Sogefi is a leading manufacturer of parabolic and conventional leaf springs. The wide product range is suitable for all sorts of vehicles, from the lightest utility vehicles to the heaviest trucks, built for long-haul or off-road missions.
After the rolling and forging operations, the spring leaves are quenched and tempered to achieve the required mechanical properties. They are then shot-peened to increase the fatigue life. Magnetic particle inspection tests are carried out when required.
Using a specific process, Sogefi can manufacture high stress springs. The high performances obtained enable a weight reduction and, as a result, allow the vehicle payload to be increased. All the major European truck manufacturers have now opted for this technological solution.
