模具的发展

模具的发展(中文7600字,英文4800字)
1模具在工业生产中的地位
模具是大批量生产同形产品的工具，是工业生产的主要工艺装备。
采用模具生产零部件，具有生产效率高、质量好、成本低、节约能源和原材料等一系列优点，用模具生产制件所具备的高精度、高复杂程度、高一致性、高生产率和低消耗，是其他加工制造方法所不能比拟的。已成为当代工业生产的重要手段和工艺发展方向。现代经济的基础工业。现代工业品的发展和技术水平的提高，很大程度上取决于模具工业的发展水平，因此模具工业对国民经济和社会发展将起越来越大的作用。1989年3月国务院颁布的《关于当前产业政策要点的决定》中，把模具列为机械工业技术改造序列的第一位、生产和基本建设序列的第二位(仅次于大型发电设备及相应的输变电设备)，确立模具工业在国民经济中的重要地位。1997年以来，又相继把模具及其加工技术和设备列入了《当前国家重点鼓励发展的产业、产品和技术目录》和《鼓励外商投资产业目录》。经国务院批准，从1997年到2000年，对80多家国有专业模具厂实行增值税返还70%的优惠政策，以扶植模具工业的发展。所有这些，都充分体现了国务院和国家有关部门对发展模具工业的重视和支持。目前全世界模具年产值约为600亿美元，日、美等工业发达国家的模具工业产值已超过机床工业，从1997年开始，我国模具工业产值也超过了机床工业产值。

Die history
1 Die position in industrial production
Mold is a high-volume products with the shape tool, is the main process of industrial production equipment.
With mold components, with high efficiency, good quality, low cost, saving energy and raw materials and a series of advantages, with the mold workpieces possess high accuracy, high complexity, high consistency, high productivity and low consumption , other manufacturing methods can not match.  Have already become an important means of industrial production and technological development. The basis of the modern industrial economy.
The development of modern industrial and technological level depends largely on the level of industrial development die, so die industry to national economic and social development will play an increasing role.  March 1989 the State Council promulgated "on the current industrial policy decision points" in the mold as the machinery industry transformation sequence of the first, production and capital construction of the second sequence (after the large-scale power generation equipment and the corresponding power transmission equipment), establish tooling industry in an important position in the national economy.  Since 1997, they have to mold and its processing technology and equipment included in the "current national focus on encouraging the development of industries, products and technologies catalog" and "to encourage foreign investment industry directory."  Approved by the State Council, from 1997 to 2000, more than 80 professional mold factory owned 70% VAT refund of preferential policies to support mold industry.  All these have fully demonstrated the development of the State Council and state departments tooling industry attention and support.  Mold around the world about the current annual output of 60 billion U.S. dollars, Japan, the United States and other industrialized countries die of industrial output value of more than machine tool industry, beginning in 1997, China's industrial output value has exceeded the mold machine tool industry output.
