Participating enterprises of aviation components in precision parts processing

In precision parts processing, aviation component subcontracting enterprises can be divided into four categories. The first type is the internal supporting component production unit of the main engine factory, which is the main participant in domestic aviation component production. In addition to supporting its own complete machine, it also undertakes international subcontracting orders; The second type is aerospace research institutions with supporting production capabilities, such as aviation manufacturing institutes, which gradually form a certain scale of component production capacity during the research and development process of special materials or special processes, mostly supporting their own research and development activities. Their technical advantages are mainly reflected in some high-tech components.

The third type of precision parts processing is a joint venture of international aviation parts manufacturing enterprises in China. These enterprises have high management and technical capabilities, advanced production equipment, and mainly engage in international subcontracting business; The fourth type of enterprise is a private aviation component manufacturing enterprise, which mostly provides targeted supporting services for the main engine factory.
