Casting Process in which molten metal flows by gravity or other force into a mold where it solidifies in the shape of the mold cavity • The term casting also applies to the part made in the process • Steps in casting seem simple: 1. Melt the metal 2. Pour it into a mold 3. Let it freeze ©2002 John Wiley & Sons, Inc. M. P. Groover, “Fundamentals of Modern Manufacturing 2/e”
Capabilities and Advantages of Casting •Can create complex part geometries •Can create both external and internal shapes •Some casting processes are net shape; others are near net shape •Can produce very large parts •Some casting methods are suited to mass production ©2002 John Wiley & Sons, Inc.
