Casting in Manufacturing:

Definition:

Casting in manufacturing refers to the process of shaping materials by pouring molten metal, plastic, or other substances into a mold, where it solidifies to form a desired shape. This method is widely used in various industries to produce complex parts and components with high accuracy and repeatability.

Sub-Categories of Casting in Manufacturing:

  1. Die Casting: Utilizes metal molds (dies) to produce metal parts with high precision and surface finish.
  2. Sand Casting: Involves creating molds using sand and a binder to cast metal parts.
  3. Centrifugal Casting: Rotates a mold at high speeds to distribute molten material evenly and create cylindrical shapes.
  4. Investment Casting: Uses wax patterns and ceramic molds to produce intricate metal parts with fine detail.
  5. Plaster Casting: Utilizes plaster or gypsum molds to cast objects with smooth surfaces and intricate details.
  6. Molding: Process of creating molds or patterns for casting operations.
  7. Lost Foam Casting: Produces parts by evaporating polystyrene foam patterns in a mold filled with molten metal.
  8. Vacuum Casting: Uses vacuum pressure to draw molten material into a mold cavity for casting.
  9. Casting Process: Overall process of casting operations, including mold preparation, pouring, solidification, and finishing.
  10. Patternmaking: Creation of patterns or models used to produce molds for casting.
  11. Cope and Drag: Two-part mold used in sand casting to create hollow objects.
  12. Expendable Mold: Mold that is destroyed or consumed during the casting process.
  13. Loam Sand: Specialized sand mixture used for molding large and irregularly shaped castings.
  14. Pouring: Process of transferring molten material into a mold cavity during casting.
  15. Steel: Casting process specific to steel materials, including carbon steel, stainless steel, and alloy steel.
  16. Continuous Casting: Method of casting where molten metal is continuously poured into a mold to produce long, continuous shapes.
  17. Pressure Casting: Applies pressure to force molten material into a mold cavity for high-density and high-quality parts.
  18. Slush Casting: Partially fills a mold cavity with molten material, allowing excess material to drain out, resulting in hollow parts.
  19. Aluminum: Casting process specific to aluminum materials, known for its lightweight and corrosion-resistant properties.
  20. Finishing: Post-casting processes such as trimming, machining, and surface treatment to refine and prepare cast parts for use.
  21. Iron: Casting process specific to iron materials, including gray iron, ductile iron, and malleable iron.
  22. Other Casting Manufacturing Disciplines: Additional casting methods and techniques used in manufacturing.
