Fourth, the outlook
In the 21st century , China forging machine tool industry through a variety of ways ( technology transfer, co-production , joint venture ) operations , cooperation with foreign advanced corporate brand products, to enhance the overall level of China’s rapid forging machine tool design and manufacture of many products in recent years , its technical performance has been close to or reach the world advanced level, has made considerable progress in the pleasant aspects . However, well-known foreign companies progress in technological innovation, product development and brand effect areas faster, therefore , the gap between domestic and foreign products forging machine brand without significantly shortened. Faced with this situation , I believe that forging machine tool industry in the future from the following aspects to work on.
⑴ strengthen self-discipline enterprise integration and product structure adjustment . Enterprises should urge the relevant government departments to support the development of industrial planning , and guide enterprises through the development of industrial policy to ｃｒｅａｔｅ and maintain a favorable market environment that encourages fair competition. Under this policy guidance , industry associations and technology to the market trends research, analysis, coordination of corporate behavior , the pursuit of maximizing the efficiency of the sector , companies are seeking self-development in this environment , and seeks to form the government and industry associations positive interaction.
⑵ careful analysis of the gap with the world advanced technology , according to its own conditions, formulate measures to catch up :
① accelerate forging CNC machine tools and flexible than our forging machine developed countries, the low level of NC ( numerical control machine -made rate of less than 5% , Europe, Japan and more than 65% ) , and numerical control systems mainly rely on imports , so in forging machine tool CNC greatly improve and flexible at the same time , but also to intensify the development of China’s own CNC system , CNC machine tools to meet domestic needs ; ② relying on automotive , electronics, high-tech forging equipment industry developed precipitating countries forging machine and both are dependent on the auto industry and the rise of China’s automobile industry is currently flourishing , strong development momentum , coupled with the emerging electronics industry ( telecommunications, data processing, automatic control , home appliances ) , for the development of forging machine , provides a broad battlefield , for which is still an urgent need to develop high-speed stamping equipment behind ( high-speed presses and related automation ) , a large multi-station presses , multi-technology products forming a composite processing unit (laser cutting and CNC punch and automatic loading and unloading of the composite ; uncoiling leveling with laser-cut composite ); ③ focus on developing and supporting parts of the plane with the development of electricity production , transportation, and urban construction on the various profiles processing agenda, therefore , developed and profile processing plane ( complete machining of steel , air conditioning and ventilation tube sets of processing , etc.) promising ; ④ people-oriented development, " green" forging machine for worker safety and pollution of the environment , need to be developed forging machine "Five green " - - green design, green materials, green technology , green packaging and green handle .
⑶ change philosophy, cultivate a world-class brand. Since joining the WTO, the internationally renowned large-scale check- forging machine tool manufacturers in China , the market competition is becoming increasingly international, causing the fall of the domestic high-end market, forging machine , low melee. Faced with this situation, the government and the business community must have a clear understanding. To try to eliminate inter-enterprise internal cut-throat competition , unanimously, make full use of our advantages as the world’s largest machine tool consumer market. From the establishment of institutional innovation , product upgrading, and other brand building and expansion start, efforts to build a national brand ( in 2005 there Jinan Machine Tool Group Corporation, Hubei Tri-ring , Jiangsu Province and Jiangsu Yawei Jinfangyuan founded the National Metalforming Machine brand ) and international brands , and gradually produced a number of internationally renowned Chinese Metalforming Machine products. Fully visible , placed in front of the Chinese people very difficult task of forging long way to go , but as long as we unite as one , adhere to the correct direction , through people’s hard work, China will eventually forging machine into the world power .
