　　Aluminum alloy die-casting plants use a large amount of energy and raw materials in the production of castings. Casting is an energy and resource intensive industry, and a large amount of waste is generated during the production process. The most serious environmental pollution caused by casting enterprises in the production process is air pollution and solid waste.

　　The air pollution in foundries is characterized by low concentration and large gas volume. According to a pollution report by the US Environmental Protection Agency, among the 188 known air pollutants, more than 40 types of casting waste gas are produced, posing a threat to environmental protection and detrimental to human health development. Effective measures must be taken to control pollutants. Firstly, replace the fuel melting furnace with an electric or gas furnace that causes less air pollution, and choose a flux that causes less air pollution. Secondly, install an oil filter above the die-casting parts to filter out harmful gases and reduce pollution. During the production process, methods such as activated carbon adsorption, isoion method, chemical dissolution method, and biodegradation method can also be used to treat waste gas.

　　However, the exhaust gas treatment in aluminum alloy die-casting plants is still only the end of the line treatment method. To fundamentally remove it, it is necessary to stop it at the source, adhere to the principle of environmental friendliness, comply with national regulations in the production process, and reduce environmental pollution.
