In the past, the production and processing of die-casting molds mainly relied on fitters, or the extensive workshop-style production management model centered on fitters, but now it is gradually being replaced by an intensive modern production management model based on technology and centered on design; die-casting molds The traditional concept of products is also being replaced by the concept that die-casting molds are high-tech products, such as smart die-casting molds.
Since the "Tenth Five-Year Plan", under the support and guidance of national policies, the die-casting mold industry has invested heavily, the equipment level and strength of the enterprise have been greatly improved, the production technology has made great progress, and the CAD/CAM technology has been popularized; hot runner technology and more Station progressive stamping technology has been better promoted; CAE, CAPP, PLM, ERP and other digital technologies have been adopted by some companies and have received good results; high-speed processing, concurrent engineering, reverse engineering, virtual manufacturing, and non-graphic production And standardized production has been implemented in some key backbone enterprises.
The advancement of technology has promoted the level of die-casting mold products to be greatly improved in recent years, and the trend towards high-end development is more obvious. Some die-casting mold products have reached or are close to the world’s advanced level. Among them are the giant die-casting molds with a single set of die-casting molds weighing 120 tons, and ultra-precision die-casting molds with a processing accuracy of 0.3-0.5μm, and a service life of 300 million ~ 400 million times long-life die-casting molds, high-speed precision stamping die-casting molds that can be matched with 2500 times per minute high-speed punches, multi-functional composite die-casting molds that can realize multi-material and multi-process forming, complex die-casting molds that can achieve intelligent control, and so on.
However, from the perspective of the production and demand situation of die-casting molds, the supply of medium and low-end die-casting molds has exceeded demand, while the self-sufficiency rate of high-tech die-casting molds represented by large-scale, precise, complex, and long-life die-casting molds is still low, only about 60%. Most of it still relies on imports. At present, plastic die-casting molds account for the largest proportion of the total sales of die-casting molds, accounting for about 45%; stamping die-casting molds account for about 37%; casting die-casting molds account for about 9%; other types of die-casting molds total about 9%.
The operating characteristics of the die-casting mold industry in 2010 indicate that the industry’s structural adjustments in the past five years have achieved results. From the understanding of the association, it can be clearly seen that large-scale, precise, high-efficiency, and high-performance die-casting molds are the main representatives of medium and high-end die-casting. The proportion of molds continues to rise, and the product level is greatly improved. At the 13th International Die-casting Mold Technology and Equipment Exhibition in 2010, there were 181 die-casting molds that won the "Precise Mold Award", including 55 first-class awards and 64 second-class awards, which are not only larger in number than before Increasing, and the level has also been greatly improved, more and more projects have reached the international level, innovation is obvious, and patents are increasing. The gap between the average unit price of die-casting mold imports and exports is shrinking, which also reflects the improvement of the overall level of my country's die-casting mold industry and the progress of science and technology.
In 2010, my country’s per capita plastic consumption was about 46 kg, only 1/3 of that of developed countries. This indicates that my country’s plastic products industry will continue to develop at a high speed during the “Twelfth Five-Year Plan” period. Under the inevitable trend of replacing wood with plastic, the engineering plastic products industry is expected to maintain an average annual market growth rate of 15% during the "Twelfth Five-Year Plan" period. It can be imagined that the plastic die-casting mold, which accounts for the highest proportion of the total die-casting mold, will also develop at a higher growth rate during the "Twelfth Five-Year Plan" period.
In addition, as the automobile industry that uses the largest amount of die-casting molds, it is expected to grow at an average annual growth rate of about 10% during the "Twelfth Five-Year Plan" period. The maintenance parts market and export market driven by 76.193 million vehicles and 94.53 million motorcycles). China’s auto parts will also maintain a relatively high growth rate on the basis of a huge market of 1.5 trillion yuan. It is therefore expected that the "Twelfth Five-Year Plan" "During this period, the average annual growth rate of automobile die-casting molds will not be less than 10%, and the average annual growth rate of rubber die-casting molds, including automobile tire die-casting molds, will reach more than 10%.
The electronics and information industries are also big users of die-casting molds, and the "Twelfth Five-Year Plan" is expected to have an average annual growth rate of about 20%.
Rail transit, aerospace, new energy, medical equipment, building materials and other industries will also bring a huge market for die-casting molds. For example, for medical equipment, my country currently only accounts for 2% of the world’s share. The consumption ratio of medicines to medical equipment is only 2.5:1, while that of developed countries is 1:1. The average annual consumption cost of medical plastics in the United States is US$300, while China only has RMB 30 shows the great potential for development.
