Centrifugal Casting – A Manufacturing Method for Highest Demands The molten metal is casted in a fast rotating cylindrical die. The released centrifugal force generates a pressure on the liquid metal which is approx. 30 times higher than under normal gravity conditions. Directional solidification of sound metal progresses from outside toward the bore. Oxides and impurities are forced inward, metal is forced centrifugally to outside. Impurities are concentrated in the bore and will be removed by machining. The result is a defect-free structure of the cylindrical casting. In comparision with static casting method the mechanical properties are improved by same chemical composition of the alloy.

MMG Centrifugal Casting
History And Present Time Casting of alloy has started on today’s place of Mecklenburger Metallguss GmbH (MMG) in the year 1890, already.
Until 1945 there were manufactured parts made of cast iron for the increasing mechanisation of agriculture and for small machine factories.
The development to a leading foundry for copper alloy started in 1948.
Since this time there were manufactured castings with casting weights from 1 kg up to 200 t.
The world’s biggest fixed pitch propellers are casted in MMG workshop.
The manufacturing of centrifugal casting began in Waren in the
year 1960, in particular with the casting of shaft liners for ships.
Since then, the range of products was permanently extended in respect to dimensions as well as type of material.
The in-house research and development department guides the innovation of materials and casting technology.
In the daily practice we guarantee quality on highest standards.
Our well equipped laboratory determines the characteristic value of the material, optimizes and documents it for the customer.
MMG`s centrifugal casting team is able to satisfy the requirements
