Rollerforming
Orbitform's Rollerforming process 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 an exact contact line, gradually moving material to the desired shape, as the powerhead advances.
Rollerforming can displace large diameters and thin wall materials, often difficult with other fastening methods. The process is advantageous when used to roll or close the lip. Rollerforming can be used in applications where rollers articulate as well as rotate, allowing for access into grooves and other areas.

Forming a curl or lip with Rollerforming takes less force than normally required for straight crimping or pressing.
Rollerforming replaces crimp tooling which can be problematic in appearance, process control and reliability. It is strong for critical automotive applications of metal and aluminium, and versatile for appearance sensitive plastic parts.
Orbitform's rollerform process can:
Crimp and seal using multiple rollers
Cold form with precise control
Satisfy cosmetic requirements on assmbled parts
Form both inside and outside diameters simultaneously
Be used in work cells and automated assembly operations
