高压造型是六十年代以来迅速发展起来的一种铸造新工艺。由于它具有生产速度快、铸件精度高等一系列优点,因而在生产中日益广泛地采用,尤其是在汽车、拖拉机等大量流水生产中,推广得更为迅速。我厂生产汽车发动机铸铁件的几条造型线,全部采用了高压造型工艺。造型机的型式有多触头气动微震造型机、平压头电磁微震造型机、无箱挤压造型机等。在调试生产中,我们 High-pressure molding is the rapid development since the sixties casting a new technology. Because of its advantages of high production speed and high precision castings, it is widely used in production, especially in mass production of automobiles and tractors, which is promoted more rapidly. I plant a few car engine cast iron molding lines, all using a high-pressure molding process. Molding machine type multi-touch pneumatic microseismic modeling machine, flat-head electromagnetic microseismic molding machine, boxless extrusion molding machine. In debugging production, we
