Tube bending

»Tube bending« is a collective term for various forming processes – also referred to as »bending methods« – which cause tubes to plastically deform by means of force. Cold bending is characterized by achieving the deformation of the tube below the recrystallization temperature of the material. In contrast, hot bending is characterized by the section to be deformed being inductively heated prior to bending, thereby aiding the deformation.

 

Tube bending
at Härtwig Maschinenbau

We use a mandrel bending machine to fabricate bent tubes with a maximum diameter of 60 millimeters. The mandrel bending method is a cold bending process which utilizes a mandrel and a forming die to deform the tubes. The bending radius is defined by the die.
