The Swedish group is transferring the production of high-tech seals to its new site in Casablanca.
The appeal of the national industrial hub to major global equipment manufacturers has reached a new strategic milestone. On Tuesday 10 November 2026, the Swedish industrial group Trelleborg officially announced the transfer to its Casablanca factory of the manufacture of state-of-the-art sealing components for the Boeing 737 MAX and 777X aircraft families. Located at the heart of the Midparc free zone, in the immediate vicinity of Mohammed V Airport, this industrial facility – which was inaugurated last June – produces technical polymer seals designed for use in the American manufacturer’s fuselage structures, wings and engine nacelles. These high value-added components meet extremely stringent tolerance requirements to withstand the mechanical stresses and thermal variations encountered during flight. This operational decision forms part of the strategic partnership signed with the US aircraft manufacturer to secure global supply chains from the Casablanca hub.
A state-of-the-art industrial facility integrated into the local ecosystem
The Casablanca site covers five thousand square metres and houses a research laboratory dedicated to materials testing and the development of bespoke solutions. Building on the successful experience of its first automotive site, which opened in Kenitra in 2021, the Swedish manufacturer is strengthening its regional presence and plans to reach full operational capacity within two years. To support the ramp-up of production lines, the company is working closely with the Institute of Aeronautical Trades to provide specialist training for local teams. This academic and industrial partnership ensures that professionals develop their skills in machining, assembly and quality control processes in line with international standards.
Benefits for skilled employment and the industrial ecosystem
The expansion of cutting-edge activities within the Midparc cluster generates direct benefits for the country’s economic development and industrial sovereignty. The development of the site will create between 150 and 200 skilled jobs for engineers, technicians and specialist operators in the sector. The integration of this production into Boeing’s value chain reinforces the Kingdom’s reputation as a competitive and innovative aerospace hub on an international scale. By attracting major technological investment and fostering the transfer of know-how, the country is enhancing its human capital, diversifying its industrial exports and strengthening its appeal to global leaders in the aerospace sector.
