Sand Casting The Most Extensive Process
Sand castings are made of clay bonded sand for the production of cast materials, is a long history of the process, but also the most widely used process.
The Characteristics of Sand Casting and Its Application
Sand casting has a long history, can be traced back thousands of years ago; on the scope of its application, you can say no one around the world.
Sand casting It is noteworthy that, in a variety of chemical bonding sand vigorous development today, clay wet sand is still the most important modeling materials, its wide range of applications, consumption of large, any other molding materials can not be compared with of. According to reports, the US steel castings, with clay wet sand manufacturing accounted for more than 80%; Japanese steel castings, with clay wet sand manufacturing accounted for more than 73%.
Sand casting Adapt to the modeling conditions of the strong, but also a major feature of clay wet sand. 1890 shock pressure molding machine come out, long-term used for hand-shaped conditions of the clay wet sand, for the machine shape is extremely successful, and after the modeling operations mechanization, automation laid the foundation. Modern high-pressure modeling, injection molding, gas Chong modeling, static pressure modeling and non-shock vacuum pressure molding and other new technology, are also based on the use of clay wet sand as a prerequisite.
Sand casting The implementation of various new technologies, so that the wet clay sand in the status of casting production is more important, but also to the clay wet sand face many new problems, prompting us on the clay wet sand research continues to strengthen, deepening understanding.
Nowadays, with the rapid development of science and technology, the demand for castings in various industrial sectors is increasing. At the same time, the requirements of casting quality are getting higher and higher. The productivity of modern foundries and modeling equipment has been increased to an unprecedented level. If the performance of the molding sand can not be adequately adapted to the specific production conditions or can not be effectively controlled, it will not be long before the foundry can be buried in the waste in.
