[Summary]1. Overview of Precision Casting
Precision casting is the general term for precision casting technology. Precision casting is a metal forming object obtained by precision casting, that is, molten liquid metal is poured into a pre-prepared casting mold through pouring, injection, suction or other casting methods, and then cooled to obtain a certain shape, Size and performance. The shape of the object.
Precision casting includes investment casting, ceramic casting, metal casting, pressure casting and lost foam casting. Among them, investment casting is more commonly used, also known as lost wax casting: select suitable investment materials (such as paraffin) to make investment; repeated use of refractory coatings and sandblasting processes on the investment, harden the shell and dry; when investment casting , Using heat treatment process. When melting the internal investment mold to obtain a cavity; calcining the shell to obtain sufficient strength and burn off the residue. Mold materials; metal materials required for pouring; solidification, cooling, shelling, sand cleaning, so as to obtain high-precision products. According to product requirements or heat treatment, cold treatment and surface treatment.

2. Production and sales of precision castings in China
In recent years, my country's investment casting industry projects have continued to increase and production capacity has continued to increase. In 2015, my country's investment casting output exceeded 2.2 million tons.
In recent years, the downstream demand areas of my country's precision casting industry have continued to expand, and the demand for precision casting has continued to increase. In 2015, the market size of China's precision casting industry exceeded 110 billion yuan.
3. Enterprises in my country's precision casting industry
With the continuous improvement of the industrial chain and technical level of my country's precision casting industry, the demand for precision casting in downstream demand areas is also increasing. It can be seen that in the next few years, my country's investment casting output will continue to grow steadily. It is estimated that by 2021, the output of precision castings in my country will be close to 4.6 million tons.
With the rapid development of my country's economy, the domestic precision casting market is expanding day by day. For example, the rapid development of the automobile industry has driven the rapid growth of automobile precision casting product output and brands, and the development of the residential construction industry has led to a sharp increase in the demand for construction hardware. Chinese investment companies directly purchase parts and components from the region, and the original international market orders have become. Domestic market orders, etc., the demand for investment casting in downstream demand areas is only increasing. It can be seen that the market scale of my country's investment casting industry will continue to grow steadily in the next few years. It is estimated that by 2021, the market scale of my country's precision casting industry will be close to 285 billion yuan.
