高压造型是六十年代以来得到迅速发展的造型方怯。它不但具有生产效率高、造型质量好的优点,而且能提高铸件的精度和减轻铸件的重量。我厂在1977年末建成一条程控半自动高压造型线,于1978年下半年开始试生产。两年多时间的实践,我们体会到只有先进的设备,没有相应的工艺是不能生产出优质产品的。由于高压造型线的生产率高,稍有疏忽就会造成大量的损失。经过比较和分析,制订了适合我厂实际情况的工艺参数,并在生产实践中加以验证和修改。现在,高压造型线的产量不断上升,品种也不
High-pressure modeling is the rapid development since the sixties modeling style. It not only has the advantages of high production efficiency, good shape quality, but also improve the accuracy of castings and reduce the weight of castings. I plant in late 1977 built a program-controlled semi-automatic high-pressure molding line, in the second half of 1978 trial production. More than two years of practice, we realize that only advanced equipment, there is no corresponding technology can not produce high quality products. Due to the high productivity of high-pressure molding lines, a small amount of negligence can result in significant losses. After comparison and analysis, we have developed the process parameters suitable for the actual situation of our factory and verified and revised in the production practice. Now, high-pressure molding line production continues to rise, the variety is not
