Hemming

Precise hemming technique for top quality and top look of the vehicle.

Promised.

Hemming has been and will continue to be an important part of the manufacturing process. The key here is to master the essential processes:

  1. Roller hemming
  2. Table-Top Hemming, hemming with over top tools

Both table-top hemming and roller hemming can be used for steel and aluminum parts. The choice for one of the two technologies is basically made with the intended cycle times of the vehicle to be produced. In the end, only quality and speed count.

Hemming in car body construction

In body construction, hemming is used in assembly as a follow-up operation after deep-drawing, trimming and flange operations to join class A parts to inner parts for reinforcement. The typical components for this type of joining process are:

  • Engine outer and inner hoods
  • Exterior and interior doors
  • Tailgates with the interior reinforcement part
  • Trunk lids with interior reinforcement part
  • Side panels
  • Fenders
  • Wheel arches

The precision in the hemming operation is particularly important, because it affects the appearance of the surface and the surface quality. This is where NORMATEC company comes into play in the fine tuning of the hemming equipment.
