Study Notes
Casting Process
- Involves melting a material, heating it to proper temperature, and pouring it into a mold to solidify in a desired shape
- Molten metal flows by gravity or other force into a mold, solidifying in the shape of the mold cavity
- One of the oldest shaping processes, dating back 6000 years
- Variety of casting processes use different pouring methods: gravity, vacuum, low pressure, or high pressure
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
Disadvantages of Casting
- Different disadvantages for different casting processes
- Limitations on mechanical properties
- Poor dimensional accuracy and surface finish for some processes
