I know cookware is routinely pressure die cast. But has anyone come across a pressure die cast pressure-cooker? Given that there will be flanges and undercuts to ensure sealing with the lid, will it be possible to manufacture pot and lid by the die-casting process? Most of the pressure-cookers I have come across are made by deep drawing for the pot and shallow drawing for the lid, with another operation to form the flange and the formed feature to help with locking. 'pressure cookers' may also be called 'pressure pots' depending on which country you are in. Thanks in advance for the help with the responses.
