China although very already starts to make the mold and the use mold, but long-term has not formed the industry. Straight stabs 0 centuries 80's later periods, the Chinese mold industry only then drives into the development speedway. Recent years, not only the state-owned mold enterprise had the very big development, the three investments enterprise, the villages and towns (individual) the mold enterprise's development also quite rapid. Although the Chinese mold industrial development rapid, but compares with the demand, obviously falls short of demand, its main gap concentrates precisely to, large-scale, is complex, the long life mold domain. As a result of in aspect and so on mold precision, life, manufacture cycle and productivity, China and the international average horizontal and the developed country still had a bigger disparity, therefore, needed massively to import the mold every year . The Chinese mold industry except must continue to sharpen the productivity, from now on will have emphatically to the profession internal structure adjustment and the state-of-art enhancement. The structure adjustment aspect, mainly is the enterprise structure to the specialized adjustment, the product structure to center the upscale mold development, to the import and export structure improvement, center the upscale automobile cover mold forming analysis and the structure improvement, the multi-purpose compound mold and the compound processing and the laser technology in the mold design manufacture application, the high-speed cutting, the superfinishing and polished the technology, the information direction develops . The recent years, the mold profession structure adjustment and the organizational reform step enlarges, mainly displayed in, large-scale, precise, was complex, the long life, center the upscale mold and the mold standard letter development speed is higher than the common mold product; The plastic mold and the compression casting mold proportion increases; Specialized mold factory quantity and its productivity increase; "The three investments" and the private enterprise develops rapidly; The joint stock system transformation step speeds up and so on. Distributes from the area looked, take Zhujiang Delta and Yangtze River delta as central southeast coastal area development quickly to mid-west area, south development quickly to north. At present develops quickest, the mold produces the most centralized province is Guangdong and Zhejiang, places such as Jiangsu, Shanghai, Anhui and Shandong also has a bigger development in recent years . At present, our country economy still was at the high speed development phase, on the international economical globalization development tendency is day by day obvious, this has provided the good condition and the opportunity for the our country mold industry high speed development. On the one hand, the domestic mold market will continue high speed to develop, on the other hand, the mold manufacture also gradually will shift as well as the transnational group to our country carries on the mold purchase trend to our country extremely to be also obvious. Therefore, will take a broad view the future, international, the domestic mold market overall development tendency prospect will favor, estimated the Chinese mold will obtain the high speed development under the good market environment, our country not only can become the mold great nation, moreover certainly gradually will make the powerful nation to the mold the ranks to make great strides forward. "15" period, the Chinese mold industry level not only has the very big enhancement in the quantity and the archery target aspect, moreover the profession structure, the product level, the development innovation ability, enterprise's system and the mechanism as well as the technology advancement aspect also can obtain a bigger development . The mold technology has gathered the machinery, the electron, chemistry, optics, the material, the computer, the precise monitor and the information network and so on many disciplines, is a comprehensive nature multi-disciplinary systems engineering. The mold technology development tendency mainly is the mold product to larger-scale, preciser, more complex and a more economical direction develops, the mold product technical content unceasingly enhances, the