Quality is cast in rotation
Centrifugal casting is a process used for components that must function continuously under pressure, high temperatures, friction, or corrosion. The key advantage lies in the way the material solidifies: molten steel or iron is poured into a rotating mold and solidifies due to the rotation at approximately 100 times the acceleration due to gravity.

Due to this much higher density compared to “normal” castings, coarse impurities, slag, and pores “rise” from the microstructure to the inner surface. Solidification proceeds from the outside in, pushing microporosities and impurities ahead of it. This results in a particularly dense and pure microstructure, whose properties are largely comparable to those of forged materials.
The result is a workpiece with high purity and excellent mechanical properties. This is precisely why centrifugal casting is a strong alternative to static casting for many applications and, in many cases, superior to other manufacturing processes in terms of its properties.
The benefits are particularly evident in rotationally symmetric components for demanding industrial applications: from rings, tubes, and rollers to high-performance components such as cylinder liners. Here, centrifugal casting combines material quality with manufacturing efficiency. Because the interior is formed by the process itself, cores are not required for many geometries. This reduces the number of process steps, eliminates typical sources of error, and provides greater flexibility during subsequent machining.
For customers, this means fewer compromises between quality, cost-effectiveness, and delivery reliability. The desired alloy can be tailored to meet standards or specific requirements. The cast blank is then machined into a precise final product – with properties that are perfectly suited to the application.
Centrifugal casting is thus much more than just a casting process. It is a principle of quality: The process uses physical forces to impart purity, density, and strength directly into the material. For industries ranging from mechanical and engine engineering, decanter and marine technology to energy and metallurgical engineering, this is a decisive advantage. After all, in these fields, it’s not enough for a component to simply fit. It must operate reliably over the long term – often under conditions where material quality makes all the difference.
