By pushing apart the edges of the material, you can create a split shape resembling a T-shaped cross-section.
When producing a split shape through forging, a large load is required; however, with flow forming, it is possible to shape from a disc with a small force. This allows for the shaping of pipes in sizes that are not commercially available.

Company information
Nippon Spindle Manufacturing Co., Ltd. is a leading manufacturer of flow forming and metal spinning machines. Our technologies enable the production of axisymmetric components through incremental forming processes, offering an alternative to conventional forging and stamping methods. Because forming is performed gradually with relatively low forming forces, large presses and extensive production lines are often unnecessary. Flow forming technology can help manufacturers reduce capital investment while achieving lightweight and thin-wall designs with improved material utilization. It is particularly suitable for localized manufacturing, flexible production systems, and small to medium production volumes. If you are facing challenges such as high machining costs, excessive material waste, or demanding weight reduction targets, our flow forming solutions may provide an effective alternative. We support customers not only with machine supply, but also with process evaluation and feasibility studies based on part drawings and production requirements. Contact us to explore how flow forming technology can improve your manufacturing process and reduce production costs.
