![]() Manufacturing comprises three processes: assembly, extraction, and alteration. Assembly is the process by which parts are combined to make a product. An example is a car, when many parts — doors, wheels, and windows, for example — are combined to make one product. Extraction is a process during which something is removed from a raw material. An example would be gasoline, which is removed from crude oil. Finally, alteration is when you take a raw material and remodel it so that it becomes something else. A good example of alteration is sawing trees, which would then be used for wood.
The first modern-type factories appeared during the middle of the 18th century in England, during the Industrial Revolution. These earliest factories were mostly used to manufacture textiles. Slowly, but surely, machines began to replace manual labor. One of the first and most well-known machines, the cotton gin, was invented by Eli Whitney in 1793, and was designed to mechanically remove cotton fibers from the seed in a faster, more effective way. The steam engine, developed by Thomas Newcomen, James Watt, and Richard Trevithick in England, and by Oliver Evans in America, allowed the building of factories away from water sources, which had previously been needed to power machines.
When the development of reliable railroads meant that materials could be brought from near and far, this created a need for more industrial labor. After World War II, when inflation was high and the amount of factory workers had grown, organized unions that protected the rights of factory workers began to spring up. These unions allowed factory workers to negotiate for better working conditions and better wages. Manufactured products are generally broken up into two categories: durable goods and non-durable goods. Durable goods comprise goods that are designed to last for a long period of time, such as cars and appliances, while non-durable goods comprise items with a relatively short lifespan, such as clothing, food, and paper. In the Regional Directory, manufacturer listings are grouped into Mfg categories.
