The basic principle of centrifugal casting involves pouring molten metal into a rotating mold. The centrifugal force generated by the spinning mold forces the molten metal against the inner surface of the mold, resulting in the formation of the desired shape. This process enables the creation of objects with a high degree of rotational symmetry and a uniform grain structure, which can offer improved mechanical properties compared to some other casting methods.

Here’s a step-by-step overview of the centrifugal casting process:

1. Mold Preparation: The mold used in centrifugal casting can be made from various materials such as metal, sand, or ceramics. It is designed to have the desired shape of the finished product.
2. Mold Rotation: The prepared mold is mounted onto a rotating axis, which can be either vertical or horizontal, depending on the specific application. The rotational speed is carefully controlled to achieve the desired casting properties.
3. Pouring: The molten metal is heated to the appropriate temperature and poured into the rotating mold. The centrifugal force distributes the molten metal uniformly along the mold’s inner surface.
4. Cooling: After the mold is filled, the molten metal cools and solidifies against the mold’s walls. The rotation of the mold helps ensure even cooling and solidification throughout the casting, reducing the risk of defects.
5. Demolding: Once the metal has solidified, the rotation stops, and the mold is opened to remove the newly formed cast part. Depending on the mold material and casting requirements, the mold may be reusable or disposable.
