" Compared with the international advanced level, China's mold industry has a big gap in terms of concept, design, technology, technology and experience. In general, it is still in the stage of tracking and learning, and has not yet reached the stage of informationized manufacturing, management and innovation development. It is only in the middle level of the world. Compared with the international advanced level, there is a gap of about 15 years. The gap between online testing and information management of mold processing is more than 15 years.†Recently, Wu Bingshu, secretary general of China Die & Mould Industry Association, said frankly. .
Mold is the basic industry of the national economy. In a sense, the development level of the mold industry represents the level of industrial development of a country. More than 80% of the products in the automotive, electronics, communications, aerospace and other industries that are under development in China are formed by mold processing. Participants believed that the overall goal of “China's mold level to enter the advanced level of Asia in 2010†as determined by the “Eleventh Five-Year†industry plan has been reached. Although there is still a gap with the international advanced level, the “Twelfth Five-Year Plan†It will definitely bring huge development opportunities to China's mold industry.
Achieve new breakthroughs
With China becoming a manufacturing power, the domestic mold industry has developed rapidly in recent years. According to incomplete statistics, the overall output value has exceeded 100 billion yuan. Taking the Beijing area as an example, there are more than 200 existing mold companies, which can produce hundreds of thousands of molds per year. According to the Beijing Mould Association, the automotive, electronics, energy conservation and environmental protection industries that are currently under development in Beijing require a large amount of mold support, which has greatly promoted the rapid development of the mold manufacturing industry in Beijing. Despite the uneven development of mold enterprises in Beijing, there are still representative enterprises and products such as BYD Auto Stamping Die, Great Wall Peony Plastic Extrusion Mould, and Condip Prec Precision Multi-station Progressive Die.
According to the person in charge of an IT mold company in Beijing, IT molds have a considerable foundation in China, and have introduced advanced foreign technology and equipment. The products produced by individual companies have reached the world level, but most enterprises still have large gaps. . For ultra-large-scale integrated circuits, it is matched with lead frames with lead pins 100 or more and gaps of 0.2 mm or less, precision micro-connectors with precision of 5 mm or more, miniature motor cores with a diameter of 1.6 mm or less, and tubes and electronics. The matching precision molds are the top priority of development.
From the relevant data of China Die & Mould Industry Association, the gap between China's mold and international advanced level can be clearly seen. Such as the highest precision of the mold, the international advanced level has reached the sub-nano level, the domestic advanced level only reaches the micron level; the maximum life of the mold, the internationally efficient high-precision multi-station progressive die reaches 500 million times, the precision die is 40,000 times, injection molding The mold is 20 million times, and the domestic mold can only reach 300 million times, 20,000 times, and 10 million times.
Planning brings new requirements
Wu Bingshu said that from the level of China's mold development in recent years, the innovations of new molds, new varieties, new processes and new materials have emerged, and the number of patents has increased. In particular, the Ministry of Industry and Information Technology issued the "Twelfth Five-Year Plan for Development of Mechanical Basic Parts, Basic Manufacturing Process and Basic Materials Industry" at the end of 2011 (hereinafter referred to as the "Three-Based" Plan), which will surely bring tremendous development opportunities to China's mold industry.
It is reported that mechanical basic parts, basic manufacturing processes and basic materials are the basis for the survival and development of the equipment manufacturing industry, and its level directly determines the performance, quality and reliability of major equipment and host products. Mechanical basic parts are the basic units that make up the machine and cannot be separated, including: bearings, gears, hydraulics, hydraulic components, pneumatic components, seals, chains and sprockets, drive couplings, fasteners, springs, powder metallurgy parts , the basic manufacturing process refers to the casting, forging, heat treatment, welding, surface engineering and cutting processing and special processing technology with large volume and versatility in the production process of the mechanical industry; the basic materials are specifically required for the mechanical manufacturing industry. Small batch, special high quality special materials.
The “three basics†plan is proposed in the development focus. Focusing on the matching requirements of major equipment and high-end equipment, China will focus on the development of 11 types of mechanical basic parts, 6 types of basic manufacturing processes and 2 types of basic materials. Concentrate on superior resources, focus on the development of 20 kinds of iconic mechanical basic parts, 15 iconic basic manufacturing processes and 12 kinds of iconic basic materials and realize industrialization. Large, precise, efficient, multi-functional molds, high-end passenger car body and automobile (super) high-strength steel plate hot forming mold, high-speed precision multi-station progressive stamping die, high-gloss non-marking, laminated rotating large plastic mold, super large scale Integrated circuit lead frame and large ultra-thin LED large plastic mold, multi-material multi-cavity precision electronics, medical equipment injection molds, large engineering machinery tire rubber molds, light metal high-precision die-casting molds and other development priorities.
Wu Bingshu revealed that among the 20 kinds of iconic mechanical basic parts, China Mould will make breakthroughs in the following two categories of logo products: First, the overall body forming mold of the C-class sedan. The surface shape accuracy of the door and front fenders is 0.08~0.05mm, the structural surface accuracy is ±0.05mm, and the over-molded mold assembly size matching and control (including rebound control) inner contour accuracy is within ±0.7mm and the outer contour accuracy is ±1.0. Within mm, the docking accuracy between assembly parts is within ±0.5mm, and the overall dimensional accuracy of the vehicle body is at or near 2mm. The second is a high-gloss, non-marking, laminated rotating large plastic mold. Developed a width of 1200mm and above, mold accuracy u grade, mold cavity A0-A1 mirror finish, mold assembly accuracy ≤ 0.02 high gloss no trace, in-mold decoration technology, large ultra-thin LED large mirror, complex high-efficiency precision car engine Precision injection mold for plastic intake manifold; total temperature error of heating constant temperature pouring system <0.02mm, heating constant temperature ±1°C, H7/g6 precision sliding fit, to achieve efficient injection molding of laminated molds.
