Специальные профили из титана и 17-4 PH для колец реактивных двигателей, направляющие для крепления сидений и других конструкционных деталей.

Aeronautics require high specifications with tight tolerances, certifications, continuous product
development and a perfect service. This is the reason why CEFIVAL follow up aeronautics products by
carrying out a 100% inspection. Our R&D Department works on developing materials and the
requirements of our customers are always in the forefront of our sales team’s minds. The products we
manufacture can be found either in the structure of the plane or in the jet engine itself as rings.

MANUFACTURING RINGS FOR AIRCRAFT ENGINES

As long-standing partner of engine manufacturers, CEFIVAL equipped its plant with finishing facilities for
rolled or hot extruded bars dedicated to the aircraft industry.

The engine rings workshop is equipped with efficient bending and flash welding facilities as well as many
presses enabling improved forming of each part.
