It is understood that the mold is an important process equipment for the part forming process, and is an important basic equipment for the manufacturing of automobiles, motorcycles, electrical appliances, IT products, office automation equipment, light industrial products, medical equipment, etc. Since the products formed by the mold have high precision, good consistency and beautiful appearance, they are increasingly used in the manufacture of structures and interior parts of aircraft, ships and high-speed trains. In addition, the production process can achieve high efficiency, large quantities and materials, energy saving, so the mold is often praised as "the mother of modern industrial production." The level of mold technology has become an important indicator of the level of manufacturing in a country, and it is also the core competitiveness to maintain the advantages of these countries' products in the international market.
“China's mold industry achieved 3% growth in 2009, with sales reaching 98 billion yuan.†Wu Bingshu, secretary general of China Mould Industry Association, disclosed it. Wu Bingshu also said that on the whole, China's mold industry and the developed countries still have a gap of 10 to 15 years, still have to work hard to catch up, to catch up with the dream of a strong country.
According to the figures of China Die & Mould Industry Association, up to now, China has formed Kunshan, Wuxi precision mold industry cluster production base; Botou, Wuhu automobile mold industry cluster production base; Ningbo, Huangyan, Shenzhen, Dongguan, precision mold industry cluster production base. The structure of the mold product is more reasonable. In the current structural proportion of China's molds, the proportion of stamping dies is about 37%, plastic molds account for about 43%, casting molds (including die-casting molds) are about 10%, and forgings, tire molds, glass molds, etc. %, which is consistent with the proportion of mold categories in industrialized countries.
At the same time, the production capacity and technical level of a group of domestic mold enterprises have been greatly improved. Leading enterprises in various mold industries emerged in the development (such as automobile cover molds have 4 major enterprises; large plastic molds include Haier, Warwick, and Quanda; precision stamping molds have Guosheng and Huafu; automobile tire molds have huge wheels and heroic; Casting molds have a steam casting, Ningbo Heli, Guangzhou cavity, Beilun Huiwang; precision plastic molds Wei Ke (Xiamen), Ningbo Henghe, etc. have played a leading role in the industry.
The level of enterprise equipment has generally improved, CNC machine tools such as machining centers, CAD/CAM technology have been widely adopted, and molding process simulation technology has also been gradually adopted. The research and development and innovation capabilities of enterprises have been improved, and new technologies have been promoted and applied. Such as the development and application of 3D design technology, research and development application of information management technology, research and development and application of double material (color) injection molding technology, research and development and application of high gloss seamless injection molding technology, development and application of molding technology for plastic steel products , high-strength plate, unequal thickness welded plate stamping forming technology, high-strength plate hot press forming technology, nitrogen spring research and development application.
The mold level has been greatly improved. The proportion of high-level molds represented by large-scale, precise, complex and long-life molds has reached more than 35%. For example, automobile cover molds can produce B-class complete vehicle molds; precision mold processing precision has been It can reach 0.5 micron; precision progressive die can be used on high speed punches of 2000~2500 times/min; plastic mold precision reaches micron level, adapts to the needs of IT industry development; single set weight is 120 tons, diameter is up to 4 Meter tire active mold becomes the largest mold and so on.
Wu Bingshu emphasized that compared with developed countries, there is still a big gap in China's mold industry, mainly because China is still in the middle and low end of the global industrial chain division, products are in the middle and low grades, and the mold industry is also the same.
According to the data provided by China Die & Mould Industry Association, the total import and export volume of China's molds in 2009 was 3.807 billion US dollars, down 3.03% from 2008. The total import value was US$1.964 billion, a decrease of 2% from 2008; the total export value was US$1.843 billion, a decrease of 4.11% from 2008.
