Rotary Draw Bending

The most common form of bending is ‘Rotary Draw Bending’. This is the method that most manufacturers will use when manipulating tubes, in order to bend precisely, and with the most consistency. Rotary draw bending allows for high quality bends to be produced, even when bending thin walled tubes, and/or using a tight bend radius.

Rotary Draw Bending requires a complete set of tooling in order to execute properly. The tube is gripped and held in place between the Clamp Die and the Bend Die, with further support applied to the outside of the tube using the Pressure Die.

In some situations, a Mandrel is used to support the tube from the inside, and a Wiper Die can be used to support the inside of the bend, sitting opposite the Pressure Die.
