陶瓷型精铸锻模是锻模制造中的一种少无切削新工艺,它具有材料利用率高(与锻钢模相比)、机械加工切削余量小、锻打使用寿命长、成本低等优点。据报导,西德、日、美、苏等国家都普遍采用了陶瓷型精铸锻模,每年给锻造行业提供的陶瓷型精铸锻模,约占锻模制造总量的50%左右。我国在70年代中期也开始进行陶瓷型精铸锻模的研制工作。1977年,一机部科技司将 Ceramic casting die forging is a less cutting new technology in the manufacture of forging dies, it has a high material utilization (compared with the forging die), machining allowance small, long service life, low cost Etc. It is reported that the West Germany, Japan, the United States, the Soviet Union and other countries are generally used ceramic casting die, die casting forging industry each year to provide forging die, die forging about 50% of the total manufacturing. China in the mid-70s also started the development of ceramic casting die forging work. In 1977, a department of science and technology will be
