First process for tool-independent tube forming developed

New transfluid-process: Forming with reduction in one step.

transfluid creates new technology for economic forming of individual geometries

In times of ever faster and more complex challenges to the production tool costs are one main cost factor. Nevertheless, it is common in tube forming that the form is mostly depending on the tooling. The only ways to take small influence on the geometry were until now changes in the material length and different strokes. With big efforts and a lot of tools the flexibility and efficiency was missing in the process. That’s why solution finder transfluid has designed a completely new process to form different geometries on different diameters without special, geometry depending tooling.

„For us it’s always very exciting to think a little further and to try out and create new technologies, for applications where the standard technique does not provide a solution,” said Gerd Nöker, Managing Director of transfluid. „And often the best solutions are in some effective details.” For our new method for the tube forming only a very simple clamping jaw is in use. All other tools are independent of the geometry and the diameter of the tubes. “A special feature of the new transfluid forming method is that the clamp length is around 1 x tube diameter. So most of the parts can be formed without using expansive form clamps.

The surface of the forming geometry can be produced with a perfect surface quality – even with rotationally symmetrical elements to create an optimal sealing surface. Where previously especially the reduction of stainless steel was a big challenge, the new developed method is a safe solution. The tools are so completely free from wear.

"Since our tube forming process is used specifically for diameter reduction or for keeping the diameter, it is possible, that before the processing an axial expansion of the tube can be necessary. Of course, high-strength materials and stainless steels as well can be formed as also softer NE-metals, "explains Gerd Nöker.
With its impressive solution transfluid has created a technical way, to manufacture a big range of individual geometries with minimal tooling costs.
