How do foundry technicians create these hollow internal chambers during casting without compromising structural integrity or leaving process holes on the outside? Is this done using expendable sand cores, gas-assisted injection molding, or by joining two separate pieces together??

Would love a detailed breakdown from anyone familiar with advanced wheel manufacturing.

As soon as I came home from a ride, killed the engine using the kill switch and again tried to switch it back on, I'm facing this issue. I'm planning on taking her to the service center but I want to know if anyone faced the same issue.
