Düker Technology – Tailor-Made Centrifugal Casting Machines for your Application


In 2014, Küttner Centrifugal GmbH & Co. KG, a joint venture with DÜKER was fully integrated in KÜTTNER. DÜKER centrifugal casting technology is worldwide in operation for more than 60 years.

Küttner in Karlstadt projects, plans and designs complete centrifugal casting machines and plants with associated production lines, tailored to the needs of our customers.

Küttner Centrifugal Casting - with DÜKER Technology – trim cast iron into shape. Our production plants are used worldwide for the manufacture of pipes, cylinder liners as well as other rotation-symmetrical castings made of different materials.

The centrifugal casting process is based on the principle of mould filling through centrifugal forces. The melt runs through a casting runnel into the mould rotating horizontally or vertically. The inside contour of the centrifugal mould images the outside radius of the rotation-symmetrical casting which is produced. The inside diameter of the casting is defined through the melt quantity. The melt is pressed to the inside of the mould by the centrifugal forces and solidifies there. The casting is drawn out of the mould while still glowing.

Free Shaping:

Centrifugal castings are not limited to cylindrical parts. Centrifugal sand casting uses sand packages inside a centrifugal casting machine. This process is also known as semi centrifugal casting. Advantages out of two casting processes can be combined: the good molding properties of sand combined with the high G-force mold filling and feeding of the centrifugal casting process.
