A method for chipless production of a rotationally symmetrical body from a circular sheet metal blank shapes the circular sheet metal blank into a pot-shaped body by pressing or pressure rolling around an inner mandrel, and a hub-shaped projection protruding outward from the base of the pot-shaped body is molded on by pressing around a central projection. The circular sheet metal blank is clamped only in the radial inner region of the blank in the axial direction between the inner mandrel and at least one projection during the shaping process.

A method for producing a container having an upper part, a lower part and a receiving element such as an electronics module includes the following steps: the lower part is created from a first starting material in a first processing region of a processing device; the upper part is created from a second starting material in a second processing region of the processing device; the receiving element is fed into the first processing region of the processing device; the lower part receives the receiving element in the first processing region of the processing device; the upper part is fed from the second processing region into the first processing region of the processing device; and there the upper part and the lower part are joined together to form the container.

A method for forming heatsink tube includes cutting a base sheet plate into a first molded frame and a second molded frame, applying a flux on an inner face of the first molded frame and the second molded frame, mounting the first molded frame on a heatsink fin module, and mounting the second molded frame on the first molded frame, to assemble the first molded frame, the heatsink fin module, and the second molded frame, and to form a heatsink tube. The first molded frame has a first end faceplate and two first connecting portions. The second molded frame has a second end faceplate and two second connecting portions. Each of the two first connecting portions is formed with a first abutting section, and each of the two second connecting portions is formed with a second abutting section.

A method for chipless production of a rotationally symmetrical body from a circular sheet metal blank shapes the circular sheet metal blank into a pot-shaped body by pressing or pressure rolling around an inner mandrel, and a hub-shaped projection protruding outward from the base of the pot-shaped body is molded on by pressing around a central projection. The circular sheet metal blank is clamped only in the radial inner region of the blank in the axial direction between the inner mandrel and at least one projection during the shaping process.
