The leading mold technology level of modern industrial molds depends to a large extent on the overall level of talents, and the level of mold technology determines the quality and effectiveness of products and the ability to develop new products. Therefore, mold technology has become a measure of a national product. The important symbol of the level of manufacturing.
The development and improvement of the mold industry will certainly play an important role in building an innovative country in China. According to foreign statistical data, the proportion of molds that can drive its related industries is about 1:100, that is, mold development is 100 million yuan, which can drive related industries to 10 billion yuan.
Dies are not mass-produced products, they have a single piece of production and depend on specific users. As far as the mold industry is concerned, the introduction of foreign advanced technologies cannot adopt the usual methods of introducing product licenses and technology transfer, but mainly introduce cad/cam/cae software and precision processing equipment that have already been commercialized, and introduce foreign molds for advanced manufacturing. Concepts, the introduction of foreign mold advanced manufacturing personnel, the use of Chinese and foreign mold design, hire foreign experts to develop their own national mold industry. The integration of cad/cae/cam and cad/cae/cam of the mold covers a wide range of fields and integrates various disciplines and engineering techniques. It is an integrated and technology-intensive product. Modern molds must realize digital design, digital manufacturing, digital management, and digital production processes. Without the digitization of molds, there will be no modern molds. The cad/cae/cam technology of the mould is changing with each passing day. The important task is to follow-up the secondary development of the imported software. The mold talent naturally shoulders the promotion of the software and the secondary development of the software. From this perspective, the mold high technology Talent also plays a role in the research and redesign of mold related fields.
The development of molds is like a breakthrough. China's mold industry has developed rapidly in recent years. According to incomplete statistics, in 2004 there were more than 30,000 mold manufacturing plants in China, employing 800,000 people. In 2005, the development of the mold industry maintained a good momentum. Adequate orders, full missions, mold sales of 61 billion yuan, an increase of 25% over 2004, at the same time, China's mold production technology has greatly improved, mold production level has reached or reached the international level. Die imports reached US$2.068 billion in 2005, an increase of 14.07% over the previous year, indicating that high-tech molds are still far from meeting the needs of the domestic market. In 2005, China's mold exports reached 738 million U.S. dollars, an increase of 50.31% over the previous year. The ratio of imports and exports in 2005 was 2.8:1, which is more reasonable than the 3.69:1 in 2004. In 2005, the total import and export volume of molds in China reached 2.806 billion yuan, and the net import after import and export reached US$1.33 billion, which is a country with a large net import volume. In 2006, China's mold industry will continue to see significant growth. Molds with high technological content will still be the focus of national development.
Among the more than 30,000 mold manufacturing enterprises, there are more than 20 mold enterprises with over 100 million yuan in output value, dozens of medium-sized enterprises with output values ​​of 50 million to 100 million yuan, and enterprises with an output value of about 20 million account for a large proportion. Due to the improvement of the overall mold level, the digitization of the mold processing equipment and the lack of map design of the mold make the entry threshold of mold enterprises reach a higher level. Modern molds require the mold industry to accelerate the pace of structural adjustment. According to the import and export situation in 2005, plastics and rubber molds imported 1.145 billion U.S. dollars, accounting for 55.4% of total imports, and exports 532 million U.S. dollars, accounting for 72.1% of total exports, which is equivalent to the previous year, indicating that the plastics and rubber molds are still relatively Good level. The import of stamping dies was 726 million U.S. dollars, accounting for 35.1% of the total import volume. Exports were 146 million U.S. dollars, accounting for 19.8% of the total export volume. This was a significant increase from the same period of the previous year. The proportion of stamping die exports increased, indicating that the stamping die level increased significantly. In addition, large-scale, sophisticated, complex, long-life high-grade molds and mold standard parts develop faster than general mold products. The number of professional mold factories has increased, and their capacity has increased rapidly. "Three-funded" and private enterprises have developed rapidly, and the transformation of the joint-stock system of state-owned enterprises has accelerated.
The mold industry is becoming bigger and stronger In 2005, the mold industry also showed several other features. First, local governments are paying more attention to the development of the mold industry. Many local governments have recognized the importance of the mold industry in the development of manufacturing, and have therefore strengthened the construction of the mold industry park. The existing parks have been further expanded, with mold zones such as Ningbo Yuyao, Ninghai and Suzhou Kunshan all expanding. The new mold industry park is stepping up construction, Chengdu has established the mold industry promotion office, and Chongqing, Dalian, Shenzhen, Suzhou and other mold parks have been established. In addition, Shenyang, Xi'an, Shanghai, Ningbo Beilun, Zhejiang Huangyan and other places are actively preparing for the establishment of a mold industry park. Promote clustering, and gradually form a mold industry chain with reasonable division of labor, complete facilities, and close cooperation, in order to facilitate the development of regional molds and related industrial chains and even the development of manufacturing industries. Some high-tech park mold enterprises already occupy a considerable amount, like Tianjin Hi-tech Zone has more than 40 mold companies.
