WEBFI-TECH-#17 Tesla’s Gigacastings, Micron Precision, and Unique Alloy

This videos gets into the nuts and bolts of Tesla’s Gigacastings, Tesla Giga Press, Micron Precision, and Unique Alloy, which requires no heat treat, coatings, and doesn’t warp/potato chip.

This is part seventeen of the Lithium Mine to Battery Line Series to break down and understand what was unveiled at Tesla Battery Day. We’ll start with some background on the Giga Press, move on to the benefits and then look at the challenges of casting at this scale.

    These gigacasted car parts will really make cars very difficult to repair. One hit you have to get a new car.

    Great video!! Can anyone share the link of Munro video that appears in minute 16:15?

  • Ian Burnett on October 17, 2021

    And exactly how will crash damage be repaired you numpty.

  • Sripal vlogs on October 20, 2021

    But one crack in casting with total the car. Accident repairs will be expensive and castings cannot be repaired easily

    Thanks for the reference to our 7-year program to increase use of magnesium in automotive applications, (Magnesium Front End R&D -MFERD) sponsored not only by the DOE but also equally by the US Big -3 auto makers, the Natural Resources Canada and the Chinese Ministry of Science.

    Why not carbon fibre ???

  • Greg Ramsey on October 24, 2021

    Micron precision lol

  • Bubba Fatas on October 26, 2021

    No one ever mentions that these large casting renders the car irreparable in even some minor to moderate accidents!

  • George Ginsburg on October 27, 2021

    Thank you for the technical detail. It’s amazing you were able to collect some of those facts.

  • Road Mound on October 29, 2021

    Thank you… What a lecture on all these new manufacturing technologies that TESLA has implemented in the automotive world… Elon is winning the automotive race with innovation even in automotive manufacturing … Legacy automakers are getting way behind and without Unions… TESLA will be the best for awhile.

    @TheLimitingFactor maybe I'm ruining the fun but why is everything Tesla 'giga' when gigaberlin will only be 0.5 'mega' cars per year and giga press is only 'kilo' psi.
    Should we just shrink all our units 1,000,000x to make them giga lol?

  • shawn emmerson on October 31, 2021

    Where do you get this info from. I'm at a gm plant and the 1000 robot welders is laughable. Even in older models there is nowhere close to 1000 welders in the vehicle for a 2 model plant. You don't use a single mold because if any issue with the original cast happens and it happens you can't make up plus minus just by shifting it over. It's an entire back end. Just sheets welded together you can realign later. As for quality you got to xray or ultrasonic a cast to find cracks if a bad weld happens for us we pull every car nessary to fix. Casts are just scrap if cracks happen in some points

  • shawn emmerson on October 31, 2021

    Mass manufacturing doesn't have the same standard as a rolls Royce that's why they cost what they do. Hand built mass produced wont happen it about controlling your plus minus on any part you can to keep it inside a body tolerance. You cast 9r weld it has to fit inside that tolerence. Things can move for welding a single cast that's your part it fits the tolerance or it doesn't alot less flexibility in the procedure

  • shawn emmerson on October 31, 2021

    A micron for auto parts is ridiculous try 20 to 30 thousands for any engine or body part. A micron really every piece of every car is made by a machinist who can hold a micron persison. Not even rolls can say that

  • Len Gould on November 2, 2021

    When does Tesla buy a Tweel mfg. line?

  • Tim Scroggins on November 6, 2021

    Nice job pro

  • Rock On on November 7, 2021

    Have you done the math on how many giga presses it will take to meet Tesla's production targets? With 2 presses per vehicle and 250k parts per press, that a boat load or two of machines. Also did you ever hear a cost estimate for one of the machines?

  • Denijal Denic on November 12, 2021

    It will be interesting in case of accident. How will they patch up car ? Will they just replace the whole casting 🤔

  • Alex Tigre on December 4, 2021

    IDRA? Hum… More like HYDRA. World domination one electric car at the time. Cut one chassis, two more will come.

    Now if they would make hybrids this way, they would have a path to the future. Batteries are and will be the most limiting hurdle to practicality.

  • GeoFry3 on January 8, 2022

    Excellent video. I never had an interest in manufacturing as a job, but definitely enjoyed the materials and manufacturing courses.

  • Rich on January 8, 2022

    Its amazing to think about whats going on in ALL the engineering sectors.Tesla is writing the curriculum and new engineering students are judging there position in there field of science on whether they're good enough to work for Elon Musk.
    Exciting world .

  • Adrian Moisă on January 9, 2022

    Wow! I'm blown away by the quality of presentation! Exceptional work!

  • Michael Blosser on January 11, 2022

    I think this channel deserves as much support as possible. I'm not in a position to do so because while this fella was in class studying math and science I was out behind the sports shack smokin dope and snortin meth. Hence at 66 I'm still working for minimum wage!
