Metal casting is one of the basic manufacturing processes. Cylindrical and symmetrical hollow castings are produced by true Centrifugal casting. This casting technique has application across a wide range of industrial and artistic applications. Complicated shape can be easily cast using this technique. Among different casting technique centrifugal casting is widely used to production of cylinders like components. In this technique internal core is not required to get hollow cylinders. The aim of this study is to examine the influence of rotational speed in centrifugal casting. Focus is placed on interplay between the thickness of fluid cylinder, viscosity of the fluid, diameter, and rotational speed of the mold. Geometric model of mold is generated and analysed for different casting thickness. Cold modeling experiment is conducted using fluids with different viscosities for different rotational speeds. Effects of diameter and speed of rotation have been examined. The results obtained by analysis are compared with experimental results. It is observed that the speed required to form complete cylinder increases with increase in thickness. It is also found that spinning speed required to form complete cylinder increases with decrease in diameter of the mold. The driving force required to lift the fluid decreases with increases in thickness if fluid cylinder and decrease in diameter of the mold. The speed of the rotation varies with metal, alloy and size being cast. The experiments were conducted to study the effect of rotational speed and thickness of casting. Pure Tin, aluminum-silicon alloys (with different composition of silicon) are used for present investigation. Still experiments are in progress.
