Abstract: The present disclosure provides an improved process for manufacturing vehicle 5 wheel rims with controlled rim width and enhanced dimensional precision. The process starts by coiling a metal strip and welding the ends to form a continuous hoop, followed by trimming, re-rounding, and sanding for a smooth profile. Flaring and forming operations using hydraulic presses shape the flange, while well base spinning reduces thickness and volumetrically increases width. 10 Sequential roll forming operations include an initial step to partially shape the tyre seat and gutter, followed by a final roll forming step for precise dimensioning. Precision machining of the gutter end controls rim width variation within -0.5mm to +0.5mm. The process concludes with diameter adjustment, valve slot piercing, and marking for traceability. This method achieves material savings of up to 2.5 15 kg, reduces production costs, and enhances tire fitment quality, providing substantial advantages over conventional rim manufacturing methods.
