Centrifugal casting v.s. forging
Forging is one of well-known conventional castings. Comparing with centrifugal casting (spin casting), there are several limitations of forging. Centrifugal casting is much better in many aspects.
The advantages of centrifugal casting have been illustrated on the other article of BLOG.
The comparison – centrifugal casting v.s. forging is shown as follows.

Could produce custom alloys? |
Win ！ Yes, various materials including stainless steel, special alloys…etc can be cast by centrifugal casting. |
There is the material limitation by forging. The price of customization is also high. |
|
Is the quality great? |
Yes, the centrifugal casting products are clean and pure because of the directional solidification and the high speed rotation.
Therefore, the surface is without the porosities and the strength is high by centrifugal casting. |
Yes, the products are also without the porosities by forging. The strength is also high by forging. The grain structure is also directed by forging. |
|
Possible for small quantity order? Competitive price? |
Win ！ Yes, smaller quantity is acceptable and possible by centrifugal casting. |
The cost of mold is high and the price would be competitive only when ordering several tons by forging. |
|
Cost advantage? |
Win ！ Yes, it’s more cost-effective by centrifugal casting once the quantity is not large. Rings and sleeves are also suitable for being produced by centrifugal casting and costs are lower. |
