About Centrifugal Casting

Centrifugal force acts to distribute molten metal in the mold at pressures approaching 100 times the force of gravity. Thanks to the combination of this applied pressure, controlled solidification and secondary refining with engineering mechanics, it produces high quality parts. The wall thickness of the material depends on the amount of liquid metal poured and can be adjusted as desired.

When the mold begins to fill, the denser molten metal penetrates the wall of the melting mold. After the casting has solidified, the part is removed from the mold and residual impurities are machined off, resulting in a defect-free structure without voids or gas pockets.

Centrifugal Casting Advantages:

• A clean casting is achieved with simple stock removal, as low-density non-metallic inclusions will migrate towards the inner surface.

• The strength of the casting is high, as the method provides a fairly high casting pressure and therefore good feeding.
• The ability to feed the liquid metal into the mold at high speed allows the casting temperature to be kept lower.

Centrifugal Casting Disadvantages:

• Initial investment costs are high.
• Castings are limited in shape and size.
• It usually requires a small amount of liquid metal at regular intervals, so holding furnaces are needed.
• Alloys of metals with very different melting temperatures and specific gravity are difficult to cast due to stratification during solidification.
