In today’s era of rapid development of science and technology, the aerospace field as the forefront of human technological challenges, the requirements for materials and manufacturing technology are increasingly demanding. Die casting technology, as a kind of precision casting process, its application in aerospace is deepening, and it is gradually becoming one of the key factors to promote the progress in this field. Let’s discuss the development process, current situation and future trend of die casting technology in the aerospace field, aiming to provide reference and inspiration for research and development and manufacturing in related fields.

Die casting technology has been widely used in aerospace field because of its high efficiency, high precision and ability to produce complex shape castings. From engine components to structural frames to the manufacture of precision instruments, die casting technology provides components with excellent performance and high precision.

1、In the aerospace field, the performance requirements of materials are extremely high, including high temperature resistance, corrosion resistance, light weight and high strength.

Traditional die casting materials such as aluminum alloy can not fully meet these extreme requirements, so the research and development of new die casting materials has become the focus of technological development. Titanium alloy, superalloy and so on began to be widely used in die casting production, these materials not only have better mechanical properties and heat resistance, but also can maintain stability in more harsh environments.

2、With the advancement of modern aerospace technology, the requirements for precision and complexity of components are also increasing.

The traditional die casting technology is easy to produce defects such as pores and shrinkage holes in the production process, which is difficult to meet the needs of high precision. Therefore, high-precision die casting technologies such as vacuum die casting and low-speed die casting have been developed, which significantly improve the internal quality of castings by improving the filling and solidification methods in the die casting process.

3、The aerospace industry has extremely high requirements for the reliability of parts, and any small defect can lead to serious consequences.

In order to ensure the quality of die casting parts, various advanced inspection and quality control technologies are introduced into the die casting production line. Non-destructive testing technologies such as X-ray testing and ultrasonic testing can find small internal defects without damaging the casting. At the same time, through real-time monitoring of the working state of the die casting machine and the quality data of the casting, the production process can be optimized and quality control can be achieved.

4、In the quest to be more efficient and economical, the aerospace sector is also working to reduce its environmental impact.

The improvement of die casting technology in environmental protection has become an important research direction. Die casting production is becoming greener by adopting environmentally friendly coatings, reducing emissions of harmful substances, and recycling die casting waste.

5、Looking to the future, die-casting technology has great potential for development in the aerospace field.

With the continuous emergence of new materials and new processes, the performance of die-casting parts will be more superior, and the application field will be further expanded. The promotion of intelligent manufacturing and Industry 4.0 will make die casting production lines more automated and intelligent, not only improving production efficiency, but also achieving a higher level of quality control.

The rapid progress in the aerospace field has put forward higher requirements for die casting technology, but it also provides a broad stage for its development. Through continuous technological innovation and improvement, die casting technology is expected to provide more high-performance and high-quality parts for the aerospace field, and help the breakthrough and application of aerospace technology.
