Current situation and development trend of injection mold in China
Current situation and development trend of injection mold in China
Plastic products are widely used in daily society, mold technology has become one of the important symbols to measure the manufacturing level of a country's products. Domestic injection mold in quality and quantity have a rapid development. However, compared with foreign advanced technology, most enterprises in China are still in the critical period of technical transformation, technological innovation, product quality improvement, modernization management and system transition.
About the regional distribution of the national plastic processing industry, the pearl river delta, the Yangtze river delta plastic products processing industry ranked the forefront, zhejiang, jiangsu and guangdong plastic mold output value in the national total mold output value proportion also accounted for 70%. Now, many enterprises in these three provinces have realized the unlimited business opportunities of plastic mold industry and are actively organizing the development and manufacturing of mold products.
Plastic products in the automotive, mechanical and electrical, instrumentation, aerospace and other national pillar industries and related to People's Daily life in various fields have been widely used. Plastic products forming method although many, but the most important method is injection molding, the world plastic mold market plastic mold production in about half of the injection mold.
At present, there are more than 30,000 mold manufacturing plants in China, with more than 800,000 employees. In 2005, the export of moulds reached 740 million us dollars, up about 50% from 490 million us dollars in 2004, ranking among the top in the world. In 2006, China's total output value of plastic mold more than 30 billion yuan people's development, China's largest injection mold single set of weight has exceeded 50 tons, the most accurate injection mold precision has reached 2 microns. Parts of high precision small module gear mold and meet the requirements of the high optical lamp mould has also can produce, such as multi-cavity plastic mold has been able to produce 7800 - mould cavity thanks, high-speed mold has been able to produce out up to 6 m/min speed or high speed plastic different profile extrusion die and the main profile double cavity co-extrusion, double color, currency, which exports about 5.8 billion yuan. In 2006, the total demand for plastic molds in China was about 31.3 billion yuan, the total supply of domestic molds was about 23 billion yuan, and the market satisfaction rate was 73.5%. In China, guangdong, Shanghai, zhejiang, jiangsu and anhui are the main production centers. Guangdong accounts for 40% of the total production of moulds in China, the proportion of injection moulds is further increased, the level of hot runner moulds and gas auxiliary moulds is further improved.
Injection mold in the quantity and quality of fast extrusion, hard and soft co-extrusion, after co-extrusion, re-extrusion and low-foaming steel co-extrusion and other molds. With the popularization of CAD/CAM technology, the application of CAE technology is becoming more and more extensive. With the development of CAD/CAM/CAE- systematization, the innovative achievements of new mold structure, new varieties, new technology and new materials keep emerging, especially the rapid development of automobile, household appliances and other industries, which makes the rapid development of injection mold.
As a whole, China's plastic molds have made great progress in terms of quantity, quality, technology and capability, but still far behind the needs of national economic development and the world's advanced level. Some large, sophisticated, complex, long life of high-grade plastic mold still need to import a lot every year. In total demand at the same time, - some low-end plastic mold oversupply, market competition is fierce, there are some technology content is not too high in the middle of the plastic mold oversupply trend. After recent years of development, plastic mold has shown some new trends:
1. Vigorously improve the development ability of injection mold.
Push the development as far as possible, until involved in the mold user's product development, even before there is no clear user object development, become passive to active.
At present, TV set and display shell, air conditioner shell, motorcycle plastic parts have used this method, mobile phone and telephone mold development has begun to try. This practice has broken the long - term mold factory can only wait for a contract, according to customer requirements for mold design passive situation.
2. The injection mold has changed from relying on locksmith technology to relying on modern technology.
With the improvement of mold enterprise design and processing level, the manufacture of injection mold is changing from relying on the technology of fitter to relying on technology. This is not only the change of means of production, but also the change of mode of production and the rise of ideas. This trend leads to the continuous improvement of mold standardization, higher and higher mold accuracy, shorter and shorter production cycle, lower and lower proportion of fitters, and finally promotes the overall level of mold industry to continuously improve.
At present, there are more than 10 national high-tech enterprises and about 200 provincial and municipal high-tech enterprises in China. In line with this trend, it is an inevitable requirement that the main backbone force of mold production gradually changes from technical talents to technical talents.
