摘要：
In order to simplify the production of a nigh-resistance bobbin body made of an aluminum alloy, the following process steps are performed: (a) extruding or flow extruding an essentially cylindrical bobbin blank; (b) cutting the bobbin blank to a length including the desired bobbin body length plus an overlength sufficient to form end flanges on the bobbin body; (c) shaping end flanges at both ends of the bobbin body from the overlength portion; hardening the bobbin body; and age-hardening (aging) the bobbin body. Various process parameters are described.
