3:59 "casting is a very finely balanced thermodynamic process done under high pressure - molten aluminum is pressed into a die mold at high speed and that liquid metal has to fill the mold perfectly and evenly before cooling into a single strong component. The larger and more complex the mold, the further the metal needs to travel and the greater the chance that something will go wrong."
Ricardo Ferrario saw the writing on the wall that the transition to electric vehicles would obviate the casting of engine blocks; he literally had a dream:
3:19 - he wanted to make the most powerful, efficient, and sustainable casting machine ever built, but he also wanted it to look beautiful... pops of red... stylized look... 3:43 he wanted to make the Ferrari of casting machines.
4:53 the molten aluminum is purified by pumping argon gas through, then filtered at 25 micrometers, the die mold is slathered with soybean oil for easy de-molding,
5:54 the molten metal inside the mold exerts pressure to push the mold halves apart, so immense pressure is needed to push the halves together - much more pressure than was used to inject the metal. 7:08 For instance, in a smaller press, 241 tons of pressure inject the liquid metal, but 4000 tons of force hold the die halves together.
