Centrifugalstøbning

Centrifugalstøbning is a casting process that utilizes centrifugal force to distribute molten metal into a rotating mold. The mold is typically a hollow cylinder, which spins rapidly around its longitudinal axis. Molten metal is poured into the spinning mold, and the centrifugal force presses the metal outwards against the mold's inner surface. This action ensures that the metal fills the mold completely and forms a dense, uniform casting. As the metal solidifies, the centrifugal force continues to play a role in creating a sound structure with fewer defects.

The process is particularly well-suited for producing hollow cylindrical parts such as pipes, tubes, bushings, and liners. The internal and external surfaces of the castings are often formed by the mold itself, resulting in good dimensional accuracy and surface finish, which can reduce the need for subsequent machining. Different types of metals can be used in centrifugal casting, including ferrous and non-ferrous alloys. The speed of rotation and the pouring temperature are critical parameters that need to be controlled to achieve optimal results. This method is known for its efficiency in producing large quantities of these specific shapes.