Second, the foreign investment and social investment mold industry has grown significantly. Many places have strengthened the work of attracting foreign investment and joint investment in the mold industry, especially in high-tech parks and industrial parks. Foreign-funded, Hong Kong-funded, and Taiwan-funded mold and die enterprises have further increased, such as Suzhou Kunshan Mould Park, where more than 60% are foreign-funded enterprises. The Dalian Mould Park attracts investment from Japan and South Korea. In some areas of high-tech parks, driven by the development of the automotive industry, mold and die enterprises have taken up considerable weight. For example, in the Tianjin Hi-tech Zone, there is the world-famous Japan Toyota Motor Mold Company. At the same time, the social investment mold industry has also been strengthened.
In terms of regional distribution, the southeastern coastal areas centered on the Pearl River Delta and the Yangtze River Delta (the mold output has accounted for about 70% of the national total) has grown faster than the central and western regions. At present, the provinces with the fastest growing and more concentrated mold production are Guangdong, Jiangsu, Zhejiang, and Shanghai. In 2005, the regions with an import of molds exceeding RMB 100 million in China were ranked in descending order of Guangdong, Jiangsu, Shanghai, Tianjin, Zhejiang, Beijing, and Jilin. It can be seen that the continuous development of the automobile industry and IT industry in the above areas has led to a strong demand for molds and the prosperity of mold companies. The regions with the highest total export volume were the same as those in 2004, and still followed by Guangdong, Zhejiang, Shanghai and Jiangsu. This shows that the southeast coastal areas with the Pearl River Delta and the Yangtze River Delta as the center still maintain the leading status of mold manufacturing as a whole.
The market for mould equipment is huge According to relevant agencies, in 2005 there were about 870 manufacturers of machine tools (including forming machine tools) in China, with sales revenue of 51.9 billion yuan and total machine tool output of 450,000 units, an increase of 12.7% over the previous year. Among them, the output of CNC machine tools was about 60,000 units, a year-on-year increase of 14%. In 2005, the number of imported machine tools was 116,600 units, a year-on-year decrease of 9%, and the amount of foreign currency exchanged was 6.5 billion U.S. dollars, an increase of 10% year-on-year. We estimate that the total domestic machine tool consumption in 2006 will be about 12 billion US dollars, equivalent to about 97 billion yuan (including forming machine tools). The level of our country's mold production process equipment is low, and we need to develop vigorously and acquire a large amount of advanced equipment. The average value of the output value of fixed assets investment and mold growth in the mold industry is roughly 1:1. The input of enterprises with rapid development period and strong growth can reach 1:1.5 or even 1:2. Investment in fixed assets, mold processing equipment More than 80% investment. The sales growth of 8 billion yuan in 2005 means that the demand for mold processing equipment is about 10 billion yuan, and the input of the mold companies is long-term and sustainable. As the mold products are divided according to the high, middle and low-end markets, the natural mold processing equipment is also high-middle and low-end.
At present, the key development direction of mold processing is no map production, single-piece high-precision parallel processing, less humanized unmanned processing, and CNC machine tools are required to meet high speed, high dynamic accuracy, high rigidity, thermal stability, and high reliability. And the associated control system, all kinds of advanced software for the integrity of the machine, the most important thing is that the three-dimensional mold surface processing special attention to the dynamic performance of the machine.
Japan, Europe and the United States in the high-end tooling manufacturing equipment, measuring equipment, monopoly position, of course, is due to the high quality and their products can not be separated, but also with their strategy for the Chinese mold market. Their demand for the mold market is an active service. They cooperate with the mold users to develop the mold-specific functions of the machine tools and to customize the functions. Japan's Mori Seiki Co., Ltd. quickly entered the Chinese market. The first institute they established in China was to study mold manufacturing technology. At the forthcoming 11th China International Mould Exhibition, Japan Makino Company will display a super spark machine, super horn function, so that the r angle is 0.01mm, super surface function, no pinholes on the processing surface. In terms of processing centers, China imported 10,343 units in 2005, amounting to 1.297 billion U.S. dollars. It can be said that the medium-to-high-grade machining centers that the mold industry purchases abroad account for a large proportion. Korean machine tools and Taiwanese machine tools have a good price/performance ratio in mid-range models, and they are also very attractive to mainland mold companies.
Because more than 80% of electrical processing equipment is used for mold processing, most domestic electric processing equipment companies need to develop electrical processing equipment for the mold industry. The precision can meet the needs, the market is widely distributed, and middle and low-grade electric processing equipment has an absolute advantage. Other types of processing machines The advantages of domestic machine tools are not obvious, and their use ratio is not high. There are about 500 domestic gold-cutting machine tools and 150 CNC machine tools. There are dozens of companies that are capable of manufacturing mold-processing equipment. However, the number of machine tools entering the mold-making industry is far from this figure. The 100 million mold processing equipment market is still far from the attention of domestic equipment companies.
