Materials processing, the series of operations that transforms industrial materials from a raw-material state into finished parts or products. The cycle of manufacturing processes that converts materials into parts and products starts immediately after the raw materials are either extracted from minerals or produced from basic chemicals or natural substances. Metallic raw materials are usually produced in two steps. The processes used for the manufacture of a desired product generally provide two major functions: the formation or alteration of materials. The formation of parts or products is usually achieved by molding, casting or the application of pressure. The physical state or composition of commodities and products can be altered by a number of different means including chemical, mechanical and thermal operations.
