Accroche

For many years now, Masselin has specialised in the manufacture of elastic parts with high added value, which can adapt in an aggressive environment and must respond to demanding specifications, such as very high temperatures, strong and repeated vibrations, and severe constraints at a reduced size.

SCOPE OF

APPLICATION

Our parts are used in the following applications :

  • Ski lifts
  • Steel mills
  • Mines and quarries
  • Agriculturals systems
  • Construction tasks
  • Robotics

Our design office will help you develop new, tailored parts, basing its suggestions for a spring or anti-roll torsion bar on your requirements.

FURTHER TECHNICAL INFORMATION

Parts undergo testing in our workshop to ensure that they meet the strictest requirements for the greatest reliability :

  • Hardness testing
  • Size testing
  • Lengths under load and vertical stiffness
  • Non-destructive test (magnetic particle inspection, dye penetrant inspection etc.)
  • Metallographic testing (metallurgical structure, decarburisation etc.)
  • Shot peening intensity measurements
  • Failure analysis with research into the cause of rupture, if required

Raw materials :

We use spring steel that is developed in accordance with the standard EN10089, mainly 51CrV4 and 52CrMoV4, and if requested, the bars are subjected to ultra-sonic testing to detect any internal faults. For smaller springs, there is the option of using stainless steels, nickel-based alloys (Inconel, Nimonic etc.), titanium (Grade 5 Ti-6Al-4V), copper beryllium (CuBe2) etc.

Protection against corrosion :

We have a powder coating facility and a liquid paint plant to ensure that our products are treated with the best possible protection against corrosion.

Double-layer paint provides 1500 hours of resistance to salt spray.
