Manufacturing is the production of goods through the use of labour, machinery, tools and biological or chemical processing or formulation. Manufacturing can either mean transforming raw materials into finished goods on a large scale, or the creation of more complex items by selling basic goods to manufacturers for the production of items such as automobiles, aircraft, or household appliances.
Raw materials are transformed into finished products through manufacturing engineering or the manufacturing process. This process begins with product design and materials selection. The materials are modified during various manufacturing processes to create the finished product.
Modern advanced manufacturing often includes several intermediate processes to create the various components for a finished item, with some manufacturers using the term fabrication. Manufacturing has close connections to the engineering and industrial process design sectors.