3. Mold production is developing rapidly to informatization.
In the information society, as a high-level modern mold enterprise, the application of CAD/CAM alone is far from enough. At present, many enterprises have adopted CAE, CAT, PDM, CAPP, KBE, KBS, RE, CIMS, ERP and other advanced manufacturing technologies and virtual network technologies, which are all manifestations of informatization. The trend toward informatization has become the consensus of the industry.
4, injection mold to a wider range of development.
With the continuous progress of human society, the mold will inevitably develop to a wider field and a higher level. Now, can grasp the opportunity, develop the market, constantly find new growth point of mold enterprises and can produce high-tech mold enterprises business is very prosperous, the level of profit and staff income are very good. Therefore, mold enterprises should grasp this trend, and constantly improve the comprehensive quality and international competitiveness.
With the development of the market, plastic new materials and diversified molding methods will inevitably continue to develop in the future, so the mold requirements are higher and higher. In order to meet the needs of the market, the future plastic mold no matter the type, structure, performance or processing will certainly have rapid development. Super large, super precise, long life, high efficiency mold; A variety of materials, a variety of colors, multi-layer and multi-cavity, a variety of molding methods integrated mold will be developed. New materials for molds with higher performance and for special purposes will continue to evolve, resulting in a special and more advanced processing method. A variety of mold cavity surface treatment technology, such as coating, repair, grinding and polishing and other new processes will continue to develop. China's plastic mold industry and foreign advanced level, the main problems. 1. Unbalanced development
The overall product level is low. Although the products of some enterprises have reached or approached the international advanced level, but in general, the accuracy of the mold, cavity surface roughness, production cycle, life and other indicators and foreign advanced level still have a big gap. The overall level, including production methods and enterprise management, is still more than 10 years behind that of foreign industrialized countries.
2. Backward technology and equipment, poor organization and coordination ability.
Although some enterprises through the technological transformation in recent years, the level of technological equipment has been relatively advanced, some enterprises in the three capital level of equipment is not behind the foreign countries, but most of the enterprise's technological equipment is still relatively backward. More importantly, the organization and coordination ability of enterprises is poor, it is difficult to integrate or mobilize social resources for our use, so it is difficult to undertake relatively large projects.
3. The contradiction between supply and demand cannot be alleviated in a short period of time.
In recent years, domestic plastic mold domestic market satisfaction rate - straight less than 74%, which large, precision, long life mold satisfaction rate is lower, estimated less than 60%. At the same time, industrial developed countries mold is accelerating the transfer to China, more and more international procurement, international market prospects. The market is in great demand, production is still struggling to keep up, and demand will outstrip supply for some time to come.
4. Most enterprises are weak in development and innovation.
On the one hand, the proportion of technical personnel is low and the level is not high enough. What's more, the concept is backward and there is not enough attention to innovation and development. Mold enterprises should not only pay attention to the development of mold, but also pay attention to product innovation. This not only requires plastic machinery enterprises in technical personnel, technical innovation to have strong strength, but also requires enterprises to accurately grasp the personalized needs of customers in the first - time.
The level of mold production technology is not only an important indicator of a country's product manufacturing level, but also to a large extent determines the country's product quality, efficiency and new product development capacity. China's current mold development and manufacturing level than the international advanced level at least 10 years, especially large, precision, complex, long life mold production and demand contradiction is very prominent, has become a serious constraint to the development of China's manufacturing bottleneck.
Mold is the basis of industrial process equipment, in the telecommunications, automotive, motorcycle, machinery, electrical appliances, instruments, household appliances, building materials and other products, to 80%. On all want to depend on the die forming, with mold production parts of high accuracy, high complexity, high consistency, high productivity and low consumption, is can't be matched by other processing methods. Therefore, we should have a clear understanding of the situation and focus on the right direction to speed up development, instead of relying on imports forever. Of course, in recent years, China's injection molding industry development speed can not be underestimated, we should take this opportunity to catch up with the developed countries in the shortest time.
Although plastic molds have become the most attractive "cheese" nowadays, cherries are tasty and hard to plant. Due to the complex shape of plastic parts, flexible design, mold materials, design level and processing equipment have higher requirements, not everyone can easily set foot in. Experts believe that there is still a big gap between China and foreign countries, the current need to break through the three bottlenecks restricting the development of the mold industry as soon as possible: one is to increase the research and development of plastic materials and injection molding process; Second, plastic enterprises should develop to the park, accelerate the integration of resources; The third is the mold test results inspection and other tooling level must keep up as soon as possible, otherwise the development of plastic mold will be restricted
Mold enterprises should through cooperation, integration and other ways, the single fight, vicious competition for win-win cooperation, break the "peer is the enemy" of narrow thinking, through industry self-discipline to maintain the mold market fair, healthy competition.