The mold development trend puts special requirements on the mold processing equipment.
1. The increasing size of die-molded parts and the high productivity of parts require a multi-cavity mold, resulting in an increasingly larger die, large-tonnage large-scale die up to 100t, a die cavity of several hundred, thousands of cavity, requiring a large workbench of die processing equipment , increase the y-axis z-axis travel, large load-bearing, high rigidity, high consistency.
2. The hardness of the mold steel material processed by the mold is high, and the mold processing equipment is required to have thermal stability and high reliability.
3. For complicated cavity and multi-functional compound molds, with the complexity of the shape of the parts, the level of design and manufacture of the mold must be improved, and a variety of grooves and various materials must be formed or assembled into a multi-functional composite assembly in one set of molds. The mold requires a large amount of processing and programming procedures. It has a high deep hole cavity comprehensive cutting capacity and high stability, and improves the processing difficulty.
4. High dynamic accuracy. The static performance (such as the repeat positioning accuracy and linear feed speed) introduced by the machine tool manufacturing enterprise cannot reflect the actual machining situation when machining the three-dimensional mold surface. The high-precision processing of the three-dimensional surface of the mold has brought forward the requirements of high dynamic precision performance, and high-speed high-precision can be realized only when the high rigidity, thermal stability, high reliability, and high-quality control system of the machine tool are matched.
The key development areas address the future development of mold products and put forward requirements for mold processing equipment.
Automotive cover molds. In order to meet the continuous development of the automotive industry, the automotive parts molds that are manufactured for a large number of new models are bound to develop at a high speed, requiring the automotive cover mold companies to have shorter processing cycles and higher machining accuracy. At present, gantry CNC milling machines, five-face CNC milling machines, high-speed CNC milling machines, gantry coordinate measuring machines, three-dimensional five-axis laser cutting machines, and research and development presses are key processing equipment, and at the same time, supporting high-quality control System, CNC machine network access cam software has a great market.
Large and medium-sized precision plastic molds. Large-scale precision plastic molds are mainly used in industries such as automobiles and home appliances. They are used to make bumpers, dashboards, fuel tanks, steering wheels and other molds for automobiles, and large and medium-sized plastic molds for color TVs, washing machines, refrigerators, air conditioners, and other household appliances. From the perspective of domestically produced moulds, they account for about 60% of the market share. Many large and medium-sized plastic mold manufacturing companies are also increasing investment to improve production capacity and mold manufacturing levels as soon as possible. To this end, high-speed machining tools, CNC boring and milling machines, machining centers, large-scale electric processing machine tools, deep-controlled drilling machines, CNC grinding machines, prototype machines, measuring equipment and scanners and other key equipment and cad/cam/cae software market can not be underestimated.
Small and medium precision molds. There are many kinds of these kinds of molds and they have a wide range of services. The rapid development of the information industry manufacturing industry and the electromechanical industry are their largest markets. Mobile communication equipment, microcomputers, monitors, integrated circuits and other products have strong demands on small and medium-sized precision molds, so that such mold manufacturing companies maintain strong purchasing power for some precision equipment, high-precision machining centers, and high-precision CNC grinding machines (coordinate grinding, light Curved mills, forming mills, and plane grinding machines, high-precision electric machine tools, high-precision measuring equipment, die steel heat treatment equipment, surface hardening equipment, and design and processing software all have a large market.
Mold standard parts. At present, there are relatively large quantities of mold standard parts that are mainly used for molds, guides, punches, push rods, push tubes, elastic components, etc., oil mold guides for automotive molds, wedges, and so on. These products not only have a large number of domestic needs, but also export. The prospects are also very good. The next few years will continue to be vigorously developed. Foreign large-scale mold standard parts companies have started to take a break in China. It is necessary to expand the variety of mold standard parts, improve its accuracy, increase production concentration, and achieve large-scale production. The use coverage of mold standard parts increased from the current approximately 45% to 60% in 2010. For this reason, there will be a large market for machining centers, CNC lathes, CNC milling machines, CNC boring and milling machines, centerless mills, and cylindrical grinding machines.
The modern mold industry is a technology and capital-intensive industry. Modern molds are process-intensive industries with a high-tech background and high-tech talent-intensive industries. As an important production equipment industry, it serves all industries and industries and also directly serves the high-tech industry. Due to the production of molds, a series of high technologies are used, such as cad/cae/cam/capp and other technologies, computer network technology, laser technology, reverse engineering and concurrent engineering, rapid prototyping technology and agile manufacturing technology, high-speed machining and super-finishing, and micro-machining. Processing, compound processing, surface treatment technology, etc. Therefore, the mold industry has become an important part of the high-tech industry.
