Air bending is performed using a press brake where a punch presses sheet metal into a V-shaped die. The metal is not fully forced into the die, allowing the bend angle to be controlled by adjusting the punch depth.
This method provides excellent flexibility since the same die can create multiple bend angles and radii. However, because the sheet is not fully pressed into the die, springback may occur. Modern machines use laser measuring systems to ensure high precision.
Bottom bending also uses a punch and a V-shaped die, just like air bending. The key difference is that the punch pushes the sheet metal fully into the die instead of partially bending it.
Because the metal is pressed completely into the die, this method requires more force and brings the sheet into full contact with both the punch and die, delivering tighter control over the final bend angle.
The biggest advantage of bottom bending is improved accuracy with significantly less springback. However, it requires changing dies for different angles, and the higher pressure can increase machine wear and maintenance.
