Casting is a metal forming process in which molten metal is poured into a mold and, after cooling and solidification, a casting with a predetermined shape, size, and performance is obtained. The casting process usually includes steps such as melting, pouring, cleaning, and inspection.
The advantages of the casting process are that it can produce castings with complex shapes, accurate dimensions, and uniform internal structure, with high production efficiency and relatively low cost. The casting process is widely used in industries such as machinery, transportation, construction, and metallurgy.
Casting technology has a history of about 6000 years. In China, casting can be traced back to 6000 years ago. Between 1700 BC and 1000 BC, China entered the heyday of bronze casting, and the technology had reached a fairly high level. With the development of science and technology, the casting process has also been continuously improved. Modern casting technology has adopted many new technologies and materials, such as computer simulation, rapid prototyping technology, new refractory materials, etc., greatly improving the quality and production efficiency of casting.
In addition, the increasing awareness of environmental protection has also prompted the casting industry to continuously improve its production processes to reduce pollution to the environment. For example, using clean energy to replace traditional fuels and using non-polluting or low-polluting materials.
