Data reveals gaps in standard parts between China and foreign countries

On April 26, Chen Xufeng, a parts exhibitor at the 2010 Beijing International Auto Show, came to the booth early in the morning and waited for the arrival of China National Heavy Duty Truck General Cai Dong. In fact, Chen Xufeng, the chairman of Longzhong Machinery Holding Group, has been in contact with Cai Dong for a long time. Cai Dong came here to see the products of Longzhong and the second is to discuss the cooperation.

The whole vehicle company talks about cooperation, and it is naturally a happy thing for the parts and components enterprises. But what makes Chen Xufeng more excited is what will happen recently. Multinational commercial vehicle companies such as Volvo in Sweden and Linan in India will send people to Longzhong to inspect the package.

"As long as the foreigner can go to me, the package is basically no problem. Because we have the same commitment as the international brand, the price is lower than them, why not use us." Chen Xufeng dared to say such a big thing because he The company has a verification system that is synchronized with foreign countries. This system guarantees that its products can meet international standards.

For a long time, the development of China's parts industry has lagged behind and it has become a pain for Chinese people. The headlines of “self-reliance of parts and components” and “difficulties in independent research and development of parts and components” have become the generalization of the development of China's parts industry. In this context, people hope that more and more parts companies like Longzhong will appear at the same time, and they are also analyzing the question mark. How can China's parts industry be stronger?

A few years ago, Hadex, Sweden, the world's largest manufacturer of automatic adjustment arms, used the Chinese-made automatic adjustment arm to test the Chinese market. The test results were only one-half of Hadex's 2.5 million times. 5. A few years later, the standards of many Chinese companies have remained at the current industry standard of 500,000 times. What is the difference in quality between 500,000 and 2.5 million?

Chen Xufeng, who is engaged in the manufacture of automatic adjustment arms and disc brakes, told reporters: "The automatic adjustment of the arm of 500,000 times for the bus means a half-year service life. If the test standard is 2.5 million, the automatic adjustment arm can use three. In fact, this is the gap between us and the world. This gap is also reflected in the pneumatic disc brakes. Most of the domestically produced pneumatic disc brakes currently stay on the reliability test of 500,000 times. The standard for pneumatic disc brakes is 2.5 million as with the automatic adjustment arm."

What causes such a big gap? Chen Xufeng believes that there is no standard testing in the industry, and the company has no verification system, which makes the quality control of the product difficult, resulting in the technology can not be upgraded.

Chen Changnian, director of the equipment department of China Automotive Engineering Society, pointed out in an interview that the test standards, testing methods and testing techniques of auto parts have lagged behind the development of domestic parts manufacturing industry, which restricts the domestic auto parts industry. development of.

Chen Xufeng told reporters: "To meet the standards required by multinational corporations, enterprises must formulate technical requirements and test methods. In order to make the technical requirements reflected on the products, the test projects should cover all standard requirements. For example, the automatic adjustment arm The test includes adjustment torque test, hysteresis test, limit temperature test, anti-corrosion test, fatigue endurance test, dust test, static strength test, dynamic test. To do these tests, real money needs to be invested." Chen Xufeng told reporters that The input of the automatic test arm gantry test line is 800,000 Euros. These test equipments basically run 24 hours without stopping, and fully test the performance of the products.

In fact, the product verification system is not only to control quality standards, but more importantly, it has a lot to do with independent research and development. If the product is designed, can it meet the design requirements, it is necessary to verify and obtain data through experiments. If there is a defect, it is corrected by the test, and so on, and finally the design requirements are met.

Chen Xufeng told reporters that in 2004, Longzhong began to develop disc brakes. After four years of verification, it reached the standard of 2.5 million times abroad. 24 hours of continuous testing, only a month of electricity costs more than 10,000 yuan.

"In my words, research and development must be able to withstand loneliness, because we manufacture car brakes, and a slight oversight will lead to traffic accidents." Chen Xufeng said. For this reason, the uninterrupted verification and adjustment made Chen Xufeng the same commitment as the European manufacturer, two years or 300,000 kilometers without failure, many domestic counterparts are one year or 80,000 kilometers without failure.

On the surface, 500,000 times and 2.5 million times is just a simple digital concept. In fact, the difference of 2 million times reflects the true level of China's auto parts industry. What are the standards for safety-related parts, so what about the standards for other parts? So, how can China's auto parts industry become stronger?

In fact, under the influence of the financial crisis, many multinational giants are trying to digest production capacity. China's huge market is attracting multinational companies to invest and build factories in China. It is in this context that WABCO has come to China. Liu Liang, president of WABCO Asia Pacific, said that the establishment of a brake production base in China marks WABCO's strategic presence in China's growing market.

Competition is intensifying and the price of pneumatic disc brakes is falling. When multinational companies first entered China, the price was more than 10,000 yuan, and now the price of multinational companies is only 3,000 yuan, which is only about 500 yuan higher than domestic enterprises. Once WABCO's pneumatic disc brakes are put into production, multinational companies are likely to use their capital and brand advantages to further squeeze Chinese companies. This is the status quo. If we do not improve our standards as soon as possible, the living space of local parts companies will become smaller and smaller.
