ONDUFILTM spring washers are round elastic parts, in the same family as our waved spring washers, Belleville or diaphragm spring washers. They are produced using a new manufacturing technology that entails simultaneously winding and rolling a flat wire corresponding to the width of the coil.
Based on this technology, ONDUFILTM spring washers offer a solution for new requirements including ever smaller dimensions, ever higher deflections in elastic deformation and increasingly varied stiffnesses.
Borrelly has incorporated two additional structures to quickly and accurately meet your requirements:

|
- An engineering department with high-performance computational software.
- A production workshop for ONDUFILTM spring washers, equally capable of producing prototypes and large series production runs.
