Sub-assembly for industry

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

Our competence spreads over many levels :

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

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 :

  • Conventional springs (compression, traction, torsion)
  • Machined springs
  • Machining and mounting of mechanical end fixtures
  • Assembly of complete mechanical sub-assemblies

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