The current situation and development trend of Chinese injection molds

Date of Release:2021-06-13  Click:1008

Plastic products are widely used in daily society, and mold technology has become one of the important indicators to measure the manufacturing level of a country's products. Domestic injection molds have developed rapidly in both quality and quantity. However, compared with foreign advanced technologies, most of China's enterprises are still in a critical period that requires technological transformation, technological innovation, product quality improvement, modern management, and institutional transition.

Regarding the regional distribution of plastic processing industry in the country, the plastic products processing industry in the Pearl River Delta and the Yangtze River Delta is in the forefront, and the proportion of plastic mold production value in Zhejiang, Jiangsu and Guangdong accounts for 70% of the total mold output value. Now, many companies in these three provinces have realized the unlimited business opportunities in the molding industry and are actively organizing the development and manufacture of mold products.

Plastic products have been widely used in various pillar industries such as automobiles, electromechanical, instrumentation, and aerospace, as well as in various fields related to people's daily lives. Although there are many methods for forming plastic products, the most important method is injection molding. About half of the plastic forming molds in the world plastic mold market are injection molds.



At present, there are about 30,000 mold manufacturing factories in China, with more than 800,000 employees. In 2005, mold exports reached 740 million US dollars, an increase of about 50% from 2004's 490 million US dollars, ranking first in the world. In 2006, the total output value of plastic molds in China was about 30 billion yuan.


The development of China's largest injection mold has a weight of more than 50 tons, and the precision of the most accurate injection mold has reached 2 microns. Small-modulus gear molds with high precision of parts and headlight molds for high optical requirements have also been produced. Multi-cavity plastic molds have been able to produce a 7800-cavity plastic mold, and high-speed molds have been able to produce extrusion speed. High-speed plastic profile extrusion die of 6m/min or more and double-cavity co-extrusion of main profile and two-color coin, of which the export value is about 5.8 billion yuan. In addition to self-production and self-use, in terms of market sales, the total demand for plastic molds in China was about 31.3 billion yuan in 2006, and the total supply of domestic molds was about 23 billion yuan, with a market satisfaction rate of 73.5%. In China, Guangdong, Shanghai, Zhejiang, Jiangsu and Anhui are the main production centers. Guangdong accounted for 40% of China's total mold production, the proportion of injection molds further increased, and the level of hot runner molds and gas-assisted molds further improved.

Injection molds have various types of molds such as quick extrusion, soft and hard coextrusion, post coextrusion, re-compressed re-compressed and low-foamed steel-plastic co-extrusion. At the same time that CAD/CAM technology has become popular, CAE technology has become more and more widely used, and CAD/CAM/CAE integration has been developed. Innovations in new molds, new varieties, new processes and new materials are emerging, especially in automobiles. The rapid development of industries such as home appliances has led to the rapid development of injection molds.

Overall, China's plastic molds have made great progress in terms of quantity, quality, technology and capabilities. However, compared with the needs of national economic development and the world's advanced level, the gap is still large. Some large, sophisticated, complex, long-life mid-to-high-end plastic molds still require large imports every year. At the same time that the total supply is in short supply, some low-end plastic molds are oversupplied, and the market competition is fierce. There are also some mid-range plastic molds with less technical content, which also have a tendency to oversupply.

After several years of development, plastic molds have shown some new development trends:

1. Greatly improve the development capability of injection molds.

Push the development work forward as much as possible until it is involved in the product development of the mold user, even before the development of the user object is clear, and become passive.

At present, TV and display housings, air conditioner housings, motorcycle plastic parts, etc. have adopted this method, and the development of mobile phone and telephone molds has also begun. This kind of practice has broken the passive situation that the mold factory can only wait for the contract to be able to design the mold according to the user's requirements.

2. Injection molds have changed from relying on fitter skills to relying on modern technology.

With the improvement of the design and processing level of mold enterprises, the manufacture of injection molds has changed from relying on the skills of fitters to relying mainly on technology. This is not only a change in production means, but also a change in production methods and an increase in ideas. This trend has led to the continuous improvement of the standardization of the mold, the higher and higher precision of the mold, the shorter and shorter production cycle, and the lower and lower proportion of the fitter, which has finally promoted the overall improvement of the overall level of the mold industry.

At present, there are more than 10 state-level high-tech enterprises in China, and about 200 provincial and municipal high-tech enterprises. In line with this trend, it is inevitable that the main backbone of production molds will gradually change from skilled talents to technical talents.

