Abstract: An apparatus and a method for producing a one-part vehicle wheel are provided, in which a substantially disk-shaped, undercut-free preform is cast. Immediately after casting the preform is conveyed to a flow-forming machine, whilst maintaining a residual heat and is fixed therein. The circumferential area of the fixed preform is split and by subsequent spinning and flow-forming is constructed as an intermediate form with a rim, which already substantially has the wall thickness of the rim of the finished vehicle wheel. The intermediate form is cooled, sized and undergoes a final end-working.
