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 the 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 lightweight 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. Automotive 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 ever-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 Taiwan. 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 growth 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 of 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 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 industrial 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 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 it 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 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 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 countries are 70 percent higher than a year we have imported from a considerable number of mold standard parts the cost of mold-year imports accounted for about 3 8. - The development of rapid manufacturing and rapid prototyping to create molds that is rapid prototyping manufacturing technology to rapidly create a prototype product with the mold and reduce costs. - mold polishing technology equipment and materials to meet the needs of special products. - Promote the use of high-speed milling processing and ultra-precision processing technology and the complexity of technology to meet the needs of mold. - Mold materials and the development of high-quality surface treatment of advanced technology to improve the reliability of mold. - Research and application of high-speed measurement tool reverse engineering and concurrent engineering to maximize the development of mold and the success rate of efficiency. - Development of new molding process and mold in order to meet future multi-disciplinary multi-functional integrated product development and design technology. With the computer software development and progress CAD / CAE / CAM technology is becoming more mature and its modern application in the plastic mold will become more and more widely. This technology also contributed to the modern plastic mold industry which not only reduces the plastic mold design and manufacturing cycle but also improve the success rate of product development and increase the value of plastic mold and market competitiveness. Can be expected that the near future machine tool manufacturing industry from the manufacturing industry to separate and independent national economy has become an indispensable pillar industries at the same time but also further promote the integrated mold manufacturing technology intelligence benefit people and efficient direction. Join the WTO economic globalization so that competition among enterprises of the local competition from the past into a global competition between the same industry trade between the mutual penetration an increasingly competitive. In order to adapt to rapidly changing market demands businesses must be based on the fastest speed best quality lowest cost best service to meet the needs of different users and the competitiveness of the manufacturing sector especially mold. CAD / CAE / CAM integration technology that emerged in this case the. It has become a modern plastic mold manufacturing technology of the inevitable trend of development. And to scientific and rational approach to the plastic mold maker with a well-established tool. Making plastic mold maker in the mold through the use of computers before the manufacture of parts tooling structure processing and cost to modify and optimize repeated until the best results. In short CAD / CAE / CAM technology can significantly shorten the design and manufacture of plastic mold of time reducing the cost of plastic mold and improve the quality of parts plastic mold manufacture of modern an indispensable tool it is reverse engineering and modern processing equipment with modern plastic mold manufacturing in a competitive and popular of the necessary conditions. 中国模具的发展趋势 现代生产、生活中越来越多的产品特别是各种塑料制品及大型覆盖件等产品形状结构比较复杂单使用图纸已很难正确和详尽地表达产品的形状和结构这就要求模具设计制造者必须使用计算机辅助设计文件描述的手段同时要求模具制造者必须充分掌握产品的各种资料包括产品的形状、尺寸、原料的特性、精度要求、特殊表面效果等。有些产品还需客户提实物或模型。当前我国工业生产的特点是产品品种多更新换代快市场竞争激烈。在这情况下用户对模具制造的要求是制件质量好交货期越短越好模具精度越高越好模具格越低越好由此现代塑料模具的制造应与当前经济发展的形势及以上要求相适应。工业经济的飞速发展也推动了模具工业的发展特别是汽车轻量化、环保化发展的需求要求越来越多的塑料类产品应用到汽车上。现在汽车行业的激烈竞争已大大加快了各种新车型的推出而更换最频繁的就是汽车内饰件、外饰件。汽车上的内饰件、外饰件则主要是靠塑料类模具来生产的。其实新产品的竞争就是时间的竞争而时间的竞争主要集中在模具的设计与制造上。 我国国民经济的高速发展对模具工业提出了越来越高的要求预计到2005 年仅汽车行业将需要各种塑料制件36 万吨电冰箱、洗衣机和空调的年产量均超过1000 万台彩电的年产量已超过3000万台。到2010年在建筑与建材行业方面塑料门窗的普及率为30塑料管的普及率将达到50这些都会大大增大对模具的需求量。 近年来我国的模具工业一直以每年13左右的增长速度快速发展。据预测我国模具行业在“十五”期间的增长速度将达到1315。模具钢的需求量也将以每年12的速度递增全国年需求量约70万吨左右而国产模具钢的品种只占现有国外模具钢品种的60每年进口模具钢约6万吨。我国每年进口模具约占市场总量的20左右已超过10亿美元其中塑料与橡胶模具占全部进口模具的50以上冲压模具占全部进口模具约40。 目前全世界模具的年产值约为650亿美元我国模具工业的产值在国际上排名位居第三位仅次于日本和美国。虽然近几年来我国模具工业的技术水平已取得了很大的进步但总体上与工业发达的国家相比仍有较大的差距。目前我国模具工业的当务之急是加快技术进步调整产品结构增加高档模具的比重通过求品质来求效益提高模具的国产化程度减少对进口模具的依赖。未来我国模具工业和技术的主要发展方向将是 大力普及、广泛应用CAD/CAE/CAM 技术逐步走向集成化。现代模具设计制造不仅应强调信息的集成更应该强调技术、人和管理的集成。 提高大型、精密、复杂与长寿命模具的设计与制造技术逐步减少模具的进口
