China’s automobile industry has developed rapidly. In 2009, the annual production reached 13.79 million. And China becomes one of the largest automobile producers in the world. However, some key parts, such as bearing sleeve, shaft guide, thrust washers, and standard automotive mold parts, are primarily dependent on imports, providing both golden opportunities and big challenges for manufacturers. Chinese bearing and automobile mold making industries.
At present, China’s resource-saving bearing manufacturing technology, which is independent intellectual property, saves more material and energy than conventional bimetallic bearing manufacturing technology. It requires less investment and less use of equipment. Therefore, it is an excellent development opportunity. Until the end of the patent license of “Self-lubricating composite metal die V-block for automotive molds” in 2009, China had completed the restructuring of the traditional and existing sintering bimetallic manufacturing technology of slide bearings through twenty years accumulation and efforts. . And then China became aware of manufacturing shapes of different categories of bearings that were made of steel and copper alloys. There are bushing bearings, thrust bearings, slide bearings with special shapes, and slide bearings with solid lubrications, etc.
The utilization rate of steel-copper alloy materials has reached nearly one hundred percent. Since then, the slide bearing manufacturing has changed from the rough form of material removal to net form processing which has high efficiency, light weight and low cost, etc. The net form manufacturing method helps to save materials and energy to provide slide bearing accessories for the development of China’s automotive industry.
The auto mold industry is known as “the mother of the auto industry”. To some extent, the mold industry is the brand to measure the level of development of the automaker or even the domestic auto industry. Although over the years of development, China’s auto mold technology and capability has come a long way, it still lags behind in the world’s auto manufacturing industries. According to statistics, about 90% of car molds are not “Made in China”. And most of the luxury car molds depend on imports.
There are many suggestions to follow: First, build a resource-saving slide bearing manufacturing industry with independent intellectual property. It is not only in accordance with the national policies, but also with the policies for the key parts of the development of China’s auto industry. In addition, it is an important option for the development of the auto parts manufacturing industry.
Second, we should seize the opportunity of domestication of auto parts to lay a solid foundation for the emergence of our own auto brands.
