Passivation of Springs

The passivation process takes place once a spring has been formed, to remove iron contaminants and improve corrosion resistance. After thoroughly cleaning and rinsing the spring to remove residual debris and grease leftover from the manufacturing processes, the spring is immersed in a bath of passivating acid and then rinsed and dried. Our team then uses a special testing process to ensure that the passivation process was completed correctly.
