Quality and Certifications

A fully certified environment.



The company’s production process is carried out entirely in the Campello sul Clitunno plant in Umbria, where they take care of every detail without outsourcing delicate manufacturing stages to third parties.

Specifically, MTU produces mechanical seals and rings in silicon carbide, carbon and PTFE-based composite materials (the latter under the registered trademark Mecflon), all of which feature high tribological characteristics capable of enhancing the performance of engines and machines worldwide.  All the rings are checked with special automatic vision tools, both at the acceptance stage and during the process. During the moulding stage, they are assembled on semi-automatic lines, where manual checks certify that the chain is working correctly. All the rings undergo testing under critical conditions and subsequent commissioning before the packaging stage to ensure there are no oversights.

The company's certified Quality Management System complies with ISO 9001 standards. We are also certified with IATF 16949 for the automotive sector and EN 9100 for the aerospace sector.
