【導讀】成為推動世界經濟增長的重要因素。市場經濟的不斷發展，促使工業產品越來越向多品種、小。生產周期越來越短，于是對制造各種產品的關鍵工藝裝備——模具的要求越來越苛刻。計算機、激光、電子、新材料、新技術的發展，使得快速經濟制模技術如虎。添翼，應用范圍不斷擴大，類型不斷增多，創造的經濟效益和社會效益越來越顯著。在成型概念上以平面離散、堆積為指導，在控制上以計算機和數控為基礎，以最大柔性為總體目標。航空、家電、船舶、醫療、模具等行業廣泛應用。。熱量將金屬絲熔化，依靠高壓氣體將其充分霧化，并給予一定的動能，高速噴射在樣模表面，合材料)加以支撐加固，提高其強度和剛性，連同金屬模架組合成模具。目前該技術被廣泛地用于飛機、汽車的。樣模上，形成金屬殼體，將其剝離后，與樣模接觸的表面即為模具的型腔內表面。壽命可達50萬次，無環境污染。單元不與沖床滑塊聯接，只需滑塊打擊即可完成沖壓工作。單獨使用時它就是1副完整模具。

　　

【正文】 大差距，供應總量不足，進口很多。 （ 3）大型精密塑料模具 塑料模具占模具總量近 40%，而且這個比例還在上升。塑料模具中為汽車和家電配套的大型注塑模具，為集成電路配套的塑封模，為電子信息產業和機械及包裝配套的多層、多腔、多材質、多色精密注塑模，為新型建材及節水農業配套的塑料異型材擠出模及管路和噴頭模具等，目前雖然已有相當技術基礎并正在快速發展，但技術水平與國外仍有較大差距，總量供不應求，每年的進口額達幾億美元。 （ 4）主要模具標準件 目前國 內已有較大產量的模具標準件主要是模架、導向件、推桿推管、彈性元件等。這些產品不但國內配套大量需要，出口前景也很好，應繼續大力發展。氮氣缸和熱流道元件主要依靠進口，應在現有基礎上提高水平，形成標準并組織規?；a。 （ 5）其他高技術含量的模具 占模具總量給 8%的壓鑄模具中，大型薄壁精密壓鑄技術含量高，難度大。鎂合金壓鑄模具目前雖然剛起步，但發展前景好，有代表性。子午線橡膠輪胎模具也是發展方向，其中活絡模技術難度最大。與快速成型技術相結合的一些快速制模技術及相應的快速經濟模具具有很好的發展前景。這些高技術含 量的模具在 “十一五 ”期間也應重點發展。 10 附件 2：外文原文 Mold design and manufacture The mold is the manufacturing industry important craft foundation, in our country, the mold manufacture belongs to the special purpose equipment manufacturing industry. China although very already starts to make the mold and the use mold, but longterm has not formed the industry. Straight stabs 0 centuries 8039。s later periods, the Chinese mold industry only then drives into the development speedway. Recent years, not only the stateowned mold enterprise had the very big development, the three investments enterprise, the villages and towns (individual) the mold enterprise39。s development also quite rapid . Although the Chinese mold industrial development rapid, but pares with the demand, obviously falls short of demand, its main gap concentrates precisely to, largescale, is plex, 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 stateofart 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 multipurpose pound mold and the pound processing and the laser technology in the mold design manufacture application, the highspeed cutting, the superfinishing and polished the technology, the information direction develops . The recent years, the mold profession structure adjustment and the anizational reform step enlarges, mainly displayed in, largescale, precise, was plex, the long life, center the upscale mold and the mold standard letter development speed is higher than the mon mold product。 The plastic mold and the pression 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 midwest 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 . Although our country mold total quantity had at present achieved the suitable scale, the mold level also has the very big enhancement, after but design manufacture horizontal overall rise and fall industry developed country and so on Yu De, America, date, France, Italy many. The current existence question and the disparity mainly display in following several aspects: (1) The total quantity falls short of demand Domestic mold assembling oneself rate only ,about 70%. Lowgrade mold , center upscale mold assembling oneself rate only has 50% about . (2) The enterprise anizational structure, the product structure, the technical structure and the import and export structure does not gather Iin our country mold production factory to be most is from the labor mold workshop which produces assembles oneself (branch factory), from produces assembles oneself the proportion to reach as high as about 60%, but the overseas mold ultra 70% is the modity mold. The specialized mold factory mostly is large and plete, small and entire anization form, but overseas mostly is small but, is specially small and fine. Domestic largescale, precise, plex, the long life mold accounts for the total quantity proportion to be insufficient 30%, but overseas in 50% above 2021 years, ratio of the mold import and export is :1, the import and export balances the after import volume to 11 amount to billion US dollars, is world mold import quantity biggest country . (3) The mold product level greatly is lower than the international standard The production cycle actually is higher than the international water broad product level low mainly to display in the mold precision, cavity aspect and so on surface roughness, life and structure . (4) Develops the ability badly, economic efficiency unsatisfactory our country mold enterprise technical personnel proportion low The level is lower, also does not take the product development, frequently is in the passive position in the market. Our country each mold staff average year creation output value approximately ,ten thousand US dollars, overseas mold industry developed country mostly 15 to10,000 US dollars, some reach as high as 25 to10,000 US dollars, relative is our country quite part of molds enterprises also continues to use the workshop type management with it, truly realizes the enterprise which the modernized enterprise manages few To create the above disparity the reason to be very many, the mold longterm has not obtained