3. Mold production is rapidly developing into information technology.

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 informationization. The trend towards the development of information technology has become an industry consensus.

4. Injection molds are developed to a wider range.

With the continuous advancement of human society, molds will inevitably develop into a wider range of fields and higher levels. Now, the mold enterprises that can seize the opportunity and open up the market, and constantly discover new growth points and the business that can produce high-tech mold enterprises are very prosperous, and the profit level and employee income are very good. Therefore, mold companies should grasp this trend and continuously improve their comprehensive quality and international competitiveness.

With the development of the market, new plastic materials and diversified molding methods will inevitably continue to develop in the future, so the requirements for molds are also increasing. In order to meet the needs of the market, the future plastic molds will have a rapid development in terms of variety, structure, performance and processing. Ultra-large, ultra-precision, long-life, high-efficiency molds; molds with multiple materials, multiple colors, multi-layer, multi-cavity, and multiple molding methods will be developed. New materials for higher performance and special-purpose molds will continue to evolve, resulting in special, more advanced processing methods. Various mold cavity surface treatment technologies, such as coating, repair, grinding and polishing, will continue to evolve.

Compared with the advanced level in foreign countries, China's plastic mold industry mainly has the following problems.

1. Unbalanced development

The overall level of the product is low. Although the products of individual enterprises have reached or are close to the international advanced level, overall, the accuracy of the mold, the roughness of the surface of the cavity, the production cycle, the life span and other indicators are still far from the advanced level. The overall level, including production methods and business management, has a gap of more than 10 years compared with developed industrial countries.

2. The process equipment is backward and the organization and coordination ability is poor.

Although some enterprises have undergone technological transformation in recent years, the level of process equipment has been relatively advanced, and the equipment level of some foreign-funded enterprises is not behind that of foreign countries, but the technological equipment of most enterprises is still relatively backward. More importantly, the organization and coordination ability of enterprises is poor, and it is difficult to integrate or mobilize social resources for me to use, so that it is difficult to undertake relatively large projects.

3. The contradiction between supply and demand is difficult to ease in the short term.

In recent years, the domestic market satisfaction rate of plastic molds has been less than 74%, of which large, precision, long-life molds have a lower satisfaction rate, estimated to be less than 60%. At the same time, molds in industrialized countries are accelerating their transfer to China, and international procurement is increasing, and the international market is promising. The market demand is strong, production development is still difficult to keep up with, and the situation of short supply will continue for some time.

4. Most enterprises have weak development capabilities and their innovation capabilities are obviously insufficient.

On the one hand, the proportion of technicians is low and the level is not high enough. On the other hand, there is less investment in scientific research and development; more importantly, the concept is backward and insufficient attention is paid to innovation and development. Mold companies should not only pay attention to the development of molds, but also pay attention to product innovation. This requires plastic machinery enterprises to have strong strength in technical talents and technological innovation, and also requires enterprises to accurately grasp the individual needs of customers in the first time.

The level of mold production technology is not only an important indicator to measure the level of product manufacturing in a country, but also largely determines the country's product quality, efficiency and new product development capabilities. China's current mold development and manufacturing level is at least 10 years worse than the international advanced level. In particular, the contradiction between production and demand of large, precise, complex and long-life molds is very prominent, which has become a bottleneck that seriously restricts the development of China's manufacturing industry.



Mold is the basic process equipment of the industry. In telecommunications, automobiles, motorcycles, motors, electrical appliances, instruments, home appliances, building materials and other products, more than 80% must rely on mold forming, using the mold to produce high precision, High complexity, high consistency, high productivity and low consumption are unmatched by other manufacturing methods. Therefore, we should recognize the situation and look for the direction to accelerate the pace of development, rather than relying on imported products forever. Of course, in recent years, the development speed of China's injection mold industry can not be underestimated, we should use this as an opportunity to catch up with developed countries in the shortest possible time.


Although plastic molds are now the most attractive "cheese", cherry is hard to plant. Due to the complex shape and flexible design of plastic parts, there are high requirements for mold materials, design level and processing equipment, and not everyone can easily get involved. Experts believe that there is still a big gap between China and foreign countries. It is necessary to break through the three major bottlenecks that restrict the development of the mold industry as soon as possible: first, increase the research and development of plastic materials and injection molding technology; second, mold enterprises should go to the park. Development, speed up resource integration; Third, the level of tooling test results and other tooling levels must be kept up as soon as possible, otherwise the development of plastic molds will be constrained

Research Network News:

Mold enterprises should strive to achieve win-win cooperation through single cooperation and vicious competition through cooperation and integration, break the narrow idea of ​​“peer is the family, and maintain fair and healthy competition in the mold market through industry self-discipline.



