Radial riveting gets its name from the fact that the flow of the metal structure occurs primarily in the radial direction rather than in the tangential direction of the circle. It is performed in thousands of cycles per second, gradually shaping the rivet head from the center outward. As a result, the riveting force required for the deformation of the rivet is minimized. 【Features】 ● Low thrust forming ● No heat generation ● No need for workpiece fixation ● Various shapes can be formed ● Prevention of material property degradation ● Prevention of chip generation ● Quality assurance possible (optional) ● Beautiful finish of rivet heads ● High durability forming achieved ● Low riveting load on components *For details, please download the catalog.