mold manufacture cycle unceasingly reduces, the mold production faces the information, is not having the chart, is fine, the automated direction develops, the mold enterprise to the technical integration, the equipment excellent, is producing approves the brand, the management information, the management internationalization direction develops. Our country mold profession still will have to enhance from now on the general character technology had : (1) To establish in the CAD/CAE platform the advanced mold design technology, enhances modernization which the mold designed, information, intellectualization, standardized level . (2) Establishes in the CAM/CAPP foundation the advanced mold processing technology and the advanced manufacture technology unifies, raises the automated level and the production efficiency which the mold processes . (3) The mold production enterprise's information management technology. For example PDM (product data management), ERP (enterprise resource management), MIS (mold manufacture management information system) and information network technology the and so on INTERMET platform application, the promotion and the development . (4) High speed, high precision, the compound mold processing technology research and the application. For example the ultra fine ramming mold manufacture technology, the precise plastic and the compression casting mold manufacture technology and so on . (5) Enhances the mold production efficiency, reduces the cost and reduces the mold production cycle each kind of fast economical mold manufacture technology . (6) The advanced manufacture technology application. For example hot technology and so on flow channel technology, gas auxiliary technology, hypothesized technology, nanotechnology, rapid scanning technology, reversion project, parallel project in the mold research, the development, the processing process application . (7) The raw material the simulation technology which forms in the mold. (8) The advanced mold processing and the appropriation equipment research and the development . (9) The mold and the mold standard letter, the important auxiliary standardized technology. (10) The mold and it’s the product examination technology. (11) High quality, the new mold material research and the development and it’s the correct application. (12) The mold production enterprise's modern management technology Along with the national economy total quantity and the industry product technology unceasing development. So we should not only improve the mould quality will improve the mould standardization, make the mould technology to get higher levels of improving. 模具设计与制造 模具是制造业的重要工艺基础，在我国，模具制造属于专用设备制造业。中国虽然很早就开始制造模具和使用模具，但长期未形成产业。直到20世纪80年代后期，中国模具工业才驶入发展的快车道。近年，不仅国有模具企业有了很大发展，三资企业、乡镇（个体）模具企业的发展也相当迅速。 虽然中国模具工业发展迅速，但与需求相比，显然供不应求，其主要缺口集中于精密、大型、复杂、长寿命模具领域。由于在模具精度、寿命、制造周期及生产能力等方面，中国与国际平均水平和发达国家仍有较大差距，因此，每年需要大量进口模具。 中国模具产业除了要继续提高生产能力，今后更要着重于行业内部结构的调整和技术发展水平的提高。结构调整方面，主要是企业结构向专业化调整，产品结构向着中高档模具发展，向进出口结构的改进，中高档汽车覆盖件模具成形分析及结构改进、多功能复合模具和复合加工及激光技术在模具设计制造上的应用、高速切削、超精加工及抛光技术、信息化方向发展。 近年，模具行业结构调整和体制改革步伐加大，主要表现在，大型、精密、复杂、长寿命、中高档模具及模具标准件发展速度高于一般模具产品；塑料模和压铸模比例增大；专业模具厂数量及其生产能力增加；“三资”及私营企业发展迅速；股份制改造步伐加快等。从地区分布来看，以珠江三角洲和长江三角洲为中心的东南沿海地区发展快于中西部地区，南方的发展快于北方。目前发展最快、模具生产最为集中的省份是广东和浙江，江苏、上海、安徽和山东等地近几年也有较大发展。 目前，我国经济仍处于高速发展阶段，国际上经济全球化发展趋势日趋明显，这为我国模具工业高速发展提供了良好的条件和机遇。一方面，国内模具市场将继续高速发展，另一方面，模具制造也逐渐向我国转移以及跨国集团到我国进行模具采购趋向也十分明显。因此，放眼未来，国际、国内的模具市场总体发展趋势前景看好，预计中国模具将在良好的市场环境下得到高速发展，我国不但会成为模具大国，而且一定逐步向模具制造强国的行列迈进。“十一五”期间，中国模具工业水平不仅在量和质的方面有很大提高，而且行业结构、产品水平、开发创新能力、企业的体制与机制以及技术进步的方面也会取得较大发展。 模具技术集合了机械、电子、化学、光学、材料、计算机、精密监测和信息网络等诸多学科，是一个综合性多学科的系统工程。模具技术的发展趋势主要是模具产品向着更大型、更精密、更复杂及更经济的方向发展，模具产品的技术含量不断提高，模具制造周期不断缩短，模具生产朝着信息化、无图化、精细化、自动化的方向发展，模具企业向着技术集成化、设备精良化、产批品牌化、管理信息化、经营国际化的方向发展。我国模具行业今后仍需提高的共性技术有： （1）建立在CAD/CAE平台上的先进模具设计技术，提高模具设计的现代化、信息化、智能化、标准化水平。 （2）建立在CAM/CAPP基础上的先进模具加工技术与先进制造技术相结合，提高模具加工的自动化水平与生产效率。 （3）模具生产企业的信息化管理技术。例如PDM（产品数据管理）、ERP（企业资源管理）、MIS（模具制造管理信息系统）及INTERMET平台等信息网络技术的应用、推广及发展。 （4）高速、高精、复合模具加工技术的研究与应用。例如超精冲压模具制造技术、精密塑料和压铸模具制造技术等。 （5）提高模具生产效率、降低成本和缩短模具生产周期的各种快速经济模具制造技术。 （6）先进制造技术的应用。例如热流道技术、气辅技术、虚拟技术、纳米技术、高速扫描技术、逆向工程、并行工程等技术在模具研究、开发、加工过程中的应用 （7）原材料在模具中成形的仿真技术。 （8）先进的模具加工和专有设备的研究与开发。 （9）模具及模具标准件、重要辅件的标准化技术。 （10）模具及其制品的检测技术。 （11）优质、新型模具材料的研究与开发及其正确应用。 （12）模具生产企业的现代化管理技术。 随着国民经济总量和工业产品技术的不断发展，各行各业对模具的需求量越来越大，技术要求也越来越高。所以我们不仅要提高模具的质量还要提高模具的标准化，使模具技术得到更高层次的提高。 6
