Sand casting the ability to adapt to modeling conditions is extremely strong and is also a major feature of clay wet sand. In 1890, the vibrating molding machine was introduced. The clay wet sand, which has been used for manual molding conditions for a long time, was extremely successful for machine modeling, and laid the foundation for the mechanization and automation of the molding operation. Modern high-pressure molding, injection molding, gas-punching, static-pressure molding, and non-shock-pressure vacuum molding are all based on the premise of using clay wet sand.
Nowadays, with the rapid development of science and technology, the demand for castings in various industrial sectors is growing, and at the same time, the requirements for casting quality are getting higher and higher. In modern foundries, the productivity of styling equipment has increased to unprecedented levels. If the performance of molding sand can not be fully adapted to specific production conditions, or it can not effectively control its stability, it is not necessary to bury the foundry in waste.
