Module 03.2.1 Production and final objects - metal

sheet forming for the forming of sheet metal, two parts may be used, one called the upper die "Ziehglocke", performs the streching operation, while the under die "Ziehstempel" and the lifter "Niederhalter" securely clamps the edges of the workpiece to prevent wrinkles. In serial production, such as automobile body parts, the workpiece may pass through several stages using different tools or an progressive die to obtain the final form. There will usually be a shearing operation after the main forming is done and then additional crimping or rolling operations to ensure that all sharp edges are hidden and to add rigidity to the panel.

Finishing brass polished, steel water-based painting white, copper polished, copper enamel transparent "flieder", steel water-based painting red.
