A variety of pollutions are 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.
 

1.Adopt new technologies and scientific casting process to improve casting quality

Green power is from science and technology, intensive "green casting" also can not do without the support of new technologies. CHAENG regards the principle of "implementing technological transformation and upgrading" as the eternal theme, eliminates outdated equipment and processes, upgrades the technological content of products and built their own unique casting process.
 

2.Eliminate the outdated equipment, to create new model of intensive "green casting" 

The realization of "green casting" not only needs to change the technology, but also the production environment and production equipment. CHAENG in both areas has been holding the firm attitude to ensure environmental production in the production process, to achieve "green casting."
 

3.Focus on worker health management

It is the long-term purpose of CHAENG to provide customers with high-quality steel castings. However, to provide staff with advanced casting environment is the the biggest principle of CHAENG to build "humanistic business". CHAENG actively applies for green building construction qualification, safety and health production qualifications, to ensure better customer service.
