This invention relates to a thermoforming process for a rear longitudinal beam. This process designs the sidewall surface corresponding to the feature surface at the overlap of the automotive sheet metal rear longitudinal beam and sill beam as an arc shape. This effectively controls the material flow direction, reduces forming friction, and improves wrinkling and cracking phenomena caused by uneven material feeding at the overlap surface. Furthermore, it does not affect the feature surface shape of the rear longitudinal beam, thus achieving a significant improvement in the quality of the corresponding part. Without altering the feature surface shape of the rear longitudinal beam, the sheet metal thickness is reduced, meeting the requirements for automotive lightweighting.
