AI Technical Summary

⚠Technical Problem

In the existing technology, the tailgate outer panel with the taillight design has a deep stamping depth and complex shape, which makes it difficult to meet the forming requirements, resulting in product quality problems such as cracking, deformation and insufficient dimensional accuracy, affecting the production yield.

⚗Method used

The taillight mounting plate and the tailgate body are manufactured separately, using independent molds and molding processes. To address the unique shape and structural requirements of the taillight mounting plate, more suitable molding processes and parameters are adopted to form an integrated structure.

🎯Benefits of technology

The molding quality and precision of the taillight mounting plate were improved, the scrap rate was reduced, the mold development cost and cycle were lowered, the product quality and appearance quality of the vehicle were enhanced, and a continuous taillight design was achieved.
