The capital goods required for textile industry, fertilizer plants, power projects, cement, steel and petro-chemical plants, mining, construction and agricultural machineries such as equipment for irrigation projects, diesel engines, pumps, tractors, transport vehicle etc are being produced indigenously, and are included in heavy equipment and machinery industry. There are some light mechanical engineering industries which are producing wrist watches, razor blades, sewing machines and bicycles etc.

Engineering industries cover a wide range of industries and contribute substantially to the manufacturing of industrial machines, machine tools, transport, transmission and telecommunication equipments, building and construction, public health and sanitation and modern sophisticated goods. These industries need a large number of components which they do not produce themselves.

Therefore, they have stimulated a large number of ancillary industries which depend upon the main engineering units. The products of the engineering industries cover a wide range varying from pins, screws, nuts and bolts through light and heavy machinery to ships, aircrafts, automobiles, rail coaches, air conditioners and computers, etc. Thus engineering industries are labour intensive and capital demanding and are located mainly in those areas where these major – components are available.

At present, engineering industries account for about one-third of the production capital in the organised sector, one-third of the value of output and nearly 30 per cent of the employment in the public sector. Further, these industries contribute about 10 percent of the total exports of the country.

Engineering industry has witnessed great diversification during the last three decades; machineries used in the manufacture of cotton textile, jute, sugar, cement, transport equipments, earth moving equipment, tractors, pumps all are now produced indigenously.

The Indian machine tool industry is rapidly adapting itself to advance technology. Engineering industry requires foundry grade iron alloys and special tools as raw materials and skilled labour. This industry mostly scattered in and around Jamshedpur, Durgapur, Kolkata, Nagpur, Delhi, Chennai, Bhadravati, Bangalore, Mumbai, Pune, Ahmedabad, Kanpur, Lucknow, Agra, Gurgaon and Noida.
