Centrifugal casting is chosen when there is a need for high-quality tubular components, hollow cylindrical shapes, symmetrical parts, and a uniform grain structure, particularly in industries such as automotive, aerospace, railway, electronics, and where cost-effective mass production is required.
Centrifugal casting is a casting process that utilises centrifugal force to create high-quality, cylindrical-shaped components by pouring molten metal into a rotating mould.
The process of centrifugal casting involves pouring molten metal into a rotating mould, utilising centrifugal force to distribute the metal and create a high-quality, cylindrical-shaped component with improved density and structural integrity.
Centrifugal casting disadvantages include limited shape complexity, potential porosity, and limitations in casting size.
The benefits of centrifugal casting include uniform solidification, energy efficiency, easy impurity removal, thin wall production, cost-effectiveness for complex geometries, elimination of runners and cores, suitability for mass production, and high mechanical properties in the resulting components.
Centrifugal casting is a unique manufacturing technique that has revolutionized the way many industries produce components. This technology was discovered in the early s and has emerged as the most reliable and cost-effective method of creating high-quality parts in many applications.
Centrifugal casting is a process where molten material is poured into a rotating mold. The centrifugal force generated by the mold&#;s rotation pushes the material against the mold&#;s inner surface. The molten material, still under rotation, then cools and solidifies. This rotation exerts centrifugal force on the molten material, drawing impurities and air bubbles to the center of the part.

Types of Centrifugal Castings
There are three primary variations of centrifugal casting:
&#; True Centrifugal Casting: This method involves pouring molten material into a reusable rotating mold that is either vertically or horizontally aligned. The rotation pushes cleaner denser material to the exterior of the wall and draws impurities to the interior. These impurities can then be easily machined out creating a strong, uniform finished product. This method is ideal for making hollow tubes and rings of all shapes and sizes.
&#; Semi-centrifugal Casting: Like true centrifugal casting molten material is poured into a rotating mold. This method, however, generally uses non-permanent molds, and enough material is poured to create a solid part. This method is often used to make gear blanks and other parts where the id (or center) is not critical.
&#; Centrifuging: Also known as centrifuge casting. Molds are made with cavities branching outward from a central hub where the molten material is poured. The rotation of the mold forces the good material out to the cavities and pulls the impurities inward to the central hub. You are left with clean uniform parts in the shape of the cavities. This method is ideal for creating smaller components, such as jewelry and miniature bushings.
