[摘要]近年來，中國沖壓模具，塑料模具以及模具和模具CAD / CAE / CAM技術，快速原型/快速模具制造及其他一些特殊技術發(fā)展非常迅速。同時，模具和模具制造技術水平也是評價一些國家的制造業(yè)水平的重要標志。人們已經(jīng)知道了模具和模具制造行業(yè)的重要地位而且模具的制造水平直接決定了產(chǎn)品質(zhì)量，影響全國的經(jīng)濟發(fā)展的能力。現(xiàn)在在中國大型制造技術-沖壓模具得到明顯的改善，諸如汽車零部件模具。比如第一汽車集團中心公司東風汽車公司的模具制造工廠能生產(chǎn)一些大的汽車覆蓋件模具。
 在中國多級進模具是關鍵精密模具的發(fā)展。目前，自動沖壓技術在我國已經(jīng)開始發(fā)展。雙旋轉(zhuǎn)打樁硬質(zhì)合金級進模生產(chǎn)的定子和轉(zhuǎn)子電機可以達到0.2mm的精度，其壽命可達100萬次。

英文摘要
【Abstract】In recent years, mold and die industry and technology are developing very rapidly in China, particularly in relation to stamping dies, plastic mold, die and mold CAD / CAE / CAM technology, rapid prototyping / rapid tooling and some other special skills. In China, people already know the mold and die manufacturing industry's importance. At the same time, mold and die manufacturing technology is also the eva luation of the level of the manufacturing sector in some countries the level of an important symbol. And directly determines the product quality and mold technology, economic interests and development. Large-scale manufacturing techniques - stamping die to be significantly improved, such as auto parts molds.
 Multi-level Progressive Die in China is the key to the development of precision molds. At present, the auto-stamping technology is security can be manufactured in China. Other multi-stage progressive die, such as the 20 - 30 Line Progressive's leading integrated circuit die, carbide production of electron gun parts progressive die and mold production level of air-conditioning into the heat sink, you can produce high-precision.
