Sub-assembly for aerospace


In the interest of outsourcing a complete service, many customers ask us to deliver full mechanical assemblies.

To this end, Masselin has a workshop for machining and mounting of equipment, which together with the rest of the factory allows us to offer a fully integrated package of springs and complex assemblies with elastic function..

Special springs,  and more specifically spring based mechanical assemblies, incorporate other mechanical parts than traditional helical spring.

Our experience in the aeronautical sector has given us a good working knowledge of special processes like : gluing, clamping, mastic application, crimping.

Our competence spread over many levels :

  • Calculation of springs and full sub-assemblies
  • In depth kowledge about steel and alloys
  • Manufacturing capabilities
  • Assembly

Ressorts Masselin's success in sub-assemblies applications is due to our ability to combine design, prototype manufacturing with complete inspection along with series production.
