The term manufacturing refers to the processing of raw materials or parts into finished goods through the use of tools, human labor, machinery, and chemical processing.

Manufacturing allows businesses to sell finished products at a higher cost than the value of the raw materials used. Large-scale manufacturing allows for goods to be mass-produced using assembly line processes and advanced technologies as core assets. Efficient manufacturing techniques enable manufacturers to take advantage of economies of scale, producing more units at a lower cost. Source: Investopedia.com
