A method of, and arrangement for, producing shaped hollow metal objects by a hot process. A metal hollow semi-finished-product with at least one opening is heated to a forming temperature and placed into a cavity, whose shape corresponds to the desired final external shape of the hollow object. Then the cavity is sealed and water and/or steam is introduced therein. After the final shape of the semi-finished-product is achieved, the semi-finished-product is removed. The cavity is formed by a split mould, whose opening's entry edge has an expanded portion, against which a sealing feature is oriented. The outer surface of the sealing feature is arranged to close against this expanded portion. The sealing feature is also provided with a means of supply of water and/or steam, and a tube through which the water and/or steam is supplied. This tube extends into the interior space of the semi-finished-product, and can be provided with nozzles.

A surgical handheld devices are essentially made up of a device body or main body and of a tubular shaft. In the production of known surgical devices, the tubular shafts are welded to the device bodies. A large number of very complex work steps are necessary for this purpose. On account of the high quality demands placed on surgical handheld devices in respect of mechanical stability and sterility, the weld seam has to meet the most stringent requirements. The invention makes available a method for producing a surgical handheld device, which can be used particularly easily and reliably. This is achieved by the fact that at least one device body and at least one tubular shaft of a surgical handheld device are connected to each other with form-fit engagement by hydroforming.

A method of forming a shaped container may include providing a metallic preform. A first pressure may be applied to the metallic preform within a mold of a shaped container to produce a container part with a partially formed container shape. The container part with the partially formed container shape may then be at least partially annealed. A second pressure may be applied to the container part within the mold to produce a container part with a fully formed container shape.

A system and method of manufacturing a metal vessel may include providing a preform being formed of work hardened aluminum. The preform may have an open portion, a closed portion, and body portion. A multiple segment mold may be closed around the preform. The multiple segment mold may include at least one projecting portion operative to partially deform the preform while closing the mold. The preform may be blow molded by causing a step-like change in pressure within the preform to cause the preform to take a shape defined by the mold when the mold is in the closed position. The molded preform may be removed from the mold.
