Rear Door Frame

Challenges & Special Features

This cast aluminum rear door frame exceeds the usual dimensions of similar components for other vehicles and prior generations. It is not only larger, but also very thin-walled with a thickness of only 3 millimeters. Furthermore, the casting is in line with the unique design aspects of the vehicle's rear design: beyond the large dimensions, the large continuous tail light of the vehicle needs to be taken into account for the mold design. In addition, a special focus is on the surface quality.
