A Chinese Company Just ‘Gigacast’ An Entire Underbody
Chinese automaker Chery Auto has cast an entire underbody using a 13,000-ton dual-injection press. Huge castings are amazing when they’re warranted. Subframes, suspension arms, drive motor housings, hubs, dashboard support structures, seat frames, if it bolts on, you name it. However, casting an entire underbody in one go seems like a process with downsides for consumers. A car is the second-most expensive thing you’ll buy in your life, so let’s keep them repairable.
It may be that significant R&D was required to get the die design to flow the metal just right without porosity or early solidification. Chery may not want anyone to see flow patterns in the casting that might teach them something. Alternatively, maybe they’re just hiding the geometry of the final part due to its relevance to their upcoming models. Or maybe these castings are full of defects and they’re hiding the evidence? That’s a long shot, though. Why would they boast if they can’t make the castings work?
