Sweden’s Trelleborg Sealing Solutions has announced it is transferring its aerospace production supporting the Boeing 737 MAX and 777X to its new facility in the flourishing aerospace hub of Casablanca, Morocco.
Inaugurated in June 2026, the new 5,000 square meters/53,820 square feet state-of-the-art production facility in the strategic aerospace hub of Casablanca boosts capabilities and capacity for major customers like Boeing.
Gordon Roper, President of Global Aerospace, says: “Casablanca’s development into a significant hub for aerospace led to Trelleborg developing Morocco’s first production facility focused on polymer seals for key aerospace customers.”
“The transfer of our production supporting the 737 MAX and 777X is further evidence of our support for the region’s growing aerospace eco-system,” he underlines Mr. Roper.
Building on its long-standing relationship, Trelleborg signed a memorandum of understanding with Boeing two years ago. From Casablanca, Trelleborg will supply a range of aerospace sealing solutions including seals for airframes, nacelles and wings, which support the Boeing 737 MAX and 777X programs.
“Trelleborg has in recent years developed strategic regional investments that bring us closer to our key customers, increasing supply chain resilience,” adds Roper.
Situated in Casablanca’s Midparc Industrial Freezone, close to Mohammed V International Airport, the new Trelleborg facility is creating over 200 highly skilled jobs. It also strengthens Morocco’s position in the global aerospace supply chain. Focused on high-value, technically demanding applications, the facility is fully integrated into Trelleborg global programs.
The facility houses a fully equipped advanced material laboratory to support the ongoing testing and development of specialized materials for the global aerospace business.
Trelleborg’s airframe seals are typically used for aerodynamic sealing of doors, canopies, hatches and panels, and Trelleborg is the largest global producer of aerospace window seals. These seals can be reinforced to provide the load, deformation and wear properties required for variable working conditions in both static and semi-static applications.
They offer low friction, good abrasion resistance, high flexibility and long life, and can be combined with composite or metal structures to limit part count and ease installation.
