Flow Forming
The flow forming is based on the rolling / roller spinning technology. The main difference is that the tool is not a roller, which moves along a specific contour. It is more about a pot-shaped tool with an incorporated forming shape. Parts produced with this technology have to be rotationally symmetric.
Advantages of Flow Forming
- Quantity reduction of single components: A significant advantage of the flow forming process is the fact that the geometry of the tube end can be formed to nearly every shape without the help of any supplementary material. The flow forming technology allows for a gas-tight closing of tubes without supplementary material, which results in a tremendous cost reduction for stock-keeping and provisioning of single components.

Tolerances: Despite the fact that flow forming is a hot forming process, this technology is able to achieve a tolerance of +/- 0.1mm in length and, based on the part design, also a tolerance of max. +/- 0.1mm in the diameter.
