Mecklenburg Metal Casting

What Mecklenburg Metal Casting does

Mecklenburger Metallguss GmbH (MMG), headquartered in Waren (Müritz), Germany, is a privately held manufacturer and world market leader in the design and production of large marine propellers, with roots tracing to a foundry established in 1874 and continuous propeller manufacturing since 1948. The company designs and casts propellers weighing up to 160 tons and up to 11.6 meters in diameter in copper and aluminum alloys, operating one of the world's largest melting capacities for these materials (including the world's largest induction melting furnace for copper alloys at 80 tons). Its proprietary Multidata Design Concept (MDC), co-developed with TU Hamburg-Harburg, is described as unique among propeller manufacturers worldwide, and is supported by an integrated digital stack comprising Numerical Propulsion Simulation (CFD-based), Optical Precision Measurement (1/100mm accuracy), Numerical Controlled Processing, the Virtual Contact Test (classification-society-recognized), Power Train Calculations with FEA, and a Hybrid Manufacturing Process combining XXL 3D printing with arc welding. MMG's product portfolio spans newbuild propellers (espro and espro silent lines), the patented MMG-Escap energy-saving cap, redesign/retrofit propellers, centrifugal casting (bushings/rings), and special castings (pump impellers, tidal turbines, ballast water reactors).

The business is run on a project-based, quote-driven enterprise model with five revenue streams: marine propeller manufacturing, centrifugal casting, special casting, repair and after-sales services, and engineering/consulting (including EEXI compliance advisory). MMG sells globally through a network of agencies and representatives across Brazil, China, France, Greece, India, Japan, Croatia, South Korea, Taiwan, Turkey, the UAE, and Cyprus, supported by mobile service teams for worldwide repair work. The company is led by Managing Directors Dr.-Ing. Lars Greitsch (Head of Research & Innovation) and Katrin Beuster (Head of Human Resources), employs more than 200 people including ~10 apprentices, holds DIN EN ISO 9001:2015 certification (Lloyd's Register), and is certified by all major classification societies. Reference customers include CMA CGM (ultra-large containerships), Maersk (Emma Maersk, 131-ton propeller), and AIDA Cruises; cumulative retrofit deliveries exceed 400 propellers with reported fuel savings of 6-14% when combined with MMG-Escap.
