Flanging is the bending of sheet edges. The workpiece may have a curved or flat surface, and its edge may be a straight line or curve.

Twisting process design;

• Bendability assessment
• yawning back
• bending force
  It consists of a combination of operations.

Sheet flange operations are generally easier than drawing operations. Often, part flanges are made in molds that do other operations because molds and components are costly.

Steel drums are produced in flange machines. Flanging machines prepare the edges of the drum body for further processing by forming flanges on both sides.

The flange machine is part of the Drum Body Production Line.
