Tesla has combined a series of innovations to make a technological breakthrough that could transform the way it makes electric vehicles.
The company pioneered the use of huge presses with 6,000 to 9,000 tons of clamping pressure to mold the front and rear structures of its Model Y in a "gigacasting" process.
Tesla is closing in on an innovation that would allow it to die cast nearly all the complex underbody of an EV in one piece.
The subframes in a car underbody are typically hollow to save weight and improve crashworthiness.
At the moment, they are made by stamping and welding multiple parts together leaving a void in the middle.
To cast subframes with hollows, Tesla plans to place solid sand cores printed by the binder jets within the overall mold.
