Spinning machine designed for hydrogen tank production

Leifeld Metal Spinning AFC

Leifeld Metal Spinning GmbH has introduced the Aluminum Forming Center (AFC), which forms the ends of aluminum cylinders for hydrogen storage. It uses a necking-in process that optimizes the entire neck area in its wall thickness profile during the forming process for long-term durability.

In addition to the standard necking-in machine, the manufacturer offers a machine that combines necking-in and flow forming technology to form the entire pressure vessel body and the necks.

Two options are available for preheating the material: gas burner or induction system. The temperature can be adjusted precisely to the desired level to prevent coarse grain formation and preserve the material’s strength. Once the pipe ends have been heated, the material is necked in. The process is completed by controlled loading/unloading and automated programming.
