Tesla has achieved a breakthrough in making Sizzling Wheels-like single-piece automotive casting a actuality, in accordance with a brand new insider report.
Lately, Tesla has closely invested in massive casting know-how to supply car our bodies in simply a few massive components reasonably than a whole bunch.
The automaker now operates a number of of the world’s largest casting machines, which it usually refers to as “Gigapress.”
CEO Elon Musk has usually referenced how he has been impressed by Sizzling Wheels toy vehicles being made in a single forged piece and hinted that he would really like Tesla vehicles to ultimately be made like that.
Nonetheless, Tesla has already pushed the boundaries of casting know-how to have the ability to produce the rear and entrance casting on Mannequin Y and had a brand new 9,000-ton press made to supply Cybertruck components.
However now a brand new report claims that Tesla has achieved “a collection of improvements to make a technological breakthrough” to “die forged practically all of the complicated underbody of an EV in a single piece.”
The report is coming from Reuters based mostly on “5 individuals accustomed to the transfer”:
The 5 individuals mentioned a single massive body – combining the entrance and rear sections with the center underbody the place the battery is housed – could possibly be utilized in Tesla’s small EV which it goals to launch with a price ticket of $25,000 by the center of the last decade.
Nonetheless, the report claims that Tesla has not but determined to make use of the brand new know-how for its next-generation car, nevertheless it may decide as quickly as this month.
Reuters claims that one of many improvements entails utilizing 3D printing and industrial sand to create the molds for casting, which may minimize the price and time it takes to make inevitable modifications to the molds:
To beat the obstacles, Tesla turned to corporations that make check molds out of commercial sand with 3D printers. Utilizing a digital design file, printers often known as binder jets deposit a liquid binding agent onto a skinny layer of sand and steadily construct a mould, layer by layer, that may die forged molten alloys.
The report mentions Tesla utilizing Desktop Metall’s ExOne machine.
One other innovation is thru materials science. The report states that Tesla confronted points with having an alloy that works each with the 3D-printing means of the mould and the efficiency and security necessities for a automotive, however the firm has made progress:
The casting specialists overcame that by formulating particular alloys, fine-tuning the molten alloy cooling course of, and likewise arising with an after-production warmth remedy, three of the sources mentioned. And as soon as Tesla is pleased with the prototype mould, it may then spend money on a closing metallic one for mass manufacturing.
Tesla has a robust materials science staff that it shares with SpaceX, and it has already designed a number of new alloys utilized by the 2 corporations.
Lastly, the report additionally mentions that Tesla hasn’t finalized plans for a brand new greater Gigapress wanted to construct these massive single unibodies.
Electrek’s Take
Tesla followers wish to criticize Reuters for publishing deceptive adverse reviews about Tesla, and there’s positively validity to the criticism, as we highlighted in a latest report.
Nonetheless, on this case, Reuters printed a really detailed report that is smart based mostly on Tesla’s plans.
We all know that Tesla has been engaged on such a know-how since earlier than the Mannequin Y got here to market, and Elon Musk briefly pushed for extra innovation within the electrical crossover’s platform earlier than backtracking a bit in favor of bringing it to market sooner.
Tesla had an attention-grabbing patent on that know-how again in 2019.
I nonetheless assume this must be taken with a grain of salt, however I wouldn’t be shocked if it seems to be true.
