  中国铸造模具工业发展到今天,经历了一个艰辛的历程,直到1976年仍处在落后状态。自1977年以来,由于我国机械、电子、轻工、仪表、交通等工业部门的蓬勃发展,对铸造模具的需求在数量上越来越多,质量要求越来越高,供货期越来越短。目前,模具企业为了缩短制模周期、提高市场竞争力,采用高速切削加工技术越来越多。HSM一般主要用于大、中型模具加工,如汽车覆盖件模具、压铸模、大型塑料模具等曲面加工,其曲面加工精度可达0.01mm。在生产中采用数控高速铣削技术,可大大缩短制模时间。经高速铣削精加工后的模具型面,仅需略加抛光便可使用,节省了大量修磨、抛光时间。增加数控高速铣床,是模具企业设备投资的重点之一。
  因此,引起了我国有关部门对铸造模具工业的高度重视,将模具列为“六五”和“七五”规划重点科研攻关项目,派人出国学习考察,引进国外铸造模具先进技术,制定有关铸造模具国家标准。
