Rollerforming uses multiple rollers mounted on a rotating spindle to gently smooth and form material into a seamless, solid form. The rollers intersect the workpiece on a precise contact line, gradually moving material to the desired shape. The process can replace typical crimp tooling in cases where part appearance or process control reliability is a concern.
Rollerforming is capable of forming parts with large diameters and thin wall materials that may be challenging for other fastening methods. Rollerforming is also advantageous when used to roll or close a lip. For access into grooves and other areas, Rollerforming can be applied to applications where the rollers articulate as well as rotate. Forming a curl or lip with this process often takes less than 20 percent of the force normally required for straight crimping or pressing.
