Working off the success of the gigapresses it used to make the Model Y, Tesla could push the technology even further to make the entire underbody of the Model 2 out of a single part, saving time and money. But there are still some kinks to iron out
) out of a single piece, saving both time and money during the manufacturing process. By comparison, the equivalent portion of a conventional car is made up of about 400 pieces.
However, Tesla has not yet made a final decision on whether to commit to the decision because of how difficult these tools are to get right. The larger the press, the more it costs to make, and while a new car is being designed, a company can go through several iterations of tooling as it irons out things as small as squeaks and rattles, or as big as structural flaws.Tesla believes it has found some of the solutions to these problems.
By using sand in the molds, Tesla has been working on large presses that can make underbodies with hollow sections. It has had to overcome obstacles to achieve that, though. For one, the alloys typically used in auto manufacturing don’t cool right when they have a big block of sand in them, changing the thermal properties of a mold.
Again, the automaker turned to its suppliers to come up with new metal recipes that can cool with the 3D printed sand in them. However, it still cannot find a way to use this technique with its 16,000-ton“Tesla could still choose high-pressure for productivity, or they could choose slow alloy injection for quality and versatility,” one of the sources told Reuters. “It’s still a coin toss at this point.
However it chooses to proceed, the new models will no doubt be dissected by other automakers to see if the results are works of art like the Model Y, and whether such an investment will pay off for them.
