The die casting process involves the use of a furnace, metal, die casting machine, and die.
The metal, typically a non-ferrous alloy such as aluminium or zinc, is melted in the furnace and then injected into the dies in the die casting machine. After the molten metal is injected into the dies, it rapidly cools and solidifies into the final part, called the casting parts.
The castings that are created in this process can vary greatly in size and weight, ranging from a couple of ounces to 100 pounds. One common application of die-cast parts are housings - thin-walled enclosures, often requiring many ribs and bosses on the interior.
Metal housings for a variety of appliances and equipment are often die cast.
Several automobile components are also manufactured using die casting, including pistons, cylinder heads, and engine blocks. Most home appliances also need lightweight and r aluminum die castingheat dissipation . Other common die cast parts include propellers, gears, bushings, pumps, and valves.

On October 28, an 100,000 cubic metre crude oil storage tank under construction at the PetroChina Xinjiang Dushanzi Petrochemical Company Branch exploded during anti-corrosion operations, resulting in the death of 13 workers and a total of 6 injured in a collective enterprise in the contracted project in Anhui Province. . This is a rare accident in key construction projects. On October 23, the Yangquan Coal Industry Group of Shanxi Province built a project with an annual output of 50,000 tons of caustic soda and 50,000 tons of polyvinyl chloride. During the trial production, a hydrogen chloride leak occurred, causing hundreds of residents to evacuate. According to the investigation, there have been five leaks in this project. In response to the above two incidents, State Council Vice Premier Zeng Peiyan and State Councilor Hua Jianmin made important instructions, emphasizing that “the construction progress must be subject to quality and safety requirements†and “strengthen the safety management work of the projects under construction.â€
According to industry sources, the current tendering and bidding market for chemical projects is very confusing. The outstanding issues are bids and tenders, and mutual bargaining. Some petrochemical construction companies “patched†their own brands to local or private construction teams with no professional background. These teams squeeze out professional construction teams at a low price. As a result, major safety hazards are posed to flammable and explosive chemical projects.
Wang Xianzheng, deputy director of the State Administration of Work Safety, emphasized at the video conference that chemical construction projects are especially key projects. The construction team must not only have statutory qualifications, but also have corresponding technical strength, safety management experience, quality and safety reputation, and be qualified after bidding. . It is necessary to sign a standardized contract, clearly defining the rights and obligations of both parties in safety production. The contracting party must fulfill its safety responsibilities and should not take it lightly and carefully. It is necessary to select competent and competent intermediary agencies to undertake project supervision through bidding and tendering, not only to supervise the quality but also to supervise safety.
Wang Xianzheng also reminded that coal mining companies are now investing in the development of coal chemical industry, and many chemical construction projects are currently under construction. In the next two years, the contradictions in this area will gradually appear and we must take preventive measures. Chemical projects must have a market, technology, and security.
At present, there are loopholes in the establishment, contracting, construction, supervision, commissioning and quality and safety management of hazardous chemical construction projects. Vigorously strengthening the safety management of projects under construction in the chemical industry has attracted the attention of the relevant state departments. This is the message from the video conference held on November 6th by the State Administration of Work Safety regarding two major chemical construction projects in recent days.
