkage and the different types of shrink-related defects will be identified. This module will also identify the causes of these shrink-related defects. In addition, shrink defects will be distinguished from gas defects and shrink control measures will be described. The module will briefly examine some gating system topics and how shrinkage can be affected by the gating system. By the end of this module, you will be able to identify the types of shrink-related defects and list two control measures to preventing shrink defects. (0.1 CEU)
