1、英文资料及中文翻译The development trend of China Mold In modern production the life of a growing number of products particularly plastics and a variety of panel products such as large-scale structure of more complex shapes single-use drawings and detailed that it is hard for the right to express the shape an
2、d structure of products which requires the design and manufacture molds must document describes the use of computer-aided design tool die maker at the same time the requirements to be a full grasp of the various information products including product shape size material properties accuracy special s
3、urface effects. Some products need customers in kind or model. At present Chinas industrial production is characterized by a diversity of products replacement fast intense market competition. In this case users of mold parts of the request is of good quality and delivery time as short as possible th
4、e better precision molds mold cell the lower the better thus the manufacture of modern plastic mold with the current economic development and meet the above requirements. The rapid development of industrial economy also contributed to the development of mold industry especially automotive lightweigh
5、t environmental protection and development needs require more and more plastic products applied to the car. Now fierce competition from the automotive industry has greatly accelerated the introduction of new models and is the most frequent replacement of automotive interior parts exterior parts. Aut
6、omotive interior parts exterior parts are mainly on the production of plastic molds of the. In fact new products competition is competition time and time of the competition focused on the design and manufacture of molds on. The rapid development of Chinas national economy to the mold industry has ev
7、er-increasing demands and is projected to 2005 only the automotive industry will need a variety of 360000 tons of plastic parts refrigerators washing machines and air-conditioning are the annual output of more than 10 million Taiwan the annual output of color TV sets have been more than 30 million T
8、aiwan. By 2010 in the construction industry and building materials plastic windows and doors of a penetration rate of 30 plastic pipe will reach 50 percent penetration rate which will greatly increase the demand on the mold. In recent years Chinas mold industry has been around 13 percent a year grow
9、th rate of rapid development. It is predicted that Chinas mold industry in the Tenth Five-Year period the growth rate will reach 13 15. Die steel demand will be 12 per annum rate the national annual demand of about 700000 tons while domestic species die steel die steel abroad only existing species o
10、f 60 the annual import of about 60000 die steel tons. Imports account for about a year die in China market about 20 of the total has more than 1 billion U.S. dollars of which plastics and rubber mold of the total imports of more than 50 die stamping die mold the total imports of about 40. At present
11、 the worlds annual output of about mold 65 billion U.S. dollars the output value of Chinas mold industry in the international ranking third after Japan and the United States. Although in recent years Chinas technological level of mold industry has made great progress but as a whole developed and ind
12、ustrial countries still have large gaps. At present Chinas mold industry is imperative to speed up technological progress adjust product mix increase the proportion of high-grade die through the effective demand for quality to improve the level of the home-made molds to reduce dependence on imported
13、 molds. Mold the future of our industry and technology will be the main direction of development: - Vigorously promoting the wider application of CAD / CAE / CAM technology integrated gradually. Modern design and manufacture of molds should be emphasized not only the integration of information but i
14、t should be emphasized that technology integration and management. - Improve large-scale precision complex molds with long-life design and manufacturing technology to gradually reduce the import tool to increase the volume of exports mold. - In the plastic injection mold the positive application of
15、hot runner the promotion of gas-assisted or water assisted injection molding as well as the high-pressure injection molding technologies to meet the needs of the product forming. - To improve the standardization of the level of mold and mold standard parts usage. Die die standard parts is the basis
16、for a large number of applications can be shortened its design and manufacture of die cycle but also significantly improve the manufacture of precision molds and use of performance greatly enhance the quality of mold. Commercialization of our molds standardized rates are less than 30 while developed
