China’s automobile sector has gained a fast development. In 2009, the annual output had reached 13.79 million. And China becomes 1 of world’s biggest car producers. However, some key parts such as bearing bush, axes guide, thrust washers, and auto mold common parts primarily rely on imports which bring both the golden opportunities and wonderful challenges to the Chinese bearing producers and automotive mold manufacturing industries.
At present, China’s resource-saving bearing manufacturing technology which is the independent intellectual house is a lot more material-saving and energy-saving than the standard bi-metal bearing manufacturing technology. It requires less investment and significantly less usage of equipments. Thus, it is an excellent opportunity for improvement. 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 standard and existing sintering bi-metal manufacturing technologies 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 specific shapes, and sliding bearings with strong lubrications, and so forth.
The price of utilization of the steel and copper alloy materials has reached nearly one hundred percent. Because 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-expense and so on. The net shape manufacturing method aids to save supplies and energy so as to provide sliding bearing accessories for the improvement of the China’s automotive industry.
Auto mold business is recognized as “the mother of auto business.” To some extent, the mold sector is the mark to measure the development level of the auto manufacturer or even the national auto sector. Despite the fact that by means of years of improvement, China auto mould technologies and capability has created much progress, it still lags behind in the world automotive manufacturing industries. According to the statistics, about 90% of the auto molds are not “Produced in China”. And the majority of the luxury car molds depend on imports.
There are many recommendations to stick to: firstly, creating a resource-saving sliding bearing manufacturing market with the independent intellectual home. It is not only in accordance with the national policies, but also in line with the policies for the key components of China’s automobile sector development. Apart from, it is an crucial choice for the improvement of the automotive components manufacturing business.
Secondly, we ought to seize the chance of domestication of the automotive components to lay a solid base for the rise of our own auto brands.
