Casting is a manufacturing process that involves pouring molten metal into a mold to produce solidified parts with complex shapes.


The liquid material, known as the molten metal, is prepared by melting the raw material in a furnace. Once the molten metal reaches the desired temperature, it is poured into the mold through a gating system, which allows the molten metal to flow into the cavity and fills it completely.

After pouring, the molten metal is allowed to cool and solidify inside the mold, taking on the shape of the cavity. This solidified metal part is known as the casting. Once the casting has cooled sufficiently, the mold is opened, and the casting is removed. Any excess material, called the gating system or sprue, is typically removed through processes such as cutting or grinding.


There are various types of casting processes, including sand casting, investment casting, die casting, and permanent mold casting, among others. Each process has its own advantages, limitations, and application areas. The choice of casting process depends on factors such as the material being cast, the complexity of the part, the required surface finish, and the production volume.


Casting is a versatile manufacturing process with a wide range of applications across various industries. Some of the common applications of casting include: Automotive, Aerospace, Defense, Energy, Agricultural , Construction and Industrial Machinery etc.

Casting can be performed with a variety of metals and alloys, depending on the specific application and desired properties. Some commonly cast metals include:

Iron: Iron casting is widely used due to its excellent casting properties and affordability.

Steel: Steel casting is employed when higher strength, toughness, and wear resistance are required compared to cast iron. Carbon steel, alloy steel, and stainless steel are commonly cast.

Aluminum: Aluminum casting is widely used in various industries due to its lightweight, good corrosion resistance, and excellent thermal conductivity.

Zinc: Zinc casting is primarily used for producing small, intricate parts with high dimensional accuracy. Zinc alloys offer good casting properties, including low melting temperature, excellent fluidity, and good surface finish.

Magnesium: Magnesium casting is employed when lightweight components with high strength-to-weight ratio are required.

Nickel-based Alloys: Nickel-based alloys, are commonly cast for applications that require high-temperature strength, corrosion resistance, and excellent mechanical properties.


Casting offers several advantages as a manufacturing process, including the ability to create complex and intricate shapes, cost-effectiveness for large-scale production, and the versatility to work with a wide range of metals and alloys. Casting allows for the production of intricate geometries that may be difficult or impossible to achieve with other methods. It is particularly suitable for large and bulky components. Additionally, casting is a cost-effective process for high-volume production, as it enables the production of multiple parts in a single mold, reducing the need for additional machining or assembly.
