Centrifugal Casting and Semi-Centrifugal Casting are produced by pouring molten metal into a mold that is being rotated or revolved. Both methods can be described as castings that are spun on their own axis during the casting operation. |

|
|
| • |
The molds may be made of cast iron or steel, copper, graphite, ceramic or dry sand. |
| • |
Molten metal is poured into the spinning mold cavity. |
| • |
The axis of ration may be horizontal or inclined at any angle up to the vertical position. |
| • |
Molten metal is held against the wall the mold by centrifugal force. |
| • |
The speed of rotation and metal pouring rate vary with the alloy, size and shape being cast. |
| • |
Metal molds provide rapid chilling, resulting a sound casting. |
| • |
Castings are removed from the molds for secondary process and final finishing. |

|
|
| • |
Most metals can be cast successfully. |

|
Special characteristics of Centrifugal Casting |
|
| • |
High production rates. |
| • |
Low pattern cost. |
| • |
High integrity castings. |
| • |
Mechanical properties are nearly equal in all directions. |
| • |
The yield or ratio of casting weight to weight of metal poured is high. |
| • |
Suitable for castings that generally cylindrical and symmetric about the axis. |
| • |
Long or short runs can be accommodated |
| • |
Almost any alloy can be cast. |
