About Bordignon

MOLLIFICIO BORDIGNON has been manufacturing springs for over 50 years with different wire diameters, shapes and materials, as well as springs conforming to international standards. The high performance of MOLLIFICIO BORDIGNON springs is ensured by rigorous research into new materials and treatments and continuous tests in different conditions of use. 

In 1995 MOLLIFICIO BORDIGNON was the first company in its sector to obtain UNI EN ISO 9002 certification. Superlative performance is achieved by the combination of product quality and proper use

Black Springs


Black springs are produced by means of a new patented cold coiling system using very high tensile steels and special treatment. They provide exceptionally high loads, greater than those available from gas polyurethane springs orBelleville washers of the size.


These springs are easy to fit, simple to use, reliabel  and safe.

They do not require complicating assemblies/fasternings.
They avoid the use of pressure vessels in the die.
The diameters remain unchanged at any deflection
They also work at higher temperatures than those possible with gas and polyurethane spring
The loads do not change with temperature virations.
No protection from contaminants, liquids or metal chips is required
There is no need for maintenance or lubrication.

Greater forecs at identical or similar dimensions


The graph allows an immediate comparison between the maximum forces available, on a same-size basis, with the different spring families: wire, belleveville, nitrogen and polyurethane. In reality, the dimension are not and cannot identical the closet have been considered. The new black series clearly provides greater forces at identical or similar dimension.
