1.大量应用工业机械手。1978年美国装备了190台新设备。在205家公司中,有39家采用了342台浇注机械手,有41家采用了410台制壳机械手。 2.用电子计算机处理和控制工艺数据。 3.模壳头几层用硅溶胶作粘结剂,硅酸乙酯用在背层。 4.向大容量熔炼发展。二十年前一般在7—10公斤,目前发展到平均容量为50～100公斤,最大为125～250公斤。 5.采用定向凝固方法铸造叶片。 6.开始采用回收蜡料做浇注系统。蜡回收经过脱水、过滤并加入足够的树脂及其
A large number of industrial robots. In 1978 the United States equipped with 190 new equipment. Out of 205 companies, 39 used 342 casting robots and 41 used 410 crusting robots. 2. Using computer to process and control process data. 3. Mold shell first few layers of silica sol as a binder, ethyl silicate used in the back layer. 4. To large-capacity melting development. Twenty years ago generally 7-10 kg, the current average capacity of 50 to 100 kg, a maximum of 125 to 250 kg. 5 using directional solidification method of casting leaves. 6. Started to use recycled wax casting system. The wax is recovered by dehydration, filtered and added with sufficient resin
