A factory, also known as a manufacturing plant, is a type of large industrial building used to produce goods. Most factories have production lines made up of large machines or equipment. In modern world history, it generally refers to capitalist machine production, that is, capitalist industrial sites that use mechanized labor instead of manual labor. In the 18th and 19th centuries, after the industrial revolution, machines were widely used in production, which laid a solid material and technical foundation for the capitalist mode of production. The capitalist economy finally defeated the feudal economy and the petty commodity economy by virtue of large-scale machine production, and established its dominant position. Hyundai's factories are also called "manufacturing plants" and "production enterprises".
