RE:RE:RE:RE:RE:New on exro’s website! It indicates they are looking for companies to mass produce parts and pieces for the EXRO products and they are rapidly transitioning from development to sales. It's an EXCELLENT development.
PCB's are printed circuit boards.
cast parts are highly specialized as you have to make the molds and then melt aluminum and fill the molds. Very expensive to set this up and the supply chain takes time to set up so it's easier faster and cheaper to hire this out.
For example Boeing aircraft makes very few if any parts anymore. They have suppliers make them all and all Boeing does is assemble the planes with parts made literally all over the world and shipped to Everett or wherever else they are making the plane.
looks like Exro is setting up to do the same as Boeing. (Brilliant approach) Exro doesn't have the time to set up in house manufacturing and it would consume too many resources both in time and $$
