Shot Peening and Painting


Federzinken, allseitig kugelgestrahltKlicken um Bild zu vergrößern

Since the endurance limit and static strength of the spring tines mainly depend on the characteristics of the surface and peripheries of the springs, the Agrartechnik Paul Plate spring tines are shot-peened all around after heat treatment.

The shot peening causes a plastic cold forming of the peripheries of the loaded work piece, which mainly leads to the creation of compressive stresses on highly tempered steel. These compressive stresses eventually lead to a higher lifespan of the work piece.

For the perfect corrosion protection, Agrartechnik Paul Plate spring tines are finally equipped with a dip painting or a electrostatic powder coating (Epoxyd-powder) (Powder coating with an external partner).
