The next few years will be a period of strategic development for China's industrialization, urbanization, marketization and internationalization. It is also a crucial period for China to build a well-off society in an all-round way. With the further reform of the socialist market economic system, China's piston ring market will become fully open. Modern diesel engines have a wider field of performance in terms of performance - increasing power output, reducing burnup, reducing heat loss and reducing environmental pollution. To this end, many diesel engine parts manufacturers have also been forced to begin to improve its production of components to improve the overall performance of the diesel engine. Piston ring manufacturers are no exception, they use new materials, improve the old manufacturing process.

 

2012 China's domestic piston ring manufacturers, is the second since 2008 and a poor year. Due to the decline in the total installed capacity of commercial vehicles, after-market dealers and customers wait-and-see attitude, the overall market continued to decline, the vast majority of corporate sales decline, profit decline. Passenger car market, although not a significant decline in installed capacity, but because of Japanese damage, German up, independent brand passenger car sales decline and by foreign brands Piston Ring manufacturers squeeze, local Piston Ring enterprises failed to smooth share. In the domestic trapped, at the same time, at the same time, export orders are less and less, Canton Fair, Frankfurt Auto Show, Las Auto Parts Show and other exhibitions is out of doors. Local Piston Ring enterprises without any good news, the industry depressed, looking forward to watching and spent a dismal 2012.

 

Domestic enterprises still have a certain gap in technology research and development, in terms of materials and surface treatment, domestic enterprises are basically no innovation capability; in the product platform validation, the domestic enterprises has just started; domestic enterprises lack of product design experience, In recent years began to accumulate a variety of data; domestic level of equipment affected by the larger, complex products is difficult to ensure the production capacity. Domestic piston ring technology is still in the exploratory stage, although a variety of technology itself has matured, but applied to the piston ring also need to do a lot of research and testing. A variety of new technologies have advantages and disadvantages, the key to solve the quality problem. Domestic enterprises rely on the basic introduction of foreign piston ring technology to improve their technological level.

 

In recent years, the piston ring structure changes little, the researchers mainly in materials and processes to explore. Such as the piston ring surface coating process, although the chemical chrome plating method has been in a dominant position, but a variety of physical spraying new technology has gradually been applied. In addition, the piston ring industry also learn from industry-related technology to improve the level of technology, such as friction surface treatment technology. Piston ring technology there are two trends: First, steel ring. At present, the first ring of gasoline engine has been fully used steel materials, diesel engines use steel ring is also a high proportion. Second, the piston ring height becomes smaller. Piston ring height becomes smaller, the piston ring and the tightness between the liner to strengthen and reduce the chance of oil into the combustion chamber, so that both reduce emissions pollution.
