Flow Forming Center

Leifeld FFM 623-5

The flow forming center is particularly suitable for rolling out cylindrical rings which are then finish-formed to weight-optimised truck rim rings. Starting parts are cylindrical rings round-bent from a sheet strip, butt welded, burred and expand-calibrated.
