Centrifugal casting was the invention of Alfred Krupp, who used it to manufacture cast steel tyres for railway wheels in 1852.

The conception of centrifugal force has evolved since the time of Huygens, Newton, Leibniz, and Hooke who expressed early conceptions of it.

is a casting technique that is typically used to cast thin-walled cylinders.

is a metal casting process that produces a very high quality product.

consists of producing castings by causing molten metal to solidify in rotating moulds.

The speed of the rotation and metal pouring rate vary with the alloy and size and shape being cast.

The centrifugal force is obtained by rotating the mold at a speed of 300 to 3000 rpm while the molten metal is being introduced.

The main applications for the centrifugal process are tubular or ring shaped castings.

Typical parts made by this process are pipes, boilers, pressure vessels, flywheels, and other parts that are axi-symmetric.

It is notably used to cast cylinder liners and sleeve valves for piston engines.

Also known as centrifugal rubber mold casting (CRMC).(explaination)the main features of spin casting process is the use of rubber mold and employing centrifugal force for casting. During the solidification process the mold spins on it central axis till the metal solidifies in the mold.

is a widely used non-expendable process, for casting products that have excellent details and surface finish.

it is ideal for quickly and economically producing numerous fully functional, fragile in metal or plastics.

• Achieve a competitive edge with faster "time to market" capabilities

• No costly metal tooling required• Simple to use technology• No heavy mold cover plate – to handle each cycle

• No lift-over of molds• Parts of any complexity can be handled

limited in a lot size and complexity only Zamak can be used as material as it has a very low melting point.(Zamak means a zinc diecasting alloy of relatively good strength and hardness )
