A variety of pollution is resulted from:

1.Extensive production, casting quality without guarantee

Extensive development generally comes into the problems of harsh production environment, poor overall quality, low production efficiency, poor technology and economic efficiency and other issues. 

2.A serious lack of pollution control system

The environmental investment of the casting industry in developed countries accounts for 20% - 30% of investment in foundry equipment. The backward facilities on the environment caused by pollution is very serious in some areas.

3.Direct emission of exhaust gas in the production process

There are many kinds of links that cause exhaust emissions. Many manufacturers have different reasons: manufacturers do not install exhaust gas treatment facilities, such as electric frequency furnaces without exhaust gas treatment facilities, cupola furnaces without exhaust gas treatment facilities, and so on.

4.Uncontrolled dust emissions

Dust emissions are mainly caused by the open-air work and some substandard operation of environmental facilities.
