Manufacturing engineering is the field of engineering that designs and optimizes the manufacturing process, or the steps through which raw materials are transformed into a final product. The manufacturing process begins with the product design , and materials specification .
An ancient process of steelmaking was the crucible process. In the 1850s and 1860s, the Bessemer process and the Siemens-Martin process turned steelmaking enabled industrialization. Two major commercial processes are used. Basic oxygen steelmaking uses liquid pig-iron from the blast furnace and scrap steel as the main feed materials.
Manufacturing – use of machines, tools and labor to produce goods for use or sale. Includes a range of human activity, from handicraft to high-tech , but most commonly refers to industrial production, where raw materials are transformed into finished goods on a large scale.
The Bessemer process was the first inexpensive industrial process for the mass production of steel from molten pig iron before the development of the open hearth furnace. The key principle is removal of impurities from the iron by oxidation with air being blown through the molten iron. The oxidation also raises the temperature of the iron mass ...
Mass production, also known as flow production, series production, series manufacture, or continuous production, is the production of substantial amounts of standardized products in a constant flow, including and especially on assembly lines. Together with job production and batch production, it is one of the three main production methods. [1]
Certain chemical process yield important basic materials for society, e.g., (cement, steel, aluminum, and fertilizer).However, these chemical reactions contribute to climate change by emitting carbon dioxide, a greenhouse gas, through chemical reactions, as well as through the combustion of fossil fuels to generate the high temperatures needed to reach the activation energies of the chemical ...
Process manufacturing is a branch of manufacturing that is associated with formulas and manufacturing recipes, [1] and can be contrasted with discrete manufacturing, which is concerned with discrete units, bills of materials and the assembly of components. Process manufacturing is also referred to as a 'process industry' which is defined as an ...
Plastics extrusion is a high-volume manufacturing process in which raw plastic is melted and formed into a continuous profile. Extrusion produces items such as pipe/tubing, weatherstripping, fencing, deck railings, window frames, plastic films and sheeting, thermoplastic coatings, and wire insulation.
