Hemming is a technology used in the automotive industry to join inner and outer closure panels together (hoods, doors, tailgates, etc.).
The accuracy of the operation significantly affects the appearance of the car’s outer surfaces and is therefore a critical factor in the final quality of a finished vehicle.
The process uses traditional hydraulically operated ‘stamping presses’ to hem closure parts, and, being the last forming process in stamping, it largely determines the external quality of such automotive parts as doors, hoods, and trunk lids.
Tabletop hemming machines are utilized for the manufacture of medium to high production volumes, with the ability to achieve cycle times as low as 15 seconds.
It uses a standard industrial robot integrated with a roller hemming head to provide a flexible method for forming closures.
