为了实现我国在二十世纪末经济发展总的战略目标,要求电子工业、机械工业和轻工业产品有更高的发展速度。要求它们的品种不断扩大、更新,要求它们有更高的内在质量和外观质量,还需要提高这些产品的劳动生产率和材料利用率。而模具技术是许多工业部门进行生产的重要工艺装备,同时也是发展和实现少无切削、扩大工程塑料应用等新技术不可缺少的手段,因此,在 In order to achieve the overall strategic goal of China’s economic development at the end of the 20th century, it is required that the electronics industry, machinery industry, and light industry products have a higher rate of development. They are required to continuously expand and update their varieties, requiring them to have higher internal quality and appearance quality, and also to increase the labor productivity and material utilization of these products. The mold technology is an important process equipment for many industrial sectors, and it is also an indispensable means for developing and implementing new technologies such as less cutting and expanding engineering plastics.
