The document discusses foundries and how new technologies have impacted them. Foundries involve machinery, manpower, and advanced technologies to carry out metal casting, furnace work, molding, and other production processes. The introduction of new techniques and technologies into foundries and factories starting in 1900 led to benefits like less work, less time, lower costs, reduced manpower needs, more ways to earn money, and improved productivity. However, between 1901-1999 there was a lack of advanced technologies, resulting in losses such as more work, greater manpower requirements, higher costs, more space needed for outdated factories, and lower productivity.

4. Foundry
 Foundry consist machinery , man power , advance
technology etc.
 Foundry contain mainly metal casting , furnace
,molding and other process[production]
 After all of that,
 New technologies and techniques enter in foundry
and factories.

5. Benifits
 When different techniques and technologies entered

in factory then lot of benefits are creates for all of us.
1.less work
2.less time
3.less money [low cost machine]
4.less man power
5.more ways of earning
6.good productivity

6. loss
 We need more new and more advance but 1901-1999

there is no more advance technologies and techniques.
So there are lot of losses.
1.more work
2.lot of man power
3.lot of money for buy machines
4.lot of space occupy old type factory
5.only one way of earning money
6.not so good productivity

7. Advance technologies
