Pipe bending machines can bend any type of metal pipes irrespective of the material or size and these machines range from handheld machines, hinged devices as well as large sized hydraulic powered machines. There are different processes used to bend metals. You can find pipe blending and rolling service service online.
Given below are some of them.
Press bending is used on cold tubes and here a die that is in the shape of the bend is used to press on the pipe and this in turn forces the pipe to be shaped in the form of the curve. However in this method, the pipe does not have any support inside and due to this there are chances of the metal getting deformed. So press process works best when uniform cross section in the pipe is not required.
Rotary draw process
Rotary draw is a process that offers you precise finish and this process uses die sets which has two parts namely the former die as well as the counter die. The shape is created by the former die and counter die pushes the material into the former die. These benders can be programmed to store various bend jobs and this process is used to bend pipes for motor vehicle roll cages, handles, handrails and more. They also create perfect bends when the right die sets are used to create bends.