Therefore, according to estimates by the China Die-casting Mold Industry Association, by 2015, my country’s total die-casting mold sales may reach about 174 billion yuan, of which the proportion of high-end die-casting molds will reach more than 40%.
In the international market, due to the continuous increase of labor costs in industrialized developed countries, they are forced to continuously transfer die-casting molds to developing countries, especially those with a better technological foundation like my country, in order to reduce production costs. The trend of multinational companies coming to my country to purchase die-casting molds is still under development, and the development of international emerging markets is also promising.
However, in the development of the market, the requirements for die-casting molds are increasing. For example, emerging industries such as automotive lightweighting, smart forming, new energy, aerospace, biomedicine, rail transit, smart grid, etc. are all national development priorities during the "Twelfth Five-Year Plan" period. The die-casting molds needed for these priorities are naturally die-casting. Many of the development priorities of the mold industry require new development, and many technologies need to be broken through. It is necessary to use this as a breakthrough to drive the improvement of the overall level of the industry.
The service life of die-casting molds in my country is low (the life of fine punching dies is generally only about 1/3 of the advanced foreign level), the long production cycle, poor quality reliability and stability and other long-term problems that have plagued the development of the industry need to be resolved in the next step. At the same time, my country also has a large gap in research and development capabilities, personnel quality, basic theories and technology research on die-casting mold design and manufacturing, etc., which has caused a slower pace in the development of new areas of die-casting molds and the development of new products. The proportion of high-tech die-casting molds is much lower than that of foreign countries (about 60% abroad, less than 40% domestic).
It took us more than 10 years for the export of die-casting molds to exceed US$100 million, and it took 7 years to develop from US$100 million to US$1 billion. Now the export is close to US$2 billion. It can be said that my country’s die-casting mold industry has a considerable foundation. .
However, if the base is large, to achieve the goal of doubling exports in five years during the 12th Five-Year Plan period, it is necessary to actively cultivate export bases and key export enterprises. Of course, expanding foreign trade and developing exports is not only to achieve the export goal of 4 billion US dollars, but more importantly, to achieve integration with the international market through the completion of this task, to promote my country's die-casting mold technology and the comprehensive level of the industry. improve.
On the basis of serving traditional manufacturing industries such as machinery, automobiles and electronic appliances, many new products will also serve the seven strategic emerging industries of new energy, medical equipment, aerospace, energy conservation and emission reduction.

"In 2010, the total sales of die-casting molds nationwide reached about 112 billion yuan, an increase of more than 14% over the previous year." Qin Ke, deputy secretary-general of the China Die-casting Mold Industry Association, told reporters that this shows that my country's die-casting mold industry has gained a lot in the post-crisis period. Good recovery growth, and the growth rate has reached double digits again.
Small, sophisticated and specialized are the characteristics of the industry
Die-casting molds are extremely important and indispensable special basic process equipment in industrial production. For industry to develop, die-casting molds must go first. And because the die-casting mold production process integrates precision manufacturing, computer technology, intelligent control and green manufacturing, it is both a high-tech carrier and a high-tech product. Due to the high production efficiency, high consistency, low energy consumption, and high precision and complexity of the mass production of parts using die-casting molds, it has been increasingly valued by various industrial production departments of the national economy.
The vast majority of die-casting molds are produced in a single piece for a specific user. Therefore, compared with general industrial product companies, die-casting mold companies are large in number and small in scale, and most of them are small and medium-sized enterprises. Die-casting mold products have high technical content, a large proportion of activated labor, a high value-added rate, and a long production cycle. Therefore, the die-casting mold manufacturing industry has technology-intensive and capital-intensive, balanced production and business management difficult, and special users Dependence, the burden of value-added tax, the slow accumulation of corporate funds, and the long payback period of investment. Due to the wide variety of die-casting mold products, the size is very different, and the requirements are different. Therefore, the development of die-casting mold enterprises is suitable for "small and precise, small and specialized, small and special"; industry development is suitable for concentrated production and cluster development to establish a comparative Strong collaboration supporting system. This is also one of the important characteristics of the die casting mold industry.
According to the 2008 my country Industrial Census, there are about 30,000 die-casting mold manufacturing enterprises (factories, sites) nationwide, with nearly 1 million employees, of which there are more than 2,800 die-casting mold manufacturing companies with a main income of more than 5 million yuan across the country. More than 400,000 employees are employed.
