Welding process is not necessary.
You can bend tube in 3D freeform figure.
Bending radius can be set freely.
You can set bending radius and angle freely because NPB series does not use roll die, This model enables more than 180 degree bending, large radius bending, spiral bending and so on.
Continuously changing radius bending is also OK.
You can get such shape of tube as its radius changes continuously. Due to CNC control, you can change bending radius and bending direction in X-axis and Y-axis freely. So, you can make 3D freeform figure easily.
Smooth and even finish with little section distortion
As the bending section of tube is securely guided by the die, accurate roundness and a smooth and even finish can be obtained. In our bender, tube is pushed into die. So, unlike a conventional tube bender, wall thickness reduction at the back side is very small. Due to motor drive, operation sound is very calm and high speed operation such as 10m/minute is realized.
Specification of NPB series
Cooling Tube for Compressor
A tube for heat exchange is a copper tube bent in 3D and it wears a lot of radiation fins tightly secured. In the case of using an conventional tube bender, it is difficult to set fins because the bent tube is deformed. If using fins with a larger inside diameter, they can be set smoothly but they are not set tightly. By using NPB series, you can set fins tightly and easily, and still adopt freer 3D shape because the deformation of the tube is slight.
Cooling Tube in Atomic Power Plant
A tube bent with this model is suited to high pressure use such as cooling tube in atomic power plant in which the strength of the tube is important, because the back side thickness of the bending portion does not become thinner, unlike tubes bent by conventional benders. You do not have to worry about leakage problems because you don't have to use a lot of elbows.
Exterior Design Products and Monuments
3D curve design which is comfortable to human became to be required in fences, benches, monuments and so on which are located in public buildings and squares. When manufacturing these products, you can make a good use of merits of NPB series - 3D freeform design and beautiful bending finish.
Because NPB series can cut out restraint in the design, such products can be developed as reflect free ideas of designers fully. In regard to chairs made of tube, the chair back is of 3D complex curve according to the requirement of human engineering. In case of using conventional tube benders, chair backs required two processes; bending with a tube bender and, after rotating 90 degrees, bending with a press machine. However, NPB series does these processes in one operation and increases productivity and quality of appearance drastically.
Boat Bow Rail
Large and 3D shape like Bow Rail was bent with hand by craftspeople until now.
3D curve design became to be required even to bicycles. You can give additional value to the products by differentiated design.
Playing equipment and others
Because of reduced restriction to design, you can swell your idea. Playing equipment is a typical case. Ideas have no limits.
