Roll Bending Machine
The roll bending machine is suitable for rolling processing of pipes and profiles with a large bending radius. It can process product shapes such as arches, coils, etc., and is mostly used in industries such as bridges, stadiums, engineering buildings, and street lights.
The most common type is 3 roller pipe bending machine. There are also 7 rollers and 9 rollers bending machine.

Advantages:
A variety of tube radii can be performed on the same machine including variable angles.
Sections such as pipe, bars, and angle can also be formed with this method
Disadvantages:
Slower process as each tube is manually processed with difficulty in obtaining exacting results.
Thin-walled tubing can easily collapse if the bend radii are too small.
Accuracy and repeatability are not very good
The above are the four types of pipe bending machines, under each type, according to the maximum bending capacity, the pipe bending machine is divided into several models, so when buying a pipe bending machine, if you do not know the specific model you need, it is better to provide product drawings to suppliers and ask them to recommend the right model for you.
