New Process Development with Hydrostatically Assisted Two Step Forming
[Introduction]
  • Hydrostatically assisted two step forming was investigated in the present study in order to fabricate automotive part having a complicated shape using Al alloy sheets with a conventional formability which has been known to be quite lower compared to deep drawing steels. We have designed the hydro-mechanical forming in which Al sheet was drawn to a kind of preform step following gas blow forming for final accurate geometry.
[Work scope and main results]
  • Hydrostatically assisted two step forming process development: forming time of less than 10min