In recent years, the pace of mold industry structure adjustment has been accelerated, mainly manifested as the development rate of large, precision, complex, long-life mold and mold standard parts is higher than the overall development rate of the industry; The proportion of plastic mould and die casting mould increases; The number and capacity of professional mold manufacturers facing the market increase rapidly. In the future development direction of China automobile mould company, we should pay attention to the adjustment and positioning of product structure, improve the manufacturing technology level of the mould, and occupy the high-grade mould market with complex structure, high precision and high technical content.
It is understood that with the deepening of the reform and opening up policy, the state departments concerned to the mold industry attention and support, coupled with the mold industry association and other social organizations propaganda and promotion, so that the mold industry in zhejiang more rapid development, mold market size in the country ranked the first.
During the 12th five-year plan period, the general trend of mold market is stable and upward. At present the domestic market to the high - grade mold demand is very big, but the domestic mold must be in the quality, delivery time and other aspects to meet the needs of users. Moreover, home appliances, automobiles and plastic products industries have the greatest demand for molds. International market: in recent years, labor costs in industrialized countries have increased and are being transferred to developing countries, especially southeast Asian countries. Its home to produce high, fine mold based, manual labor input into the mold depends on the import solution. Therefore, the international market potential of mid - and low-end mold is very great. As long as the quality of the domestic mold can be improved, the delivery time can be guaranteed, mold export prospects are very optimistic. In addition, the international market for frame and mold standard parts of the demand is also very large. At present, our country has a small number of exports only to frame.
Although the total production of China's mold has ranked third in the world, the industry is not lack of some good overall level of the enterprise manufacturers, but at present the characteristics of the domestic mold industry is manufacturers uneven technological conditions, the gap is very large. Quite a few are private enterprises or self-employed, limited by capital, site, technology, information exchange and many other factors, some manufacturers rely on traditional equipment and manual manufacturing, can only produce some medium and low grade molds, it is difficult to introduce advanced molding technology and advanced molding equipment. This has resulted in increased competition in the mid - and low-end mold market. Some mold enterprises in order to work, not hesitate to reduce the price of each other, and low price is bound to affect the quality of products, the result is pit users, the same trade, but also harm themselves.
From China mold and die industry development planning study to understand market prospect analysis and investment is the focus of the mold industry development in the future can not only meet the needs of the large, and have high technical content, especially in the current domestic is not self, to a large number of imported mould and can represent the development direction of large-scale, precision, complex, long-life mold, also because our country mold large price advantage in the international market, export prospects good mould product will also become the focus of development.
Dating back to 10 years ago, the accuracy of precision molds was generally 5 microns, and as time goes on, the accuracy of molds will become higher and higher. It has now reached 2~3 microns, and a 1-micron precision mold will be on the market soon. This requires superfinishing. Mold industry will become larger and larger. This is due to the mold forming parts are increasingly large and high production efficiency requirements and the development of a mold cavity caused. The multi-function compound mould will be further developed in the mould industry. In addition to the new multi - functional composite mold pressure molding parts, but also responsible for stacking, tapping, riveting and locking assembly tasks, the performance of steel requirements are higher and higher.
In particular, the home hardware industry needs continuous development and innovation, the industry for home hardware demand is growing, home hardware industry presents a different change. Many furniture hardware manufacturers separate the two intangibles, decorative hardware does not pay attention to functional development, functional hardware on its decorative development research is insufficient, there is a disconnect between the two.
Mould industry is an important part of the hardware industry in China, the 12th five-year period is the major change environment, properly deal with the domestic and foreign development in our country to speed up the key period to realize the comprehensive construction well-off society goal, also is the key to the healthy development of the mould manufacturing industry in China, the domestic and foreign environment, although there are many uncertain factors, but the economic development of our country is still in the growth period, the comparative advantage of die mold in the international market in our country still exists, the domestic mold market expectations also continues to look good, mould industry development trend.
