Factories and things made by machines are all called industry.  Industry refers to the manufacture of raw materials by machine, which are used in the daily life of human beings. There are three types of benefits of factories.  On the one hand, they meet human needs.  The second is the addition of human comfort.  And third, things can be made easily and quickly.  Different industries work together.  Which makes things less expensive to make.  At present, the production of industrial goods is increasing exponentially.

National development 
During the partition, Pakistan got those areas.  Which were more industrially backward.  Hindus were big industrialists and capitalists.  Where factories were not established in Muslim-majority areas.  When all the raw materials were available there at cheap rates.  Yet these areas were kept away from industry.
In East Bengal, the production of Puttsun was 50% of the total world production. However, not a single Puttsun factory was set up there.  On the other hand, in West Bengal, more than a hundred Puttsun factories were operating on the Hugli River Cup.
Cotton was grown in West Punjab.  However, textile mills were established in Mumbai and Ahmedabad, at the time of independence Pakistan there were cotton, sugar and a total of seven cement factories.  Therefore, Pakistan started its industrial development on a weaker basis.
The Pakistani government realized that the country was lagging behind industrially.  Therefore, special efforts were made to establish a strong industrial system.  An industrial policy was announced in 1948, which encouraged the private sector.  In 1972, the government nationalized ten types of factories.  At the time, the government's actions created uncertainty in the private sector.  Capitalists are now reluctant to invest in industry.  The subsequent government made state-controlled factories private in the same way.  In addition, the private sector paved the way for setting up new factories and investing in them.  As investors invest in Pakistan's industrial sectors.

Industries 
Industries in Pakistan are divided into the following categories
 (1) Domestic and small scale industries
 (2) Large industries
 (3) Defense industries

Small home industries 
Small and cottage industries are very important.  Because they provide employment at the local level.  They cost less to set up.  And the administrative structure is also small.  When the focus is on small and cottage industries, human migration from the countryside to the city will be reduced.  There are so many types it's hard to say.  Small and cottage industries have a significant role to play in Pakistan.  Thousands of people work in them.  Which strengthens the country's economy.

Large industries 
In large industries, the lower factories are counted.

(1) Textile Mills:
The textile industry is the backbone of Pakistan's economy.  These factories produce the best quality fabrics.  Pakistan is self-sufficient in cotton cloth.  Millions of rupees are earned every year by selling these clothes abroad.  Special centers for textile industry are Faisalabad, Lahore and Multan (Punjab), Karachi and Hyderabad (Sindh).  Occurs in Peshawar, Dera Ismail Khan, Nowshera, Bannu, Haripur and Swat (Khyber Pakhtunkhwa) and Athal and Quetta (Balochistan).
There are more than 500 industrial factories in Pakistan.  In which only 3 factories were invented at the time of independence in 1947.

There are also woolen factories in Pakistan.  But cotton is no match for textile mills.  The main reason is that low quality in Pakistan is obtained from it.  It is used to make more wool or blankets.  Major woolen factories are located in Karachi (Sindh), Lawrencepur (Rawalpindi), Lahore, Quaidabad (Punjab), Harnai (Balochistan) and Bannu (Khyber Pakhtunkhwa).  Where blankets and woolen cloth are made from wool particles.  There are currently 70 woolen factories in Pakistan.  Lawrencepur and Karachi factories produce high quality woolen cloth.

(40 in Punjab, 32 in Sindh, 6 in Khyber Pakhtunkhwa) The production capacity of all these factories is 5 million tons.  Pakistan is not only self-sufficient in sugar but also sells it to foreign countries.  From them
Earning income.  The sugar made in Pakistan is of high quality.

(3) Cement factory:
Gypsum is used in the manufacture of cement.  Fortunately, Pakistan has large deposits of Chen stone and gypsum.  That is why so many cement factories have been set up in the public or private sector.  They are operating under the administrative regulations of Pakistan State Cement Corporation (PSCC).

Cement factories are operating in the lower areas of Pakistan.
