FIELD: process engineering.
SUBSTANCE: claimed set of inventions relates to metal forming, particularly, to production of two-piece metal vessels. Metal sheet is dawn to bowl with side wall and stretch-wrap forming with pressing of ring area at one press. Then, redrawing of bowl is performed along with its necking for stepwise bowl diameter increase and/or bowl sidewall height increase, respectively. Said press comprises drawing means, pressing element, stretch-wrap forming means, redrawing and/or necking means.
EFFECT: decreased base depth compared with inlet depth of sheet metal.
