Reducing / Expanding
The tube is held axially by at least two clamping jaws during the forming process. A guided pull-in ring or expanding mandrel is pushed into/over the tube and expands/reduces the workpiece in this way.
Areas of application: Airbag cartridges, shock absorber tubes, chassis parts, steering columns, tube end calibration, tube angling, furniture tubes, scaffolding tubes, and much more.
