In the first year after joining the WTO, the Chinese automobile industry developed rapidly. According to statistics, in 2002, the country’s production and sales of automobiles reached 3.477 million and 3.248 million vehicles, respectively, an increase of 38.45% and 38.7% year-on-year respectively. Touching the “10th Five-year Plan†three years ahead of schedule has become the most important driving force for stimulating industrial growth and economic development. One of them is gratifying. In the current situation of the commercial vehicle market "blowout" and the booming production and sales of passenger cars, it is an old topic that the Chinese automobile industry should evaluate its development strategy, and whether it is necessary to adjust or modify the perfection. However, in the face of the trend of multinational corporations participating in the reorganization of Chinese auto companies in their global interests, how to build China's auto industry into a pillar industry of the national economy, and to obtain and maintain the long-term interests of the corporation and the country, this is a It is a major strategic issue that cannot be ignored unless it is prosperous. Second, we should look at the development strategy of commercial vehicles at a higher level. With respect to commercial vehicles, we have more comparative advantages than passenger cars. In order to cultivate and enhance the unique competitiveness of China's commercial vehicles, in the face of WTO entry challenges or multinational companies’ competition, I believe that we cannot discuss the issues on the ground. Many seminars with global strategic issues will only jump out of commercial vehicles and stand on the healthy development of the entire Chinese automotive industry. At a high level, to examine, think and make decisions, the problems revealed in this way will be more profound and the development ideas will be more clear. Third, calm harvest before the prosperity and rational planning business future. In the year of 2002, under the hot background of the automotive market, commercial vehicle companies were able to make profits. In addition to the policy pull on the macro level, a notable feature and main reason was to see who imported the product as early as possible and introduced many technologies. There are few people who profit from the market in the sense of relying on original and innovative new products. The overwhelming majority of companies claim that the growth in benefits comes from product innovation, but it is only adaptive improvement. Although the overall autonomous development capability of commercial vehicles is stronger than that of passenger vehicles, the gap between them and multinational companies is still relatively large. In order to survive the WTO entry, many companies have chosen to reintroduce large-scale or full-scale joint ventures, which is another important feature of the Chinese auto industry after its entry into the WTO. Fourth, what is the decisive factor in forming a weak auto industry development capability? As we all know, the formation of industrial development capacity is affected and restricted by many factors such as industrial capital, technical foundation, human resources, market competition, and policy environment. In the cause of the weak self-development capability of the auto industry (especially the sedan) of our country, although we have seen the difference, although we have seen the wisdom, we have far-reaching influence. From the perspective of the development of resources and the fact that we have objective conditions, etc., it is decisive. I think that when it comes to industrial policy, it is not complete. For example, within a limited (as much as 20 years) protection period, companies have neither enjoyed the encouragement and support of preferential tax policies for the development of national brand cars, nor are they subject to rigid restrictions and assessments due to lack of independent innovation. This objectively led to the intensification of the lack of autonomy of the developer "Meng Ruoxue Xingxing." Among the various factors that shape the development capabilities of the automobile industry, the author believes that only a sound industrial policy can mobilize, integrate, and stimulate the aggregation and amplification of other available resources, and can be based on the country’s existing industrial development resources. To maximize its development capabilities and promote its commercialization and marketization. Industrial policy is not different from the economic system. The strategic role of forming forward-looking, motivating, cohesive, and multiplicative power to develop the industry's ability to independently develop itself has become more prominent as the economy becomes increasingly global. In this regard, people can be confirmed from the PNGV plan launched by the US government at the turn of the century to capture the commanding heights of the 21st century automobile industry, and can also find answers from the successful historical experience of the Japanese and South Korean automobile industry's rapid development. V. Reflections on the Revision of Industrial Policy 1. Correctly distinguish and attach importance to the pillar and shell of the industry. Since the car has developed as a pillar industry of the national economy, its concept cannot be confused. Otherwise, there may be an awkward situation where "where are the guns hit and where are they pointing." I think that the pillar nature of the automobile industry, apart from its general characteristics of growth and stimulating economics, should have the following scientific connotations: Ownership--embodies a strong national spirit of self-reliance, just as if a person had a soul; core--a national brand with more independent intellectual property rights and its market share; Fundamentality - owns independent development capabilities, and its relatively complete industrial system (including joint ventures); benefits - to maximize the long-term fundamental interests of the nation, country, and enterprise. Undoubtedly, once the pillar industry does not possess a vested soul and does not possess the basic and core guarantees and capabilities, it will not be able to maximize its ultimate national interests. Such an industry can only be attached to its "empty shell" industry, and cannot be called a pillar industry of the national economy. The substantive nature of pillar industries cannot be embodied and defined only at the external levels such as taxation and employment. 2. Correctly understand and handle the relationship between joint venture production and independent development. From the highly survey of China’s auto industry as a pillar industry of the national economy, it is clear that we must do a good job of joint ventures and cooperation, but we must not give up the self-development, that is, “open to independent autonomyâ€. I think that dealing with the relationship between the two is like having to plant a "joint venture land," but you can't waste land and "reserve land." Maintaining a certain and necessary independence of the pillar industry can ensure that it will not be controlled by others and that it will ultimately safeguard the country’s economic security and even its political voice. 