Foundry - Quality casting first time right

With one of the world's largest melting capacities for aluminum and copper alloys, we cast with the highest level of homogeneity of the molten material in the most powerful induction furnace systems.

Capacities

We offer manufacturing capabilities for components up to:

Diameter: 11.600 mm
Final weight copper alloys: 160 t
Final weight aluminum alloys: 70 t
Annual capacity: 14.000 t

Casting

Only a flawless casting piece guarantees a long lifetime of the propeller. Already beforehand MMG simulates and analyses the casting and solidification process. With the help of the largest medium frequency induction furnace in the industry and the provision of extensive services we ensure highest quality and security.

Moulding

More than 20 molding stations are used simultaneously to produce the castings. A crane capacity of 3 x 160 tons enables even the heaviest castings to be handled without difficulty. The know-how of our employees is supported by state-of-the-art computer technology. The latest software applications enable us to simulate the casting processes as well as the solidification behavior of a casting. The exact material analysis is monitored and documented in our in-house laboratory.
