manufacturing

Manufacturing is the production of products for use or sale using labor and machines, tools, chemical or biological processing or formulation, and is the essence of secondary industry. The term may refer to a range of human activity from handicraft to high tech but is most commonly applied to industrial design, in which raw materials from primary industry are transformed into finished goods on a large scale. Such finished goods may be sold to other manufacturers for the production of other more complex products (such as aircraft, household appliances, furniture, sports equipment or automobiles), or distributed via the tertiary industry to end users and consumers (usually through wholesalers, who in turn sell to retailers, who then sell them to individual customers).
Manufacturing engineering or manufacturing process are the steps through which raw materials are transformed into a final product. The manufacturing process begins with the product design, and materials specification from which the product is made. These materials are then modified through manufacturing processes to become the required part.
Modern manufacturing includes all intermediate processes required in the production and integration of a product's components. Some industries, such as semiconductor and steel manufacturers use the term fabrication instead.
The manufacturing sector is closely connected with engineering and industrial design. Examples of major manufacturers in North America include General Motors Corporation, General Electric, Procter & Gamble, General Dynamics, Boeing, Pfizer Precision Castparts And FCA. Examples in Europe include Volkswagen Group, Siemens, FCA and Michelin. Examples in Asia include Toyota, Yamaha, Panasonic, LG, Samsung and Tata Motors.
