WHAT IS PRECISION CASTING ?
Precision casting is the general term of precise casting technology obtained by precise molding method. Precision casting is a metal forming object obtained by precision casting, that is, the molten metal is injected into the prepared mold by pouring,
injection, inhalation or other casting methods, and then cooled to obtain the object with certain shape, size and performance.
Precision casting includes: investment casting, ceramic mold casting, metal mold casting, pressure casting, lost foam casting. One of the most commonly used is investment casting, also known as lost wax casting: select suitable investment materials
to make investment mold (such as paraffin); repeatedly dip refractory coating and sprinkle refractory sand on the investment mold to harden and dry the mold; then melt the internal investment mold to obtain the mold cavity; roast the mold shell to
obtain sufficient strength, and burn off the residual investment material; pour the metal materials required for pouring; Solidification cooling, shelling after sand cleaning, so as to obtain high-precision products.
The precision and complexity of the product obtained by investment casting is close to the final shape of the product. It can be directly used without processing or less processing. It is an advanced process of near net shape formation and an excellent
process technology in the casting industry, and its application is very extensive. It is not only suitable for casting of various types and steel materials, but also can produce castings with higher dimensional accuracy and surface quality than other casting
methods, and even the complex, high temperature resistant and difficult to process castings that are difficult to be cast by other casting methods can be cast by Investment precision casting.
Main function Due to the rapid development of modern metal parts, such as the rapid development of metal parts, such as the core and shell of aircraft, and the rapid development of precision metal parts, such as the core and shell of the gun, the rapid development of the precision casting of metal parts, such as the core and shell of the gun, the rapid development of the precision metal parts, such as the core and shell of the gun, the rapid development of the precision metal parts, such as the core and the shell of the gun, the rapid development of the metal parts and the shell of the gun, the gun head and the metal parts of It has been widely used in casting stainless steel, titanium alloy, aluminum magnesium alloy and so on. Alloy and Al Mg alloy have been widely used in casting.

Investment casting industry analysis Under the influence of global economic integration, the world civil investment casting market has shifted to China, and China has accelerated the development of aerospace industry, which makes China's precision casting industry become the fastest growing industry in China. On the one hand, the total amount is constantly increasing. Taking the civil silica gel process investment casting as an example, in the past five years, the number of factories has increased at the rate of 10% - 15%, and the output has increased by 20% - 25%. On the other hand, the level has been continuously improved, especially the aerospace investment casting has continuously introduced advanced technology and equipment from abroad, and the product quality level has approached the level of developed countries.
| Expansion capacity With the improvement of parts requirements, more and more sand castings or forgings will be replaced by investment castings. With the continuous improvement of the industrial chain of China's precision casting industry and the continuous improvement of technical level, the demand for precision casting parts in the downstream demand areas is increasing. It can be seen that the output of precision casting parts in China will continue to show a steady growth trend in the next few years. The market scale of China's precision casting industry will continue to show a steady growth trend. It is estimated that by 2021, the market size of China's precision casting industry is expected to be close to 285 billion yuan.