3. Correctly understand and handle the dialectical relationship between matter and spirit. Following the dialectical materialism, China was able to develop high-tech and products represented by "two bullets and one star" on the basis of the past, on the basis of poverty, and in the new century when the material basis is no longer comparable to the correct understanding and handling of material and spiritual issues. Dialectical relations, in the face of the challenges of China's accession to the WTO, we will surely have greater achievements. In fact, the emergence and growth of new generations of automotive companies (such as Hafei, Brilliance, Chery, Geely, etc.) is enough to eloquently prove the strength and value of the national spirit in the independent development and development of the Chinese automobile industry. 4. Correctly understand the dialectical relationship between practice introduction and innovation. Everyone admits that introduction is a short-cut for development in the case of a temporary lag in technology. But over-reliance on, or even substitute for independent innovation, will enter the backward-introducing-overlapping development cycle. The author believes that: introduction, only medical form; innovation, can cure the problem. Only on the basis of moderate introduction, vigorous efforts to actively digest and independent innovation is the fundamental hope for a healthy and brilliant Chinese auto industry. The establishment of pillar industries in any country cannot be achieved through introduction and re-introduction. This is an inevitable proof that history has repeatedly demonstrated. It is gratifying that, after winning the "World No. 1" award, Liberation Trucks launched a strategic move to turn the world number one into a technologically advanced one. The desire to build a world-class Chinese truck company fully demonstrates the republic. The eldest son's national spirit. Dongfeng Company is not far behind, in the long-term comprehensive cooperation with Nissan, it retained the Dongfeng brand of commercial vehicles, reflected and retained the enterprising spirit, national sentiment and development foundation of several generations of Dongfeng people in the fierce market competition. In the competition and cooperation with multinational corporations, it is still a long way to go to build and upgrade Chinese commercial vehicles with national brands, but there is great hope. 6. Inspire the national spirit and win the development future of independent development of the Chinese auto industry. Comrade Jiang Zemin stated in the report of the 16th National Party Congress that the national spirit is the spiritual support for the survival and development of a nation. A nation that does not have a spirit of exaltation and a noble character cannot stand on its own in the world. I believe that the national brand car is an important carrier and profound embodiment of the national spirit, and it is the external materialization and strength display of the national spirit. The Chinese people have always been proud of the return of the "Red Flag" sedan and advancing with the times; it is not the backbone of the national automobile industry, but also the Hafei people who are also ridiculed; the "outsider" has created "Chinese" brand cars. The people of Brilliance who pursued their own initiative and dared to independently develop “a good car that people can afford†were pursuing the pursuit. These are all indications: In the new situation of joining the WTO, it is valuable and necessary to carry forward and practice the national spirit and independent innovation. The Chinese nation advances with the times and the Chinese people are ardent and diligent. After 50 years of development based on the accumulation of industrial capital and technical experience that cannot be underestimated, as long as we adhere to dialectical materialism and vigorously promote the spirit of national enterprising, our policies are appropriate, our measures are strong, we are consistent from top to bottom, integrate and unite, and work hard to rejuvenate the national automobile industry. It is hopeful that a thriving Chinese automotive industry that is open to the outside world and independently developed will certainly be realized within the important strategic development opportunities of the first 20 years of the 21st century. This is the expectation of generations of automakers! It is also the common aspiration of the Chinese people! Ejector Pins & Sleeves
The use of the thimble and the barrel is called the thimble and barrel assembly, which is one of the plastic mold accessories. The thimble and barrel are the thimble in the barrel and needle assembly. The thimble cylinder is a metal rod used for ejecting the glue product. The product is continuously ejected in the mold running at high speed, and the telescopic movement of the cylinder is used for wear or processing.
1. In plastic molds, separating the product from the mold is also the most commonly used; Ejector Sleeves,Ejector Sleeve Din,Custom Ejector Pin,Ejector Pins And Sleeves Dayue Precision Technology , https://www.dayuechn.com
Not because of happiness, but not because of happiness, for the Chinese automobile industry that started with commercial vehicles, its commercial vehicles with comparative advantages should think and should occupy a place in the world. Under the new situation of joining the WTO, they should speed up independent development and build International brands, this is the real hope for companies to thrive in the near future and reap long-term benefits.
2. Carbide thimble, such as tungsten steel thimble, etc., can be used to pass longer and thinner holes;
3. The thimble is also called the top. It is a conical metal round rod that is mounted on a lathe or grinder to support the workpiece and rotate the workpiece around it, but it is completely different from the thimble of plastic mold accessories;
4. Plastic mold thimble can also be used in the mold, it can play a role of stabilization, and is called as inserting pin.
The types of plastic mold thimble are: flat thimble, dome needle, support pin, standard thimble, non-standard thimble, etc.
Plastic mold thimble materials are SKH51, SKD61, SKD11, 65Mn, etc.
SKH51 thimble has better toughness than SKD61; SKD61 thimble can withstand high temperature of 1600 ℃. After nitriding treatment of SKD61 thimble surface, it can improve the wear resistance of thimble very well. 65Mn thimble is brittle and easy to break because of its poor quality Some plastic molds are no longer assembled and the thimble made of 65Mn is used.
The standard models of lathe and grinder thimble:
The standard for fixed thimble is GB / T9204.1-1988, and the standard for rotary thimble is JB / T3580-1998.
