3) Orientation: spring is a living element whose the specificity is to spread several functions. All technical specifications, shapes, dimensions, tolerances will have an incidence on the expected final functioning. All technical aspects will be interesting only with the taking in account of the tools and final user mounting methods to optimize the cost. Consequenlty, our team participates  easily to the final customer technical requirements.


Formalizing with samples is an essential way of our job. We generally manufacture prototypes before to start the mass production to ensure the representativeness of the offered solution.
