2-14 Path Once again, Ressorts Masselin will be present at  Industrial Valve Summit in Bergamo on May 24th and 25th : The intenational meeting of  valves and actuators manufacturers is the place to be if you are looking for the best suppliers of valves and its components.

On this occasion, we will be proud to exhibit the biggest spring in the world, coiled from a 97mm diameter and 14 m long bar made out of chrome steel. The inside diameter of this part is 550 mm, its free length 1.500 mm and its weight 750 kg !

Despite its very large size, it will have to keep tolerances as tight as the small springs and will undergo the most severe controls.

Come and meet us  : Hall A, Stand 98

Spring for Independant Suspension of Armored Vehicles


Masselin is a supplier of suspension elements for armored Vehicles, springs and torsion bars.

These springs feature variable pitch and thus a double stiffness, this allows for better grip when driving on rough terrain and a higher stiffness in the event of an impact.

Ou Dual - coated expoxy - polyester paint protects against corrosion even in aggressive environments.




Approval Airbus


We just received the AIRBUS approval to carry out the passivation type E12 NADCAP.

This process ensures the removal of ferritic contaminants from the surfaces of stainless steel parts for the purpose of improving corrosion resistance. This internal process has recived the Nadcap approval according to the aeronautical standard AS 7003. (Repository : AMS2700 Méthod 1 Type 6 - Chemical Process - Passivation). pdf
