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.

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 force at identical or similar dimensions
