I. Development Status and Trend of Casting Technology
 
(I) Overview
 
Casting is a liquid metal into the mold cavity after coagulation for metal casting technology, widely used in aviation, spaceflight, automobile, petrochemical, metallurgy, electric power, shipbuilding, textile and other industries, is one of main methods to obtain blank mechanical products and components.
Casting industry in aircraft engine, rocket engines, gas turbine engine, automobile engine, rail transportation occupies a large proportion.It is very important to improve the performance of the equipment.Casting machinery industry is basic manufacturing process.Since 2000, our country has 16 years in a row to occupy the first place of the world casting production,becomes a big casting producer, made a positive contribution for our country national economy development.However, China still lags behind in some high-end casting technology,lead to the development of related high-end equipment lags behind the manufacturing developed countries.There are large numbers of small and medium-sized casting plants in China foundry industry,they all have many problems in the extensive management, backward production capacity and so on, which can cause damage to our ecological environment. Therefore, we need to invest more in energy consumption control and environmental protection.
 
Nearly thirty years, great changes have taken place in the world casting technology,mechanization, automation, digitization and intelligent technology  are continuously developing and deepening, and human beings are increasingly demanding to the sustainable development environment.These factors contribute to the advancement of world casting technology.The next 15 years will be a period of structural adjustment and strategic opportunities for the development of China's foundry industry, and the development of "high-quality, efficient, intelligent and green" casting technology" has become an industry consensus.
 
At present, the development of casting technology goal of China is greatly improve the innovation ability of the high-end castings designed and manufactured by China's equipment manufacturing industry.Become a group of world-class innovations in advanced casting technology, major engineering oversize and key parts of casting forming technology, digital intelligent casting technology, green casting technology. It provides strong technical support for the equipment manufacturing of important sectors of our national economy, and makes our country from the world foundry big country to become the world casting power.
