Situation About Key Parts of China's Automotive Industry

China's automobile industry has gained a rapid development. In 2009, the annual output had reached 13.79 million. And China becomes one of world's largest car producers. However, some key parts such as bearing bush, axes guide, thrust washers, and car mold standard parts mainly rely on imports which bring both the golden opportunities and great challenges to the Chinese bearing manufacturers and automotive mold manufacturing industries.
At present, China's resource-saving bearing manufacturing technology which is the independent intellectual property is more material-saving and energy-saving than the conventional bi-metal bearing manufacturing technology. It requires less investment and less usage of equipments. Thus, it is an excellent opportunity for development. Until the end of the patent license of "Automotive mold self-lubricating composite metal embossing die V block" in 2009, China had completed the restructuring of the traditional and existing sintering bi-metal manufacturing technology of sliding bearing through twenty years' accumulation and efforts. And then China realized the shape manufacturing of different bearing categories which made from the steel - copper alloys. There are bushing bearing, thrust bearing, sliding bearings with special shapes, and sliding bearings with solid lubrications, etc.

The rate of utilization of the steel and copper alloy materials has reached nearly one hundred percent. Since then, the manufacture of sliding bearings have changed from the rough shaping of the material removal into a net shape processing which has high efficiency, light weight, and low-cost and so on. The net shape manufacturing method helps to save materials and energy so as to provide sliding bearing accessories for the development of the China's automotive industry.
Auto mold industry is known as "the mother of auto industry." To some extent, the mold industry is the mark to measure the development level of the car manufacturer or even the national auto industry. Although through years of development, China auto mould technology and capability has made much progress, it still lags behind in the world automotive manufacturing industries. According to the statistics, about 90% of the auto molds are not "Made in China". And the majority of the luxury car molds depend on imports.

There are many suggestions to follow: firstly, creating a resource-saving sliding bearing manufacturing industry with the independent intellectual property. It is not only in accordance with the national policies, but also in line with the policies for the key parts of China's automobile industry development. Besides, it is an important choice for the development of the automotive parts manufacturing industry.
Secondly, we should seize the opportunity of domestication of the automotive parts to lay a solid base for the rise of our own auto brands.
