Automotive air conditioning system compressor is the heart of the entire air conditioning system, and a swash plate compressor is compressor key parts, its quality directly affects the quality of work and life of the compressor, but due to casting technology and anti-friction material immature technology, China swash plate has been dependent on imports, thereby constraining China's automobile manufacturing domestically. 
Conventional swash plate made ​​of cast copper alloy, when the lubricating oil is a working refrigerant mixture in the form of oil mist lubrication, and a great part of the lubricating oil is stopped will be taken together with the refrigerant, when the when you restart, the swash plate and the shoe at the relatively oil-free state, it is prone to sliding shoe and swash plate surface killed, so the life of this traditional product accordingly subject to certain restrictions. Further, a copper alloy casting costs are relatively high. 
In order to solve the initial stage compressor start lubrication conditions are very poor working conditions issues and reduce the production cost of the swash plate, China in recent years there has been a work surface using both sides of the sintered steel base material layer of copper powder form structure, due to copper alloys containing lead elements of this solid lubricating materials, so use effect greatly improved. Its about technology as "steel base material + + self-lubricating surface pretreatment copper layer + precision machining." 
With automotive technology development, energy crisis highlights and people's awareness of environmental protection, automobile air conditioning compressor also moving toward lightweight, high-performance, variable-displacement, high-speed, electronic and environmentally friendly, such as the direction of rapid development. Swash plate technology has also been improved, high-performance self-lubricating swash plate has become more than two swash plate upgrading of products, such as the use of a sliding layer containing a thermosetting resin and a solid lubricant in the swash plate surface. However, due to limited patents and technology, the new product technology has been in the hands of a handful of Japanese companies. Therefore, increase R & D investment in the product, and gradually realize the localization of products and industrial imperative.
