China’s automobile industry has gained a rapid development. In 2009, annual output reached 13.79 million. And China is one of the biggest car manufacturers in the world. However, some important parts such as bush bearings, axle guides, thrust washers, and auto mold parts mainly depend on imports which bring a golden opportunity and a big challenge for Chinese bearing manufacturers and the automotive mold manufacturing industry.

At present, China’s resource-efficient bearing manufacturing technology, which is an independent intellectual property, is more material-efficient and energy-efficient than 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 …
