1 thought on “Tesla integrated die -casting, the traditional car company crow is silent?”

  1. I have to admit that Tesla is a star car company with its own traffic, and every move will be interpreted as "subverting tradition" and "challenge the future". Musk's business is indispensable. Of course, Tesla's genetic talent in software is indeed unique.
    So when this time, after the Tesla Shanghai Super Factory announced that large die -casting machines were put into mass production, many people were interpreted as "Tesla's Dragon Slayer again."
    Mas may stem from Musk's own evaluation of the integrated die casting of the Feli Mont plant: "This is the largest die -casting machine in the world, which can make the back of the body formed ..."
    So so In the hearts of the people who eat melon, as long as the car is divided into the front and rear parts, the rear one is formed as a kind of powerful technology. And there are also many media propaganda manuscripts, one -sided advantage of one -sided die -casting, such as "making cars like toys."
    In fact, the integrated die casting is not so subverted, and it is not so beautiful.
    In fact, integrated parts can be regarded as part of the rear plate assembly. The specific location is below the rear seat, which is under the buttocks of the rear passenger.

    What is its role. According to the literal meaning, the floor floor is used to accommodate and place it, not the main part of the structural security. When a building collapses, they will say that the ground is not firm. No one will say that the floor is not strong enough?
    So Tesla's only purpose of using integrated die casting on this part is to reduce costs from three aspects.
    The comparison, we look at how traditional car companies (or car companies except Tesla) do.

    is a plate with different strengths, cold pipes, boxes and other parts, and then welded. Therefore, the total number of parts of this piece will be as many as hundreds of hundreds.
    For this point, Tesla expressed very clearly: his own integrated die -casting technology can reduce the original 70 parts to 2.
    Is hearing this, if you have dealt with the production line, you can understand the economic value of it, as Tesla announced:
    . The pouring of 2 parts is only 90 seconds, 2 sets of molds, 2 sets of molds Essence The 70 parts of ordinary car companies are stamping welding for more than 2 hours, which is of great cost value for equipment, venues, artificial, production festivals, inspection, and logistics required in upstream and downstream production.
    But if the benefits are allocated by one, traditional cars are looking at the cost space of more than 20%, and the pot selling iron must be designed and technical.
    First of all, Tesla's 90S I think is reasonable, but the 70 parts of the "traditional car companies" are rushing stamping welding. For tailoring and stamping, it adds up to about 1 second for a simple type. Welding is welded. The rear floor assembly is mainly welded, without too much welding seam. Of course, if it is transferred from each part to the transfer belt and enters the next process, it may indeed be up to 2 hours.
    above is not the advantage of refuting Tesla. It is irrefutable that the time required for 2 parts of die -casting welding for parts is absolutely less than 70 parts of the processing welding process, but it is not so exaggerated. Smart eggs choose to update equipment and processes.
    It, although the die -casting is integrated, it sounds more intensive. In fact, the process control is more difficult, far less than the cold pressure to mature.
    In a little joke, the picture above is gravity pouring, while die casting has the main process of jet pressure. However, the picture above can illustrate a certain problem. The details of the casting itself are far worse than the processing of parts-assembled-unless it is unless the shape is not complicated and only considers the intensity, such as the engine cylinder, the steering steering The festivals are on the big block.

    Since the aluminum is melted and sprayed and compressed, it is necessary to consider the factors that cause deformation caused by thermal expansion and contraction. And unreasonable temperature changes may also affect the intensity consistency.
    above is the reason why traditional car companies do not need to die -casting, so mature upstream -steel mills, so mature crafts — stamping welding, can also make quality and consistency firmly controlled in the hands of quality engineers. inside. To change, the entire industry must have new supporting and groping processes, which cannot be drawn.
    Therefore, Tesla’s rear flooring is not enough to stun the traditional car companies. Many of them have evaluated the pros and cons of this process, and finally chose to give up (or use it in the small small small (or use it in the small small. The size or special parts, not such a large and complicated assembly)
    but the die casting itself has an advantage that cannot be ignored, and it is also the only driving force for Tesla to do this -cost. If it can be replaced, the two points squeezed out of the teeth are both younger brothers. The larger and more complicated assemblies, the greater the cost income, the greater the cost, at least two digits start.

    and the income income will be enlarged infinitely in the production of electric vehicle production. In the end, Tesla's goal must be to press a front, a parking space, and welded on the floor. On the battery.

    think about it, changing a set of molds and pressing a car three times.
    of course, at the current level of geographical technology, Tesla also applied integrated die -casting parts in the private parts of Model Y, which is a kind of attempt and experience. For traditional car companies, there is no motivation to make too much change. Unless the core interests are challenged, for example, everyone is a B -class car, and Tesla's cost is half of you.
    The purpose of discussing technology, Tesla's new technology may not be too great in the current advantage, but it is likely to affect the direction of the industry. This is the power of powerful catfish.
