Which process involves shaping materials through molding?

The process that involves shaping materials through molding is encompassed under forming and metalworking. This category includes various methods where a material is shaped into a desired form. In molding, for instance, materials, often in a liquid state, are poured into a mold and allowed to solidify into the shape of the mold. This process is widely used in manufacturing items from metals, plastics, and other materials, making it an essential aspect of production in various industries.

While rolling, forging, and extrusion are all specific shaping processes, they either don’t primarily involve molding or represent narrower techniques under the broader category of forming. Rolling typically involves reducing the thickness of materials through compressive forces, forging shapes metals through compressive forces, and extrusion drives material through a die to create shapes. Each of these processes has its unique applications but does not broadly encompass shaping through the use of molds like forming and metalworking does.
