Scholling that is actually casting. From what I have read metal powders are blended and mixed with a polymer and additives.
Then they are processed on conventional injection molding machines used for thermoplastic materials into so-called green parts. The polymers serve as a binder that allows the metal powders to be injection-molded. The binder is removed from the green parts in a continuous process under a highly defined and controlled temperature-time profile. Subsequently, the parts are sintered to their final density.
After they are finished, there is little machining to do.
