Centrifugal casting (or “rotocasting”) constitutes a highly specialized form of casting.Fabricators rely upon centrifugal forces to disperse molten metal evenly through the mold. This results in the generation of finely grained, densely compacted metal workpieces.

What Is Centrifugal Casting – Centrifugal Casting Define
Centrifugal Casting is a technique and method of injecting liquid metal into a high-speed rotating mold, so that the liquid metal is centrifugal motion to fill the mold and form a casting. Due to the centrifugal movement, the liquid metal can fill the mold well in the radial direction and form the free surface of the casting; the cylindrical inner hole can be obtained without the core; it is helpful to eliminate the gas and inclusions in the liquid metal; it affects the metal The crystallization process improves the mechanical and physical properties of the casting.
According to the spatial position of the rotation axis of the mold, common centrifugal casting can be divided into horizontal centrifugal casting and vertical centrifugal casting. Centrifugal casting when the rotation axis of the mold is in a horizontal state or when the angle with the horizontal line is small (4°) is called horizontal centrifugal casting. Centrifugal casting when the rotation axis of the mold is in a vertical state is called vertical centrifugal casting. Centrifugal casting in which the rotation axis of the mold has a large angle with the horizontal and vertical lines is called inclined axis centrifugal casting, but it is rarely used.
Centrifugal forces help spread the molten material evenly. The metal cools as the mold continues to spin. Manufacturers may choose to maintain a constant high temperature for a specified period of time through the selective use of coolants. After the molten metal solidifies and cools, the manufacturer pulls the workpiece from the mold, e.g. with the assistance of a pipe puller. Today many high volume production environments completely automate the centrifugal casting process.

The Application Field Of Centrifugal Casting
Centrifugal casting was first used to produce cast pipes, and then this process has been rapidly developed. At home and abroad, the centrifugal casting process is used in metallurgy, mining, transportation, irrigation and drainage machinery, aviation, national defense, automobile and other industries to produce steel, iron and non-ferrous carbon alloy castings. Among them, the production of castings such as centrifugal cast iron pipes, internal combustion engine cylinder liners and shaft sleeves is the most common. For some forming tools and gear castings, centrifugal force pouring can also be used for the molten mold shell, which can not only improve the accuracy of the casting, but also improve the mechanical properties of the casting.
