The piston ring, as the heart of the internal combustion engine, is exposed to high temperatures, high pressure, corrosion, and acts as a seal, support, lubrication, heat transfer, etc., under conditions in which the engine's internal working environment is harsh. The piston ring industry is an industry that combines technology-intensive and labor-intensive and requires large investment, and is closely related to the development of modern internal combustion engines and automobile industry. In 2010, the automobile piston ring industry, like the development of China's whole machine industry, won rapid growth. However, when we review the development process, we must consider some deep-seated problems.

The "Mood, Fury, and Joy" of the Automotive Piston Ring Industry in 2010

In 2010, China's auto sales exceeded 18 million vehicles, becoming the world's largest automobile in a veritable world and setting a record high. Piston ring products are used in the field of internal combustion engines with an annual output of 70 million units, including various fields such as automotive and non-vehicle use. In the maintenance market, according to statistics, China’s vehicle ownership exceeded 70 million in 2010, and China still has a large number of agricultural machinery, which has brought rare opportunities for vulnerable parts such as piston rings.

The rapid growth of the host market and foreign trade market has brought sweetness to parts and components companies, but most companies are limited by capacity. Host companies' peak season installed capacity exceeds the average monthly average of more than 30%, and their monthly capacity is severely unbalanced. In addition, for companies with installed equipment as their main market, the after-sale maintenance market is also intentionally or unintentionally “seasonally marginalized.” The true and false debates and confusions of the maintenance market are related to the conscious non-standard dominance of market leaders. The survival path of many small businesses that do not match with the mainframe is to “trim the ball.” Many companies that do not even have their own trademarks, which have always been manufactured in a “neutral packaging” can survive, and many dealers profit at a high rate. For the purpose of concentrating on promotion of inferior or mixed products. The monopoly system only gave suppliers or product codes to the original suppliers of the parts and components. Many OEMs' monopoly systems were basically unregulated, and anti-counterfeit measures were basically unsound or unsound. Some small factories have caught the loopholes of the host companies and also catered to the interests of some non-monopoly system distributors.

The rapid growth of the passenger vehicle market has also brought about an increase in the demand for piston rings. However, in the high-end passenger vehicle piston ring market, the monopoly of foreign companies is still difficult to shake. Japanese and Korean descent passenger cars, and Japan and South Korea parts and components to establish a strategic system, although entering China, its stable self-supporting system does not easily change; Europe and the United States passenger car support system although open, but it must obtain a series of certification, Strict requirements for process consistency, implementation of global procurement, in the new round of competition, the national piston ring advantage is not obvious. The domestic self-owned brand passenger car is the main market for national brand piston rings, and it is also the competitive goal of overseas piston ring enterprises to expand the Chinese market. In the competition with foreign companies on the same stage, the most fierce trick adopted by domestic products is the price “diving”.

"Twelve Five" Automobile Piston Ring Industry's "Fourizations" Target

- "Internationalization", technology research and development, and internationalization of talent to enhance core competitiveness.

R&D competition is the core competition of the “Twelfth Five-Year” piston ring industry. At present, many companies in the industry are propagating the simultaneous development of an engine or an auto manufacturer. They are actually manufacturing, not real design. The internationalization of technology for piston ring companies means that we will never have to draw on drawings and processing, and develop synchronously with the main engine plant, and we will reserve the technology for future delays, and support and guide the development of the engine and automobile industry. The current lack of local piston ring companies is that they have not yet mastered the future of the industry can lead the industry's cutting-edge technology, at most only in the "painting", to the parameter design stage, even if the design of the verification method is often still rely on the whole plant Or foreign research institutions. The internationalization of the talent team is also an urgent need for the development of the piston ring industry. At present, there is a special need for engineers who can both speak other languages ​​and understand technology.

- "Modularization", follow the component supply trend, and take the road of scale development.

Now the piston ring industry, the combination of supply has been common, the modular supply of the host market in the gasoline engine industry has been one step ahead, in the diesel engine industry also has a rapid development trend. In addition to its own brand passenger cars in the main engine field of gasoline engines, the purchase of piston rings has been very few. On the one hand, in order to reduce the assembly process and save costs, on the one hand, in order to shrink the core supplier team, on the one hand, piston rings and other related parts Purchasing requirements are assembled after assembly and delivery.

In the aftermarket market, the modularity of the piston rings is by no means new. 80% of light trucks in the diesel engine market are sold as components (four matching/six packages, cylinder liners, pistons, piston rings, piston pins, retainer springs, etc.), and nearly half of the heavy trucks are sold as components. The rapid expansion of sales of components in the aftermarket has a bearing on too many domestic engine deformation products. The repair shop is not clear about the configuration of the product; on the other hand, it is related to the technical level of repair personnel in the auto repair industry. In some areas of the industry, it can be called "Change workers" instead of "repair workers."

-- "Informationization" to accelerate the integration of "two industries" and realize the information integration of manufacturing equipment.

Informatization is not just the last ERP system of the company, office automation, establishment of CRM, etc. The ultimate goal is to infuse information throughout the entire process of manufacturing, namely, equipment automation, site management, production, and informatization of technology systems. Currently, one of the gaps between the advanced piston ring enterprises in the industry and foreign countries lies in the information integration of equipment. There are few automated production lines in China, most of which are still stand-alone operations, and are supplemented by clusters of machines in the local area. However, it has not been fully promoted, mainly due to cost and technical issues. Leading companies in the domestic piston ring industry have introduced foreign advanced equipment in the key processes, key processes, and testing of key projects in the production and processing of piston rings. They have also played their due role in the production of piston rings, but their performance remains to be furthered. Play. If further integration with domestic equipment in information technology, the automation level of piston ring leading enterprises will leap to a new level, and the entire industry will also undergo a revolutionary change.

- "Standardization": The management and market will be gradually standardized, and the real integration with international companies will be achieved.

In the face of fierce competition in the domestic and international markets, the piston ring enterprises are experiencing technological maturity and stability. On the one hand, they are under pressure from price drop and price competition. On the other hand, they face cost challenges. The era of low-cost is getting farther and farther. The high-cost era is gradually approaching, and financial costs, raw material power costs, logistics costs, labor costs, and environmental costs are rising every year. In the same stage competition with foreign counterparts, when foreign counterparts monopolize a certain product market, its price is a strong high price. Once the domestic national brands have been successfully developed, foreign brands have substantially reduced their prices and their profit margins have been greatly reduced. Foreign counterparts can achieve low costs without deducting gross profit. However, domestic counterparts have to spend a lot of money. At present, in the national brand passenger car market that has been purchased at a low price, foreign counterparts in the piston ring are also eyeing and will also enter the market as one of the indicators for corporate assessment. The piston ring industry will launch a further "cost war." In this way, digesting and reducing costs, carrying out meticulous management and implementing lean manufacturing will be the only way for the piston ring industry to go.
