Some manufacturers produce centrifugal components, including some with O.D shaping, in dies rotating about the vertical axis. In addition, some manufacturers offer near-net shaping which combines the benefits of centrifugal casting with O.D shaping, perhaps even with the finished detail of an investment casting. There are two types of centrifugal casting processes – vertical and horizontal. are machined away, resulting in a defect-free structure without cavities or gas pockets. Once the casting has solidified, the part is removed from the die and residual impurities in the I.D. towards the bore, while the less dense material, including impurities, “floats” to the I.D. Directional solidification of sound metal progresses from the O.D. The combination of this applied pressure and the engineering mechanics of controlled solidification and secondary refining produces components of superior quality.Īs the die begins to fill, the more dense molten metal is forced to the wall of the spinning die.
The die may be oriented either on a vertical or horizontal axis depending on the configuration of the desired part.īy spinning a mold while the molten metal is poured into it, centrifugal force acts to distribute the molten metal in the mold at pressures approaching 100 times the force of gravity. The centrifugal casting process steps begin with molten metal being poured into a preheated, spinning die. It has also proven to be a cost-effective means of providing complex shapes with reduced machining requirements and lower manufacturing costs as compared to forgings and fabrications. As a result, it is the technology of choice for applications like jet engine compressor cases, hydro wear rings, many military products, and other high-reliability applications. Centrifugal casting is a process that delivers components of high material soundness.
