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
This is Japan Spindle Manufacturing, which produces flow forming machines and spinning machines. Parts that are shaped through pressing and forging can be formed sequentially with small thrust and small machines. This eliminates the need for large-scale line preparation and is useful for local production overseas and the production of small lot parts.
