The present disclosure relates to a battery tray for an electric vehicle, manufactured as a hot-formed and press-hardened component from a sheet steel blank, having a base and side walls rising from the base with a flange running around the top of the battery tray and projecting outwards, characterized in that the side walls run on the longitudinal sides of the battery tray and the side walls run on the transverse sides of the battery tray at an angle of greater than 1 relative to a vertical, and in a respective corner region the base of the battery tray merges into a curved surface in such a way that a transition radius of the curved surface to a transverse side wall is formed and a transition radius of the curved surface to a longitudinal side wall is formed.

To suppress warping at a bottom of a workpiece when manufacturing a bottomed box-section cylindrical container by molding a workpiece from a flat plate state to a box-section cylindrical shape state having a bottom by performing multiple press-drawing steps by using multiple molds each having a long-hole-shaped shaping hole. A first press-drawing step is performed using a first mold having a first shaping hole having a long hole shape. A second press-drawing step is performed using a second mold having a second shaping hole having a long hole shape, and is configured as a next press-drawing step after the first press-drawing step. The first shaping hole is formed with a larger dimension in a width direction perpendicular to a longitudinal direction than the second shaping hole, and is formed tapering inward in the width direction from both end sides to the center side in the longitudinal direction.

An embossed head for an end of a tank is disclosed. The embossed head can include one or more embossed features. The embossed feature(s) can extend generally upward or generally downward. The embossed features(s) can include an annular emboss. The embossed head can provide similar resistance to deformation as traditional heads while requiring less material as compared to such traditional heads

A mould for processing a metal panel by means of a hydraulic press includes a forming punch and a forming die, provided on their operating surfaces with corresponding hole patterns, a set of tubular deep-drawing punches disposed in the forming punch and movable relative thereto to protrude through its holes, a set of tubular deep-drawing dies disposed in the forming die in correspondence with its holes, and a set of blanking punches sized to be smoothly guided along the axial holes of the deep-drawing tools. The relative method of operation involves sequentially closing the mould, lowering the deep-drawing punches, lowering the blanking punches, raising the deep-drawing punches, raising the blanking punches and opening the mould.

Provided is a can container including a reduced diameter portion and a can barrel portion, in which the amount of a lubricant present at the reduced diameter portion is equal to or less than 2 mg/can. Also provided is a manufacturing method for a can container. The manufacturing method includes: a forming process of forming a can body having a tubular shape from a sheet material including a metal sheet and a resin film layer covering at least one surface of the metal sheet or from a sheet material including a metal sheet; a lubricating process of applying a lubricant to the can body formed; a diameter reducing process of reducing a diameter of a part of the can body to form a reduced diameter portion; and a printed layer forming process of forming an ink print layer on an outer peripheral surface of the can body.
