当前,机械工业面临的主要问题是质量差、品种少、水平低、经济效益差。造成机械工业落后的因素很多,而模具技术是影响机械产品水平的关键之一。由于模具成形具有效率高、质量好、节约材料、降低成本等一系列优点,因而在产品生产中的作用十分突出。据不完全统计,汽车拖拉机、电机电器、仪器仪表、轴承基础件、轻工电子等产品的零件,60～80％由模具加工成形。模具的生产费用已占
At present, the main problems facing the machinery industry are poor quality, low variety, low level and poor economic benefits. Mechanical industry caused by many factors behind the mold technology is one of the keys to the level of mechanical products. As the mold forming has high efficiency, good quality, material saving, cost reduction and a series of advantages, which in the production of the role is very prominent. According to incomplete statistics, automobile tractors, electrical appliances, instrumentation, bearing foundation, light industrial and electronic products and other parts, 60 ~ 80% formed by the mold. Mold production costs have been accounted for
