How influential is the production of precision parts in the mechanical industry

Precision parts processing components are constantly rising, and the construction machinery industry will continue to operate at a high level. However, while China's construction machinery industry further develops, it is still constrained by components. At present, the vast majority of key components, including hydraulic components and transmission systems, need to be imported from abroad, which leads to high production costs and a lack of international competitiveness for domestic complete machine enterprises.

For a long time, the products of domestic component enterprises have struggled to meet the supporting requirements of host enterprises, making imports the only choice, especially in excavator products. The import price of components is expensive, resulting in 70% of the profits of the construction machinery industry being consumed. Faced with excessive dependence on components, the construction machinery industry is still a hindrance to progress. It is expected that by the end of the 12th Five Year Plan, China's construction machinery sales will reach 900 billion yuan and export value will exceed 26 billion US dollars.

Key components of construction machinery are the foundation, support, and bottleneck for the development of construction machinery products. When construction machinery reaches a certain stage of development, high-tech research in the industry mainly focuses on key components such as engines, hydraulics, transmission, and control technology. After the high-end technology manufacturing of basic components is placed in China, a large number of equipment and technologies supporting this component will gradually mature.

1. Localized production, shortened ordering and delivery times, production close to users, and professional production to form a reasonable economic scale for the manufacturing of key components while ensuring component quality and relying on components to achieve the technical characteristics of the enterprise itself.

2. Pay attention to the integrated design of key components and the host, as well as further improve the standardization and generalization rate of components, to maximize the simplification of maintenance.
