Mollificio Bordignon
For more than sixty years, MOLLIFICIO BORDIGNON has been a trusted name in spring manufacturing—producing a wide range of high-performance springs in different wire diameters, shapes, and materials, all compliant with international standards.
A pioneer in quality certification, MOLLIFICIO BORDIGNON was the first in its field to achieve UNI EN ISO 9002 certification in 1995, later advancing to UNI EN ISO 9001:2000, 9001:2008, and 9001 & 14001 (2015 Edition) standards. The company’s environmental management system has also been certified since 2007 under UNI EN ISO 14001.
All production takes place entirely in-house, with every step undergoing meticulous inspection to ensure consistent quality and full traceability.
MOLLIFICIO BORDIGNON commitment to excellence is driven by continuous research into new materials and surface treatments, paired with rigorous performance testing under diverse operating conditions. This dedication delivers springs that combine exceptional reliability, superior performance, and extended service life.
