The independent innovation based on the enterprise first depends on the company’s unreliable attitude. The positive action starts with innovation and self-innovation. The company has formed a strong atmosphere of innovation and has gradually accumulated innovative strength. It has already been one step ahead of others. In our engine industry, pistons or piston rings are very small parts. The single value is not high, and we can't create amazing annual production value, but they have already started to take a step forward in product innovation and technological innovation.
Recently, the reporter learned from Yizheng Shuanghuan Piston Ring Co., Ltd. that the market planning of Yizheng double-ring piston rings this year is to support more large international companies and further penetrate the products into the international market. At present, Yizheng double-ring piston rings have been exported to foreign companies such as Japan Komatsu, South Korea Daewoo, Caterpillar of the United States, Italy Iveco and other engine companies, the export volume accounts for about 10% of annual sales, they are expected to increase to three years 30% of the proportion; in China, Shuanghuan is cooperating with Dongfeng Cummins and other joint ventures to provide customers with high-end products.
Yizheng Shuanghuan Piston Ring Co., Ltd. is a joint-venture company established in 1995 by Yizheng Piston Ring Plant of Jiangsu Province and ASIMCO Group with an annual output value of more than 400 million yuan. At present, Yizheng double-ring piston rings account for 25% of the domestic market share. Its leading products account for 70% of the diesel engine used in automobiles.
Yizheng Shuanghuan Marketing Minister Chen Yujin told reporters that Shuanghuan now has its own research and development capabilities, from the initial development of products with the engine host company, can now develop as long as the host company to provide technical parameters, double ring can provide design solutions, make Piston rings that meet customer performance requirements.
At present, the technological level of Shuanghuan, especially the middle-to-high-end piston ring materials and surface treatment technology, has a small gap with international companies. Its self-developed products have reached the international advanced level. The piston ring looks simple, actually involves many fields such as casting, heat treatment, surface treatment, machining, etc. It is a typical labor-intensive, technology-intensive integrated product, especially for the casting, surface treatment requirements are high, its casting, surface Treatment has a great impact on engine performance, emissions, and fuel consumption. In addition, the piston ring operating conditions are rather harsh, not only to withstand the effects of high temperature, high pressure, but also to withstand severe wear and impact load. All of these put very high demands on the piston ring material.
In order to meet the needs of the whole machine, Chen Yujin said that the double-ring piston ring has begun to adopt a steel oil ring adapted to the future development trend of international piston rings. This material is lighter than cast iron and is more suitable for the needs of high-powered engines; in addition, double rings are also introduced. The multi-layer multi-layered nano-piston ring and the composite chrome-plated surface treatment piston ring increase the wear resistance by more than 1.5 times, which is very suitable for medium and heavy truck power. These piston ring high-end products further enhance the competitiveness of the double ring.
In the gasoline engine sector, most of the piston rings of gasoline engines are imported because domestic passenger vehicles use joint venture products. Although domestic products have relatively low costs relative to foreign countries, due to the high value of gasoline engines, the value of the piston rings is relatively small, and it accounts for a smaller proportion of the entire vehicle. Therefore, domestic domestic gasoline engines use a small amount of domestic piston rings. Now Shuanghuan Gasoline Piston Ring is also supporting companies such as Baoding Great Wall, Dongan Mitsubishi, Nanjing Fiat, Zhejiang Geely, etc., and has established joint ventures with Japanese companies to use joint ventures to produce steel rings and double rings to produce cast iron rings. The combination is supported by Japanese Toyota and other host companies.
Yizheng Shuanghuan now has more than 270 technicians. In addition to introducing and digesting NPR's steel ring technology and Germany's Goetz's foundry technology, Shuanghuan also organizes technical personnel to carry out independent development, and has a strong presence in high-grade piston ring materials and surface treatment. Strength. The R&D investment of the company accounts for about 3% of sales each year. This year, the R&D center will also invest 10 million yuan in new equipment, materials, and processes for R&D. It will also work in the area of ​​engine extension such as engine transmission. In addition, Shuanghuan also actively cooperated with Southeast University, Jiangsu University, Hefei University of Technology, Tsinghua University and other universities to jointly tackle some issues.
