Answer: In the new era of big data, traditional foundry enterprises and traditional production methods have been seriously challenged. "Intelligent casting", "digital" these new words bring hope also brings confusion. What is the specific "intelligent casting"? How far is it from us? "Intelligent casting" is the product of the high integration of informatization and casting production, including intelligent casting technology and intelligent casting system. Intelligent casting technology includes numerical simulation, 3D printing, robot, ERP, etc. Intelligent casting system is a big data knowledge base with learning ability, which can carry out self-planning and self-improvement through comparative analysis of environmental information and its own information. The typical application mode of "intelligent casting" is "digital foundry". The "digital foundry" all uses information technology to manage all internal processes such as production process, quality control process, financial process, product development process, human resource management training process, etc. At the same time, it uses information technology to deal with the related processes with suppliers and customers. The entire production process can be simulated and controlled. In the "digital foundry", heavy manual labor is basically eliminated, 80% of employees can work in air-conditioned rooms, the environment is clean, and the production efficiency and efficiency are greatly improved. "Intelligent casting" is not far away from us. At present, many domestic factories have begun to build "digital foundries" or "intelligent foundries", and they will meet with you one after another during the "13th Five-Year Plan" period.

The equipment and technology required for "intelligent casting" are becoming more and more mature in the Chinese market, and will be systematically demonstrated at the "14th China International Foundry Expo": one of the necessary equipment and technologies for intelligent casting is rapid prototyping equipment. Rapid prototyping is divided into additive rapid prototyping (or 3D printing) and subtractive rapid prototyping, both of which have the characteristics of rapid free forming with or without molds, near net forming of complex components and even net forming, full digitization, high flexibility, and multi-material arbitrary composite manufacturing. It is an effective tool for the rapid development of new products, and it is also an essential production equipment for "intelligent manufacturing.

The second of the necessary equipment and technology for intelligent casting is the robot. Accuracy and high efficiency are the typical characteristics of intelligent casting, and robots are the ideal choice for "intelligent casting" and the necessary production equipment. In the "numerical foundry", robots are widely used in modeling, core making, pouring, cleaning and other processes to work side by side with workers or independently.

The third of the necessary equipment and technology for intelligent casting is simulation. In recent years, China's casting simulation technology in the light metal material casting forming research and development momentum, in aluminum, magnesium alloy casting and solidification process macro/micro modeling and simulation research, casting filling solidification process micro simulation has made important progress. The scale of microscopic simulation includes nano-scale, micron-scale and millimeter-scale, involving crystal nucleation growth, dendrite and columnar crystal transformation to metal matrix control and other aspects. In addition, quality control simulation is developing in the direction of microstructure simulation, performance and service life prediction.

The fourth of the necessary equipment and technology for intelligent casting is virtual manufacturing. Virtual manufacturing is one of the effective ways for "digital foundry" to improve production efficiency, including virtual design, virtual inspection, simulation analysis, etc., through the "human brain computer" with big data resources, to find and solve the problems of product quality, cost, efficiency, key parameters and so on before formal production, so as to greatly improve production efficiency and product quality. At present, these virtual manufacturing technologies are becoming more and more mature in China.
