is using big aluminum die casts to make a large rear underbody section of the vehicle, measuring 1.4 meters long and 1.6 meters wide. This alone has allowed it to reduce the number of welding points by almost 800.
Furthermore, it makes the vehicle lighter, increases the structural stiffness, and should reduce defects, Zeekr manufacturing technology chief Jiang Kehong revealed.Tesla started using aluminum die-casting machines for the Model Y in late 2020. The machine it uses are manufactured by Italy’s Idra Group and use shots of molten aluminum that are injected into a cold-chamber casting mold. Once the piece has solidified, it is removed and robots clean the chamber for the next cast.
