Roller Forming is a non-impact process using a spinning Roller-head with two or more rollers to apply a symmetrical force to the part. Roller forming is used for flaring, forming a lip, crimping, or forming a groove in cylindrical parts too large for other processes. Assembly applications include: water pumps, bearings, ball joints, air bag canisters, electrical sensors, fuses, solenoids, and parts where a groove or lip is needed, such as sealing the end of a tube.
As a general rule, 90% of Roller Forming applications are between 3/8" and 6" inches in diameter. Wall thickness can vary from 1/32" to over 1/4" of an inch depending on the type of material. The Roller-head RPM and advance rate are controlled by Orbitform's standard Powerhead to precisely form the material. The Powerhead can also be configured with an integrated Load Cell and LVDT for process monitoring and control, along with a Thru-Spindle Pressure Pad for part clamping during the forming process. For static Roller-heads, typical cycle times range from 3-5 seconds depending on the application.
Roller Forming can:
- Replace crimping
- Cold form with precise control
- Satisfy cosmetic requirements on assembled parts
- Form both inside and outside diameters simultaneously
- Be used in work cells and automated assembly

Orbitform Group's line of Rollerform articulating rollerheads combine the rotating forming action of a fixed center rollerhead with a three jaw gripping motion. This specialized type of forming is unique in industry.
Orbitform Group's line of Fixed Center Rollerheads intersect the workpiece on an exact contact line, gradually forming material to the desired shape as the powerhead advances.
