Metal Casting: Processes, Gating, and Riser Design

The core idea of the document is: Metal Casting in Manufacturing. ​It outlines casting as a manufacturing process that uses physical and chemical methods to alter materials into valuable products. The notes focus on the Sand Casting method, detailing its basic components like the Cope, Drag, Pattern, Core, and Gating System. ​A major theme is the design of the Gating System and Risers to ensure a defect-free casting. Key design principles discussed include using Bernoulli's theorem for flow analysis and applying Chvorinov's Rule (and related methods like Modulus and Shape Factor) to control the directional solidification and prevent shrinkage defects. The notes conclude with a summary of common casting defects and inspection methods.
