Robotic Roller Hemming Systems

Roller hemming combines standard industrial robots equipped with a standard roller hemming head that follows the contour of the outer flanges of a sheet metal component, optimally hemming it over an inner panel which is precisely nested in a die. Our flexible process offers numerous advantages over traditional techniques including reduced capital investment costs with superior dimensional quality.

Roller Hemming Heads
Valiant TMS has developed standard roller heads for all typical applications.

  • Basic heads (single roller, no load monitoring).
  • Flexible heads (multiple rollers with load monitoring).
  • Custom head design and manufacturing for unique applications.

Prototype Development
The Valiant TMS prototype facility features a fully operational 4-style robotic hemming system that is lead by a team of metal coordination and product development specialists.
