Centrifugal Casting Process Description:
The Centrifugal casting process delivers product of very high material soundness and material properties, and thus is the technology of choice for applications requiring the most stringent of product reliability.
In the centrifugal casting process, molten metal is poured into a spinning die. The die can be spinning either on a vertical or horizontal axis depending on the configuration of the desired part. Ring and cylinder type shapes are cast vertically; tubular shapes are made with the horizontal centrifugal process. Either process may be used to produce multiple parts from a single casting. External structures and shaping can be cast in place to significantly reduce post-processing including machining or fabrication.
Because of the high g-forces applied to the molten metal in the spinning die, less dense material, including impurities, “floats” to the I.D. where it is subsequently removed by machining. Solidification is managed directionally under pressure, from the O.D. to the I.D., avoiding any mid-wall shrinkage, leaving a defect-free structure without cavities or gas pockets.
When to use Centrifugal Castings:
Symmetrical parts that can rotate on an axis
Sand Casting (Static casting) material properties are inadequate
Centerline shrink is an issue using other casting processes
Limited I.D. features
Large parts, up to 135,000 lbs or more
Cylindrical parts requiring near net shaping

Do you have a complicated machined hog-out or fabrication that may lend itself to conversion to an alternate process? Nearly all of MetSource’s success stories are centered around converting a product from one process or multiple processes to a streamlined manufacturing process that improves the product Quality, Cost and / or Lead-time.
Material Process Selection
Do you have a part design but want a Solutions expert to advise optimal process to produce your part? Subtle changes in part design can optimize process manufacturability to reduce cost, increase part quality and / or increase throughput.
Do you want to speak to a Metallurgist regarding a part and environment to help with material selection? Alloy selection can greatly affect overall cost and part manufacturability.
