Early stage
The Simuwu Rectangular "Ding" weighing 875 kilograms from the Shang Dynasty in China, the bronze zun-pan unearthed from the tomb of Zenghouyi("Zun"was regarded as wine vessel and "Pan" was regarded as water hold in Spring and Autumn Period) from the Warring States Period, and the light-transmitting mirror from the Western Han Dynasty are all typical products of ancient casting. Most of the early castings were tools in agricultural production, religion and daily life, with high artistic value. The casting process at that time developed in parallel with the pottery making process, and was greatly influenced by pottery. At that time, casting process has a parallel development with pottery process, and was greatly influenced by pottery.
Development
In 513 BC, China cast the world's earliest iron casting found in written records - the Jin State Cast Ding, weighing about 270 kilograms. Iron castings also began to be produced in Europe around the eighth century AD. The emergence of iron castings expanded the application range of castings. For example, in the 15th to 17th centuries, Germany, France and other countries successively laid many cast iron pipes to supply drinking water to the residents. After the industrial revolution in the 18th century, industries such as steam engines, textile machines and railways rose up, castings entered a new period of serving large industries, and casting technology began to develop greatly. With the rise of steam engines, textile machines and railways after the industrial revolution in the 18th century,
Modern
As we enter into the 20th century, casting has a rapid development, the one important factor is the advance of technology, which requires the better mechanical and physical properties, the other factor is the development of mechanical industry and other industries such as chemicals and instrument, provide a beneficial material condition for casting. The evolution of testing improves the quality and stability of castings, provides conditions for development of casting theory. With the invention of electron microscope, human can go into the microworld of metal, explore the metal crystallization and research the theory of metal solidification, consequently direct the casting production.
Contemporary era
Casting is one of the basic processes of the modern machinery manufacturing industry, so the development of the foundry industry represents the production strength of a country. According to statistics in 2008, China's annual output of castings is 33.5 million tons, is the largest casting country in the world. With the continuous development of foundry industry in China, the domestic foundry industry will build innovative enterprises with "four possessions", namely innovative ideas, plans, systems, and working methods. In terms of transformation and upgrading, it is necessary to create a new type of enterprise with six characteristics: First, creating an innovative business model with expanding front-end market R&D and back-end services, and shrinking manufacturing links. Second, from selling goods to selling solutions, enterprises that provide complete solutions. Third, the digital enterprise symbolized by intelligence and integration. A speed-oriented enterprise that doubles in four or five years. Fifth, enterprises with advanced technology, green manufacturing and continuous innovation. Sixth, building high-end products, high-quality products, guide consumption, and brand-winning enterprises. The casting industry will enter into an entirely new area under this industry innovation.