In recent years, the pace of structural adjustment of the mold industry has accelerated, mainly as the development speed of large, precise, complex, long-life molds and mold standard parts is higher than the overall development speed of the industry; the proportion of plastic molds and die-casting molds is increasing; professional molds for the market The number and capabilities of vendors have increased rapidly. The future development direction of China Automotive Mould Co., Ltd. should focus on the adjustment and positioning of product structure, further improve the manufacturing technology level of molds, and occupy the high-end mold market with complex structure, high precision and high technical content.

It is understood that with the continuous deepening of the reform and opening up policy, the attention and support of the relevant state departments to the mold industry, and the promotion and promotion of social organizations such as the mold industry association, the mold industry in Zhejiang has been developed more rapidly, and the mold market The scale is among the best in the country.

During the 12th Five-Year Plan period, the overall trend of the mold market was steady. At present, the demand for medium and high-grade molds in the domestic market is very large, but domestic molds must meet the needs of users in terms of quality and delivery time. Moreover, the home appliance, automobile, and plastic products industries have the greatest demand for molds. International market: In recent years, labor costs in industrialized countries have increased, and they are moving to developing countries, especially Southeast Asian countries. Its domestic production of high-quality, precision molds, the amount of labor input is large, relying on imports to solve. Therefore, the potential of the medium and low-end molds in the international market is enormous. As long as the quality of domestic molds can be improved, the delivery time can be guaranteed, and the prospect of mold export is very optimistic. In addition, the demand for frame and mold standard parts in the international market is also large. At present, China has only a small amount of exports to the shelves.

Although China's total mold production has ranked third in the world, there are some enterprise manufacturers with better overall level in the industry. However, the current domestic mold industry is characterized by uneven manufacturing process conditions and wide gaps. A considerable number of private enterprises or self-employed individuals are limited by factors such as capital, site, technology and information exchange. Some manufacturers rely on traditional equipment and manual manufacturing, and can only produce some medium and low-grade molds. It is difficult to introduce advanced systems. Mold technology and advanced molding equipment. This has caused increased competition in the middle and low-end mold market. Some mold companies are willing to reduce the price of each other in order to survive, and the low price will inevitably affect the quality of the products. As a result, the users are pitted, they have misunderstood their peers, and they have also harmed themselves.

From the China mold industry market prospect analysis and investment development planning research report to understand that the future development of the mold industry is focused on meeting a large number of needs, but also a high level of technology, especially at present, the domestic mold is not self-sufficient, need to import a large number of molds and can represent Large-scale, precise, complex, long-life molds in the development direction, and because China's mold products occupy a large price advantage in the international market, mold products with good export prospects will also become the focus of development.

Back to 10 years ago, the accuracy of precision molds was generally 5 microns, and the accuracy of the molds will become higher and higher over time. It has now reached 2 to 3 microns, and soon a 1 micron precision mold will be available. This requires super finishing. The mold industry will become larger and larger. This is caused by a multi-cavity that develops due to the increasing size and high productivity requirements of mold-formed parts. Multi-functional composite molds in the mold industry will be further developed. In addition to stamping and forming parts, the new multi-functional composite molds are also responsible for assembly tasks such as lamination, tapping, riveting and locking, and the performance requirements for steel are also increasing.

In particular, the home hardware industry needs continuous development and innovation. The industry is increasingly demanding home hardware, and the home hardware industry is showing different changes. Many furniture hardware manufacturers invisibly separate the two, decorative hardware does not pay attention to functional development, functional hardware is insufficient for its decorative development research, and there is a disconnect between the two.





The mold industry is an important part of China's hardware industry. The 12th Five-Year Plan period is a crucial period for China to properly respond to major changes in the domestic and international development environment and accelerate the goal of building a well-off society in an all-round way. It is also a key period for the healthy development of China's mold manufacturing industry. Although there are many environmental uncertainties, China's economic development is still in the period of rapid growth. The comparative advantage of China's molds in the international mold market still exists. The domestic mold market is expected to continue to be optimistic, and the development of the mold industry is showing a general trend.
