1、 外文资料翻译 Problems and development of mould In modern production of dies and moulds, is the production of various important processes of industrial products and equipment, he it to its specific shape by means of certain raw materials. For example, stampings and forgings by stamping and forging a way t
2、hat is obtained on plastic deformation occurs in the mold of metallic materials, metal die casting, powder metallurgy components as well as plastic, ceramics, rubber, glass and other non-metallic parts, the vast majority through mould forming. Due to mould forming with high quality, high yield, mate
3、rials, low-cost characteristics, is now in the national economic sectors, especially automobiles, tractors, aerospace, instrumentation, mechanical manufacturing, household appliances, petrochemical, light industry and other daily necessities are extremely wide range of applications in the industrial
4、 sector. Now, technology has become a countrys products in the manufacture of the die level one of the important symbols of, research and development of mould technology, promoting the development of the national economy has a special significance. Mold industry to promote the development and the im
5、provement of the quality of industrial production, and to have a great economic benefit, resulting each country attaches great importance to and appreciated. In Japan, mould was known as into the motivity of affluent society, in Germany called Kings in the metal processing industry, in Romania as mo
6、ld is gold. So it can be asserted, as the rapid development of industrial production, mould industry position in the national economy will be growing, mold technology will also continue to develop and play an increasingly important role in the development of the national economy. Mold is the content
7、 of high technology products, is designed for industrial production, and for a specific product is special production process equipment, with the development of industrial products to diversify, mold production, material from the shape, size, quantity, structure, accuracy, conditions of use and term
8、s of life, towards diversified development trends are becoming increasingly apparent. Single piece production mold is essentially according to the order contract, therefore, mold product diversity and single piece production technique features very prominent. Therefore, design, technology, process a
9、nd equipment of the factory and management, has to adapt to the characteristics of this technology. Most sophisticated die requires high-precision machining, testing devices require high precision. Mold processing technology of mechanical, electronic and chemical and optical industry technical elite
10、. At the same time, die reliance on skilled craftsmen is far greater than that of other processing industries. Therefore, advanced technology and skilled techniques rely on the mold technical characteristics of the product. With the rapid development of technology, especially information technology,
11、 and other high-tech applications in mould design and manufacture an increasingly widespread and increasingly demanding high-tech made to die, die of high-tech features will become increasingly apparent, and for skilled techniques rely on will gradually fade. As a basis for industrial production tec
12、hnology and equipment, mold occupy an important position in the national economy, mold technology has also become a countrys level of product manufacturing one of the important symbols. Since the 80 s, Chinas mould industry development was very rapid. Rapid development of the national economy put in
13、creasingly higher demands on the mouldindustry, also provided a great impetus for its development. Over the years, China die and mould industry has been 15% the growth rate of around rapid development. At present, more than 17,000 more mold production plant in China, numbers of employees is about mo
14、re than 500,000. 1999 China mold industrial output value reached 24.5 billion yuan. Gross output value of industrial enterprises accounted for captive use in two-thirds, as the sale of goods of about one-third. In die and mould industry in GDP, stamping mould design about 50%, about 33% plastic moul
15、d, die about 6%, other types of mould about 11%. Since reform and opening up, China die and mould industry enterprises ownership composition of tremendous changes have taken place. In addition to State-owned professional mould factory, mould manufacturers of other forms of ownership, including colle
16、ctive enterprises, joint ventures, wholly-owned enterprises and private enterprises, have achieved rapid development, collective Mold, and private enterprises in Guangdong and Zhejiang provinces have developed most rapidly. For example, and huangyan area, Ningbo, Zhejiang, collective enterprises and
17、 private enterprises engaged in mold manufacturing up to thousands of homes, became the well-known mould town and one of the most dynamic region in the development. In Guangdong, some group companies and the rapid rise of township and town enterprises, to enhance the market competitiveness of its pr
18、oducts, joining the die manufacturing inputs, for example, kelon, midea, KONKA and power group has established its own mouldmanufacturingcenter. Sino-foreign joint ventures and wholly foreign-owned enterprises concentrated in coastal industrialized areas of the mould, is now on thousands of homes. F
19、or example, Wuxi micro research is a Japan-owned enterprises, employees have more than 200 employees, with precision CNC mold processing equipment more than more than 60, 1998 the die output of more than 200 million Yuan. Technical level of China die and mould industry have also made considerable pr
20、ogress in recent years. At present, the country can produce precision precision multi-position progressive die for up to 2 microns, maximum number of stations has reached 160, life 12 billions. In a large plastic mould, now has been able to produce 48-inch TV plastic shell and 6.5Kg of large capacity washing machine plastic moulds, as well as auto mold such as bumpers, dashboards as a whole. In terms of precision plastic mold, the domestic plastic mould, has been able to produce a camera multiple-cavity mould and plastic mould and small modulus gear. In terms of large precision
