What Are The Common Types Of Metal Casting Process In Engineering and Industry?

The metal casting process 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 is allowed to cool down to form solidified parts. The metal casting process can be divided into two major groups by the basic nature of the mould design. They are: 1. Expendable Mould Casting. 2. Nonexpendable/Permanent Mould Casting. 1. Expendable Mould casting: It's a method that utilizes single-use or temporary mould to produce the final casting, as the mould will be broken to get the cast product out. The expendable mould is divided into two. The permanent pattern * The evaporative pattern. The permanent pattern uses a permanent model to create the mould pattern. Examples include Sand casting, plaster mould casting, shell mould casting, and ceramic casting. The evaporative pattern uses temporary mold which will evaporate to create the mold pattern. Examples include Lost foam cast and investment casting. ▶ Sand Mould Casting: Sand is used to create the mould. ▶ Plaster Mould Casting: The moulding material is made of plaster from Paris. ▶ Shell Mould Casting: Uses resin-covered sand to form the mould. ▶ Ceramics Mould Casting: the mould is made of refractory ceramic material. ▶ Lost Foam Casting method: Uses a polystyrene foam pattern to create the sand mould, which then vaporizes when the molten metal is poured into the mould. ▶ Investment Casting: A wax pattern is coated with a refractory material to make the mould, which is then melted away before pouring molten metal into the mould. 2. Non-expendable or Permanent mould casting: uses a permanent mould that can be reused after each production cycle. Examples include; Pressure die casting, gravity die casting, centrifugal casting, and continuous casting. ▶ Pressure die casting: Molten metal is forced under pressure into a securely locked metal die cavity. ▶ Gravity die casting: The molten metal is poured inside the mould cavity using a ladle or a vessel. ▶ Centrifugal casting: makes use of centrifugal force to fill a mould with molten metal. ▶ Continuous casting: Allows metals and metal alloys to be shaped and then solidified without interruption. ★ All these are explained in the video with their advantages and disadvantages.
