[摘要]近年来，中国冲压模具，塑料模具以及模具和模具CAD / CAE / CAM技术，快速原型/快速模具制造及其他一些特殊技术发展非常迅速。同时，模具和模具制造技术水平也是评价一些国家的制造业水平的重要标志。人们已经知道了模具和模具制造行业的重要地位而且模具的制造水平直接决定了产品质量，影响全国的经济发展的能力。现在在中国大型制造技术-冲压模具得到明显的改善，诸如汽车零部件模具。比如第一汽车集团中心公司东风汽车公司的模具制造工厂能生产一些大的汽车覆盖件模具。
 在中国多级进模具是关键精密模具的发展。目前，自动冲压技术在我国已经开始发展。双旋转打桩硬质合金级进模生产的定子和转子电机可以达到0.2mm的精度，其寿命可达100万次。

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 evaluation 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.

【key words】Mold、Plastic mold、Stamping Die、Accuracy、useful life
