Metal casting technology

1. Overview of metal casting technology

　　Metal casting technology is based on metal, through the casting process, in the mold will be melted metal, poured into the model and rapid cooling and molding methods. Metal casting in addition to commonly used casting methods, such as sand casting, precision casting, vacuum casting, die casting, low-pressure casting and high-pressure casting and several other major branches, especially in the field of computer simulation, process optimization, mold manufacturing and materials processing and other areas of technology applications have been widely promoted.

　　Second, the application of metal casting process

　　1, the automobile industry

　　Metal casting technology is one of the most widely used processes in the automotive industry. Its main application is the manufacture of engine block, cylinder head, crankshaft, connecting rod and other key components. Compared with other processes, metal casting is inexpensive, can produce large quantities of the same parts, and manufactured parts also have high strength, stiffness and corrosion resistance and other advantages.

　　2, aerospace

　　Metal casting technology in the aerospace field is widely used, can produce a variety of complex shapes of parts and components. For example, metal casting can be used to manufacture aircraft engines and landing gear and other components. These components usually need high strength, high hardness, and need to have a high degree of accuracy and precision.

　　3, medical equipment

　　Metal casting technology is also widely used in the field of medical equipment manufacturing and artificial limb manufacturing. For example, prostheses and bone implants can be produced by metal casting technology, and through subsequent processing and treatment, can make it have the required biocompatibility.

　　4, other fields

　　Metal casting technology is also widely used in many other fields. For example, it can be used in the manufacture of faucets and spouts, the manufacture of beer and soda cans and other everyday products. In addition, metal casting technology can also be used to manufacture industrial equipment, power equipment and so on.

　　Third, the development trend of metal casting technology

　　1, digital production

　　With the development of computer technology and numerical control technology, digital technology is penetrating into all aspects of the manufacturing industry, metal casting technology also benefits from digital production. Modern digital production technology to improve production efficiency, reduce waste and human error. Digital technology for the metal casting industry provides new opportunities and challenges.

　　2, green manufacturing

　　Green manufacturing is one of the important trends in the future of manufacturing, metal casting technology is no exception. Green manufacturing emphasizes the manufacturing process to minimize pollution of the environment. How to reduce energy consumption, reduce waste water emissions, improve resource efficiency has become the casting industry needs to address the issue.

　　3, three-dimensional printing technology

　　Three-dimensional printing technology is one of the most popular manufacturing technologies in recent years. Metal casting technology through the combination of three-dimensional printing technology can expand their own applications. Three-dimensional printing technology can not only manufacture very complex parts, but also in the design and trial production to shorten the cycle time. Therefore, the development of 3D printing technology will bring new opportunities for the development of metal casting technology.
