Metal injection molding is also a thing but I haven't heard it called liquid metal. Usually its MIM.
>Liquidmetal has also notably been used for making the SIM ejector tool of some iPhone 3Gs made by Apple Inc., shipped in the US.
MIM is something else, that's right, but properties of Liquid Glass allows it to be injection molded AFAIK.
MIM process is completely different from casting Liquid Metal. MIM generally starts as a powder and heated and molded, Liquid Metal can be just "melted and molded".
I have a stainless steel razor built with MIM. Has no resemblence to SanDisk Titanium's feel (which I also have).
I did my Ph.D. by developing BEM evaluators for working on metals, but glasses (as in class of materials) were not in my domain, so I'm thick as a brick on that part of the materials science.
Edit: BEM methods is as fun as USB buses and PSU units.
