Features of the 3D pipe bender


	(Pipes can be bent as desired by rotating the ceramic die guide three-dimensionally.)

When you use the 3D pipe bender, the back side of the bended portion does not become thinner, which is caused by conventional bending machines. Thereby, the strength of the pipe can be maintained. The 3D pipe bender allows us to bend pipes three-dimensionally as desired and beautifully. In addition, you do not need metal molds according to different bend radii, helping reduce costs. Unlike conventional bending machines, the 3D pipe bender imposes few restrictions on designing, allowing designers to develop products based on their creative ideas without any compromise. In the past, to bend a pipe into a complex 3D radial shape, it has been necessary to use a pipe bender and rolling mill or press machine in a complex way, which requires many man-hours. With our machine, you can achieve a desired shape with one application, significantly improving the productivity as well as the appearance quality.

Pipe sizes that can be processed

Bend radius

The machine is capable of processing pipes with 19Ø to 42.6Ø. The size that can be processed is determined based on the die guide in stock.

25Ø: t1.5 t2.0 t3.0
30Ø: t2.0 t3.0
32Ø: t2.0 t3.0
34Ø: t2.0
35Ø: t1.5

*We can also accept custom-made sizes.

The minimum bend radii are as follows:
Both for two- and three-dimensional bending,
1 solid tube R=3 folds of the pipe radius
1 clad tube R=8 folds of the pipe radius
As long as the conditions above are met, it is basically possible to bend any tube. However, as for bending with continuously variable R, prior testing is necessary.
