Metal Casting

Metal casting is defined as the process in which molten metal is poured into a mould that contains a hollow cavity of a desired geometrical shape and allowed to cool down to form a solidified part.

Metal casting steps

  1. Patternmaking 

    • The replica of the part to be cast is made using a suitable material such as wood, metal plastic or plaster.

  2. Mould making

    • The Mould making is a multi-step process in which patterns and cores are used to create a mould. The type and how the moulds are made would vary depending on the type of metal casting.

  3. Metal melting & pouring 

    • Liquid is then melted and poured into the mould cavity either by gravity or by high pressure. Then the cast is allowed to solidify before the cast parts are removed from the mould. Again, the cast part removal will vary depending on the type of metal casting.

  4. Post processing

    • In the final step, the cast metal object is removed from the mould and then fettled. During the fettling, the object is cleaned of any moulding material, and rough edges are removed.

Jay-Bee Castings facilities also include a CNC pattern- and machine shop which allows for the manufacturing of new patterns.

Advantages of metal casting

  • Metal casting can produce complex shapes
  • Features like internal cavities or hollow sections can be easily achieved
  • Large components can be produced in one-piece cast
  • Materials that are difficult or expensive to manufacture using other manufacturing process can be cast
  • Compared to other manufacturing processes, casting is cheaper for medium to large quantities
  • Almost all the metals can be cast
  • Near net shape often without or very minor post-processing
