Flow forming is a technique offering a whole range of benefits.
However, flow forming always involves the procurement of a tool. This is viable from small production runs upwards. The greater the required quantity, the more favourable the price becomes, as the set-up costs are only incurred once. Even complex geometries can be implemented. Flow forming involves placing the sheet metal plate in front of the tool and applying a suitable rotary movement and contact pressure. The spot load applied by the pressure roller causes the material to flow and cling to the tool.
This produces seamless shapes to a high degree of accuracy, even with large production runs, as the control engineering used permits the required movement sequences to be precisely repeated any unlimited number of times.
