Computer modeling of bulb forming in a ribbon process is performed using the finite element method. In the language of fluid mechanics, the transient-free surface problem, further complicated by strong thermallflow coupling and material nonlinearity, is solved for flow driven by inner pressure and gravity. Effects of various process parameters on blank formation are investigated with particular attention to the development of the wall thickness non-uniformities. Agreement between the computational results and experimental data is shown to be very good. The newly developed tool has been implemented in the factory with a staggering effect on productivity and product quality.
