Classification of casting processes

Classification of Casting

Casting is a method of creating various shapes by melting metal and pouring it into molds. This ancient process has played an important role in the history of mankind. Casting is widely used in the manufacture of various metal products such as automobile parts, construction materials, tools, and so on. Casting has a wide range of applications and is able to fulfill human needs for objects of different shapes and sizes. The development of casting has had a profound impact on the progress of mankind. Through casting technology, human beings are able to produce metal products on a large scale, improve productivity and promote economic development. In addition, casting also provides mankind with more possibilities for creation and design, contributing to the development of science, technology and art. Casting not only has an important position in the industrial field, but also is an indispensable part of cultural heritage, which enriches the cultural inheritance of mankind.

Investment casting is a commonly used casting process that forms castings with the help of melting of mold materials. The process has the ability to produce complex castings with high precision and quality. However, the disadvantages of investment casting are the long production cycle and relatively high cost. Vanishing mold casting is a casting process that uses carbonization as the raw material. The process has the advantage of making fine castings and can meet the demand for high-precision castings. However, the disadvantage of vanishing mold casting is that the mold making is complicated and easily affected by the external environment. Gravity casting is the use of gravity to inject molten metal into the mold inside the casting process, it has the advantages of fast production speed, low cost, especially suitable for mass production. However, the disadvantage of gravity casting is that it is not possible to manufacture castings with complex shapes. Lost wax casting is a commonly used casting process that forms castings by dissolving a wax mold. This process has the advantage of lower production costs and is suitable for the production of small and medium-sized castings. However, the disadvantage of lost wax casting is the inability to manufacture large castings. When selecting a process, comprehensive consideration needs to be made based on specific needs to obtain the best casting results.
