Industrial ways of turning molten or solid metal into shapes, including continuous casting, which solidifies molten metal into billets and slabs, extrusion, which pushes material through a die to a fixed profile, spray forming, which builds near net shape parts from sprayed semi solid droplets, and directional solidification, which controls how a casting freezes. An invention belongs here when the cited article describes it as a casting or forming process.
