据预测,到2000年产品零件粗加工的75％,精加工的50％将由模具成型来完成。模具是工业生产的重要工艺装备,模具工业已成为国民经济的基础工业。没有模具就没有产品。制造精密、复杂、大型、长寿命模具的技术,已成为一个国家机械制造水平的重要标志之一。 It is predicted that by the year 2000, 75% of the roughing of product parts, and 50% of the finishing will be completed by molding. Moulds are important technological equipment for industrial production, and the mold industry has become the basic industry of the national economy. There is no product without a mold. The manufacture of sophisticated, complex, large-scale, long-life mold technology has become one of the important signs of a country’s level of mechanical manufacturing.
