Metal processing refers to the series of techniques used to manipulate and shape metals into desired forms and properties. This includes processes such as casting, where molten metal is poured into molds, and forging, which involves shaping metal using compressive forces. Other methods include machining, where material is removed from a solid block to create precise shapes, and welding, which joins metal pieces together. The goal of metal processing is to produce components that meet specific requirements for strength, durability, and functionality. Industries such as automotive, aerospace, and construction rely heavily on these processes to create everything from car parts to structural beams.
